I just trying installing OpenSuse 11.2 on a Dell Dimension 4500 2.0 Ghz with 512 mb memory and 40 gb hard drive.During the installation the following error was produced: "System Check for partition /dev/sdb1 contains no valid Ext4 file system". After the install process was completed, the keyboard and mouse were not useable
View 7 RepliesIf you have a contiguous partial piece of an ext4 file system (assuming it's perfectly clean), starting from the beginning of the partition, is there any way to check it, or to mount it to get the files whose parents, inodes and data are all completely contained inside?
Have (or maybe had) a very large 11TB RAID 6 array, filled with a single large ext4 partition. Something strange happened when a single drive failed and the array ended up failing 13 out of the 11 drives. I had trouble getting the array restarted, and got to the point where I exhausted all of the options I considered completely safe. I considered a few things that may have worked, but mdadm doesn't seem to have a definite "do not change anything" option. So I decided the only way to be absolutely safe would be to clone the disks before proceeding - then I realized how much time that would take and sent the drives off to a recovery service so they could image them and check it out.
Before doing so, I copied the first 2GB from each disk. I XORd the images from the working drives to reconstruct the data chunks that were on the failed disk, manually assembled the chunks, and am very confident that I have 22GB of "correct" data in a single file. The parity and Q syndromes all matched (with RAID 6 you can still check with only 1 missing device). I've learned the fine details of ext4 from [URL], and have looked at lots of raw data from the reconstructed partition, and it all looks good. The recovery company says that they're not finding many inodes, but I found a lot of them, exactly where they're supposed to be. I tried to mount and e2fsk, but both processes seem to be extremely unhappy that the device size doesn't match the size implied by the file system geometry.
I considered hacking the superblock to manually reduce the size, but I figure that wouldn't work because there would then be more group descriptor blocks than it would expect after the superblocks. I might try doing that and compensating by incrementing the "reserve block count" to compensate. Alternatively, if there is some way to make the file appear to be the expected size with nothing but zeroes after the end of the actual data, maybe I could mount it and not get any errors until I cause the kernel to read past the true end of the file.
I want to convert the file system on my boot drive from ext4 to btrfs.
I have converted by 2nd drive, unsure of how to convert the boot drive and partitions.
I have tried 4 times now to install but it keeps freezing. I wiped my hdd with a tool from UBCD and im starting fresh with a full install of Ubuntu 10.10.I'm installing from a LiveCD. Should I format the hdd in some way before install?

After a hiccup or two I have managed to get a system of sorts running but on trying to copy files from my old computer(via a memory stick) it tells me that Vfat is an unknown file system.On my old computer I am running 32 bit openSUSE 11.2 as a dual boot system with Windows XP and have no problems moving files between the two different file systems.Is it possible to get a 64 bit file system to read 32 bit file system drives and if so how do I do it?
View 7 Replies View RelatedI'm having problems mounting an Edirol R-09HR digital audio recorder (as a USB drive, to read the recording files) on a system running openSUSE 11.2. fdisk or other partitioning tools recognize the device as a "W95 FAT32" drive with a filesystem code of 0b, apparently. I was under the impression that mounting this as a vfat file system should work, but the mount command dies complaining "FAT: bogus number of reserved sectors" and "VFS: Can't find a valid FAT file system." This happens even with a freshly formatted card in the recorder. The device mounts properly with Windows XP systems and late-model Ubuntu/Kubuntu systems, Any clews as to what I'm doing wrong here?

I have a question about ext4,remastersys backup : I have upgraded from 9.04 to 9.10 via the upgrade button in synaptics, so it means that the files system was not touched, which means that my system is still ext3 as it was when I installed the 9.04. I can make a backup of my system as it is configured right now (that's how i like it) using remastersys.
Can I install my system backup into my machine after formating it into ext4 or when I create a backup using remastersys it must stay in the files system as it was when it was backed up? The issue is that right now the 9.10 responds from some reason a little bit slower than my 9.04 responded (to everything e.g. open/close windows etc...) and I read in the forum that ext4 makes 9.10 run faster.
I am so confused! I changed my security profile to 'paranoid' (i'm a linux noob' and accidentally locked my self out of everything! Including su, sudo, YaST, etc. (openSUSE 11.1)

After installing the recent kernel update and rebooting my machine I have found a horrible fact, my computer won't boot anymore. It seems my root partition was corrupted, and running fsck on it just sends me through a endless loop of "Ignore Errors {y}:" and "Force overwrite {y}:". I have already tried the use the repair system on the installