General :: JFS /data Partition Full
Feb 8, 2010
I have a 10gb partition I use for data. The /home is there, and I mount any other data partitions (like /music stuff) onto /data. These other mounted partitions add up to something like 60gb of diskspace, but since they're just mounted on /data, I believe they only take up 4096 bytes per mount point.
Some time ago, I found that the /data parition was full. There was only 330mb of data in /home, so I was perplexed. I found a cache dir under .opera that reported itself as having 132TB (yes, that is terrabytes) of files. I thought deleting the offending directory was the answer, so I deleted that cache dir and every file or subdirectory in it, but the /data partition is still like 99% full. I am a wee bit confused.
This very full /data partition is my only jfs partition. The other mounted filesystems are either ext3 or ntfs. Is it possible that the journal of this filesystem is corrupted? Or is hidden somewhere on the /data parition, taking up a bunch of space? (I obviously don't know enough about filesystem to know whether or not this is a likely scenario.) Is it possible to zero out (or delete and re-create) the journal, if so? The only other thing I can think of is to move all the /home data off, delete the partition, then re-create it and move /home back. I will do that if need be, but I'd rather learn something from the experience, weird as it is.

I didn't realize my system drive had filled up... and TaskWarrior overwrote my 'pending.data' with a 0-byte copy. d-: I had worked SO hard to get all my tasks imported from various other notes (many of which I deleted along the way), and hadn't yet prepared for the possibility of data loss. Should've set it up to use my Dropbox...why doesn't TaskWarrior make ANY backup buy default? That data is so important, and yet so small and trivial to backup. Anyway, my 'undo.data' is totally intact and seems to contain all the information theoretically needed to reconstruct 'pending.data'. Unfortunately right now I have no sample 'pending.data' to look at. d-: OR: does anybody know of a simple Linux utility I can use to recover previous file versions? It's possible no data was overwritten, since the replacement is empty.

I've been using Ubuntu 10.10 for just under a week. Recently, a partition called 'Data' has disappeared, and all my music and documents along with it. The folder is not to be seen in Places or on my desktop. My only way of finding it is to go to terminal. But when I try to open it there I get an error saying I don't have permission to read it. In Puppy Linux and SliTaz I can easily find the partition and read it. What should I do to bring it back in Ubuntu?

df -h reports that my /var partition is full..
Filesystem Size Used Avail Use% Mounted on
/dev/sda6 2.0G 1.4G 454M 76% /
/dev/sda1 99M 16M 79M 17% /boot

[Code]....
Does anyone know of anything that might be on the /var partition and taking up space that I can't see, or just why df -h is reporting that it's full?

I am having trouble logging into my ubuntu 11.04 desktop. When I type my username and password to login my screen goes blue, as if it is going to next show my desktop wallpaper, but then it loops back to the login screen. I had no idea why and so I went to ALT-F1 and typed in "df" and it turns out that my root partition is full. This is strange since I set aside 40GB for it and I didn't install anything or that many programs that would fill it up. Anyhow, is this fixable by booting to a live cd and using gparted to make root bigger or is there a better way to fix this?

I'm sure I've done this before and never ran into trouble so it's not like I wasn't thinking, just something went wrong this time and I'm screwed. I'll post a fdisk -l to show ya what I mean.
[root@localhost ~]# fdisk -l /dev/sda
Warning: invalid flag 0x0000 of partition table 5 will be corrected by w(rite)
Disk /dev/sda: 1000.2 GB, 1000204886016 bytes

Well I tried to install Pclinuxos 2010 to the same partitions as Mint 7 and basically just over write it (this I have done before) but this time Pclinuxos says there is a bad block and it can't copy files to / (sda7) I didn't think much of it at the time and thought I would try to install it (Pclinuxos) on a separate 100 gb usb drive and it was a sucessful install.
After booting Pclinuxos I try to access my 1TB sda hard drive and I can ony access sda1 .....when I look at /dev/sda in gparted is shows the whole disk as unallocated.I have done nothing at this point in time other than what I just said because I am very afraid of loosing all my pictures and everything else on that disk....and for those that will say always back up ....if ya think I'm not kicking myself right now your dead wrong......

So I tried adding a new, 2nd hard drive to my Ubuntu 9.04 desktop for some additional storage and only managed to kill my system so that it won't boot up anymore (I just get a blinking cursor after the BIOS does its thing).I could sure use a little help getting back to a functioning system, and then adding the second drive. I tried following the instructions from this link to add the 2nd drive:
(So the forum rules won't let me post the link, neato. Here it is with spaces added):

I want to install Ubuntu side by side with Windows. I have a big NTFS partition that has a folder with the same name as my username (let's say "joe"). Inside "joe" I have my personal files. Outside "joe" but still in the partition, there is random stuff that doesn't really belong anywhere, or now useless programs that I had to install there because the main Windows partition ran out of space. If during the Ubuntu installer I choose to use that partition as /home and make a user called "joe", will everything work fine?

While attempting to install FC12, Anaconda took it upon itself to overwrite the partition on my backup disk. Now I need to figure out if there's a way to get at least some of my data back. If there's a better place for this question, please let me know and I will happily move it. Using Linux since 1993, other Unixoid systems since 1986. I bought this machine back in 2004 or so. It was a pretty decent machine back then, but it's showing its age now: 370Mb of RAM, 2 hard disks with 80Gb and 120Gb (I don't think the other specs are relevant, but just let me know if I'm wrong). In a fit of insanity, I decided to install Gentoo on it. Don't get me wrong: I love certain things about Gentoo. But the constant fiddling that's required, while it can be fun at first, gets old kinda quick.
So various and sundry things have been going wrong with it here and there (CD-ROM, sound card, etc ad infinitum), and, finally, it wouldn't even load X any more (almost certainly some final Gentoo update which broke something) and I said "screw it, I'll just put Fedora on it." This is what I use at work, and plus I have a good friend who has far more patience with admin stuff than I do and Fedora is what he knows. So, last night, I pick up an FC12 CD that I have lying around and decide to finally just reinstall the whole thing. I went so far as to buy myself a Passport USB drive, 319Gb, and have been backing up up all my stuff very regularly to that drive. I go through one final cycle of backing up and verifying before I start the reinstall.
So my drive is solid, and contains everything I could possibly need (and probably quite a bit of stuff I don't). After booting into FC12, I used Palimpsest to explore the partitions on the existing hard disks. Not sure which was which, I mounted the Passport, where I have cleverly saved a copy of my fstab. Using this, I can see which of my partitions were /boot, /, /home, etc. Most of my personal data has been put into separate partitions so that I could reinstall without blowing away the data. I hope that I can do that there, but, if I can't, no matter: I have a backup. I find some bits of empty space and delete a few of the partitions and recreate them, consolidating the empty space. Still confident in my backup, of course.
So I run Anaconda. Nothing happens. Eventually, I figure out that it won't run the graphical interface because I don't have enough memory. I can use the text version, no biggie. It gets to the part about the disks. I tell it which hard disk to install itself onto. For some reason I think it's going to pop up and ask me about the existing partitions and whether I want to keep them or rewrite them (maybe that's a previous version of Anaconda? or a different installer altogether, who can remember). It does not. It babbles something at me about LVM (which I've personally never really used before), and then promptly locks up. Obviously standard Fedora on a low-RAM machine like this is doomed to failure.
I poke around on the Internet, and I eventually stumble on the Fedora "spins" and select FC13/LXDE. Hopefully this will have better luck. Reboot with the new CD, take a look at my hard disks. It has completely overwritten the old partitions, replacing them with LVM partitions. But not a big deal: I have a backup. Take a look at the Passport. Its ext2 filesys has also been replaced with an LVM partition. Proceed to beat head against wall. So, obviously what happened is, since I (foolishly) had the backup drive mounted at the time I ran Anaconda, it assumed I wanted it to take over that drive as well, and just formatted everything it could lay hands on as LVM. It certainly never asked me my opinion on the matter.
But, fine, I shouldn't have had it mounted. The question is, what do I do now? My first, panicked instinct, was to just set the partition type back to 83 (I believe LVM is 8E), which I did (using cfdisk). That might have made it worse; I dunno. But I'm pretty sure I haven't written anything else to the disk since then. I've tried testdisk (nothing useful; although it can seemingly find the underlying deleted partition, it won't actually do anything with it), and a bevvy of Windows Linux recovery programs (Stellar Phoenix, DiskInternals, Raise, and R-Linux), all of which were completely useless except for R-Linux, which scanned the disk for eight hours and was still going when I had to interrupt it (I may come back to that one, but so far it doesn't look too promising).
My primary problem is that I can't make an image of the disk because this little Passport is the biggest hard drive in the house. I would certainly feel better if I could image everything off it and then play with the image. But, of course, it doesn't matter that very little of that 319Gb was actually being used: I still need 319Gb worth of space to make an image. I ordered another (larger) Passport, which should be here Wed. Once I have that I believe I can do something like so:
Code:
dd ifs=/dev/sdX ofs=/mnt/bigpassport/smallpassport.img bs=512
Right? Then I can muck about with that image in some amount of safety.
Of course, I also have the original hard drives, which are not so large. testdisk can identify the original partitions on those too, but, again, won't actually do anything with them. If I could find something that would image just the partitions I care about, I could probably save those as well, but I don't have any other external hard drives with 120Gb of space free. Can I somehow take the info that testdisk is giving me about those original partitions and use dd to get only that part of the image? Are there other recovery tools I haven't considered? I have a Windows (Win7) laptop, a Linux laptop (FC10, I think), although its power cord is flaky so it's not too reliable, a smaller Mac, a really old Windows box (XP on it, I think), and this formerly-Linux box, which I can only boot off CD's at this point. There's nothing on this disk worth the 500 bux that professional data recovery would charge me, but it's worth a day or two of my life to try to get at least some of it back.

A HP Netserver LP2000r, with original SCSI controller and HP NetRaid-2M controller, 3x 36GB Ultra3 HDD in RAID5, Debian (sarge/etch), has crashed after 992 days without reboot. From all that I can see, a hardware failure, most likely with the memory. The HP Diagnostic tools cannot find any problem, but everytime I boot into Knoppix, I get between 2minutes and 2 hours of runtime, and then either a kernel oops or just a complete and sudden halt.
Well, the box has earned its money. However, there is some data on the drives that I need to recover (yes, I have beaten myself up properly about not backing up that data, don't even go there !). There are three partitions: sda1 is /, sda2 is swap and sda3 is a LVM volume with 3 logical volumes on it. As far as I can tell, the hardware defect must have been creeping in and has made a total mess of the inodes in all these partitions.
After booting into Knoppix, I can restore the volumes using pvscan, vgscan, lvscan, vgcfgrestore and vgchange. If I try and mount them: mayhem. So I try and check them, using fsck.ext3. All sorts of interesting nonsense, such as a completely empty inode 11 (the first inode) and then obviously from there on all else is pointless. I tried using debugfs, but the information on what to do with it is somewhat spurious.
P.S.: Tomorrow I will go and get myself a 16GB Flash Drive and then hopefully I will be able to dump the partitions one by one onto that drive and transfer the images onto a different computer for analysis and data recovery.

On my laptop (Dell Studio 1745) w/500GB HD, I have a common data partition shared by openSUSE. Fedora, FreeBSD, and windoze 7 currently. I would like to encrypt this partition (/Common) and have it accessible from all distros either with a passphrase key in /root or on a flash key. I've been researching on the web and there seem to be several possibilities using eCryptfs, Luks, cryptosetup, or any of several methods.
My question is, what have people here used and how well did it work? Also, what was required for setup (I'll probably have to explain/teach it to my wife who is technology challenged-but I still love her anyway) and my daughter who's just getting into linux. I would like to be able to keep the entire directory on the hard drive but also have the ability to copy it to external USB device for transport.

I wanted to migrate from ubuntu karmic to the latest ubuntu 10.10, but i already have a lots of data on my hard disk in home directory. i was thinking if it is possible to transfer all the data to one directory and make a separate partition of it , so tht when i install a fresh copy of ubuntu 10.10 on my system i need not format this new partition ,which contains al my data.is it possible tht this new partition will automatically get mounted on the new system without the need to execute commands from terminal every time i start my system. if there is any other alternative way for solving this problem i would follow tht too.the reason for my migration is that karmic is really troubling me a lot and so many applications including my sound device have failed to work and i am not able to rectify them..

I've got an external hard drive with one large data partition on it. I also have four computers to connect it to (individually, not at the same time). Three machines are running Slackware and one is running Ubuntu 9.10. I need to be able to just plug the drive into whichever machine, mount it (preferably to the same location each time) and not have to worry about user permissions and such. Do I just chmod 777 all the files and folders or is there a better method for different 'users' to access the same partition? And how about mounting to the same location each time?
Now the second part of my question I'm pretty sure I'm not able to do but just in case..... is there any way to encrypt the information safely and make it compatible with a Windows XP machine?

following problem. A friend phoned me in despair. Her Ubuntu didn't start any more - ASUS-Laptop switched on stops at a ramfs-prompt.
I started Puppy-Linux from DVD-Drive. Worked fine. But puppy can't mount her /dev/sda1 partition either. At least you can see that the partition is still there. Fsck stops with an error. May be the initial problem is a sort of bad hardware by which bad bytes were written to the hard drive. Hard drive and/or memory could be replaced but not the data.

These following ext3 partitions contain identical data. As we can see, the larger the partition size, the more space is required for the same files:
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/loop11 3965777 561064 3199964 15% [...]
/dev/loop19 573029 543843 29186 95% [...]

I used a Kingston 8Gb flash drive as a live usb recently (copied the live iso image over using dd). I am done with the installations and all but seem to have a problem. i cannot format my flash drive. It now shows as a live CD (800 or so mb). Is there a way to fix the partition table back? I guess if i copy a partition table image from some other 8 gb drive that might fix the problem but i dont have any other flash drives. Is there a solution possible or am i stuck with a live usb forever

I usually repartition a disk by backing up, deleting the partitions, formatting them and repartition. I just did a 200 gig backup (so i am safe) and i want to join 2 (ext3) partition together, sdb1 (data4) and sdb5 (data5) into one big partition. Is there a way to do it without scraping the data in sdb5 (data5). It would save me from rewriting the data back to that new partition (200 gig is time consuming).

KDE 4.6 - opensuse 11.4.
I have a separate ext4 partition which contains all my data (music, movies, etc). When I delete files from this partition it is very slow because it copies files from my data partition to the Trash folder in my home partition. How can I avoid this? Can't the trash be configured so that it uses a trash folder in each partition instead of copying files to another partition (which is slow).

I am investigating full disk encryption and have made a DD copy of the hard drive which has been encrypted, this DD file is stored on my computer for analysis.
First question is - Anyone know how i can access data in this DD file even though its been encrypted?
Second question - Is there a DD command where i can image the systems memory? I ask this because when a system is turned on, to get past the pre-boot authentication stage you need a password. From what i understand, this password will be passed in to ram when power is applied to the system. Making a copy of the memory will also copy the password?

I have a RAID 5 array, md0, with three full-disk (non-partitioned) members, sdb, sdc, and sdd. My computer will hang during the AHCI BIOS if AHCI is enabled instead of IDE, if these drives are plugged in. I believe it may be because I'm using the whole disk, and the AHCI BIOS expects an MBR to be on the drive (I don't know why it would care).
Is there a way to convert the array to use members sdb1, sdc1 and sdd1, partitioned MBR with 0xFD RAID partitions?

Just ran into an uncomfortable problem. I usually never save any documents on my machine, and keep all my stuff on an external USB hard disk. (an 80GB TrekStor DS microdisk q.u)
Well yesterday this disk just would not mount.
Read through related posts but nothing seemed to work. Even tried it on a Windows machine.
Tried TestDisk utility. Found nothing wrong with the drive, but still could not repair the MBR.log code...
Palimpsest Utility recognized the drive, but just will not let me do anything with it except format it.
How can i repair the partitions and MBR without losing all my data?

Original disk:
XP NTFS primary
Linux / ext4 logical
Linux /home ext4 logical
Win 7 NTFS logical
NTFS data logical
swap space
NTFS recovery partition
I tried to install linux, as there was a problem with XP overwriting grub, I chose write grub to /dev/sda8 (which is where the linux install was appearing earlier).
I guess this borked the filesystem somehow. Now the NTFS data partition and the swap space are appearing as one free space.
Well actually before that some linux live CDs (including gparted were seeing the entire drive as unpartitioned). I had to go into XP and delete the /ext4 partitions.
Is there any way for me to recover the NTFS data partition ?

I have an external 3.5" USB 250Gb HDD which is showing symptoms of hardware problems (repeated /var/log/messages errors of "reset high speed USB device using ehci_hcd"). This was originally plugged in to my NSLU2 running Debian Etch. I have just installed Ubuntu Desktop 9.10 to a spare Pentium-3M laptop and was hoping to copy the contents of this HDD to a fresh drive. However, I cannot mount it even read-only; mount -o ro /dev/sde3 /mnt/disk fails, and the /var/log/messages error is "recovery required on readonly filesystem", "write access unavailable, cannot proceed". I cannot understand why mounting a disk read-only should require write access. Following advice I googled elsewhere, I tried running mke2fs -n /dev/sde3 to try to list the alternative superblocks - but once again I got the error that the device was read-only. How can I go about accessing the data on this disk?
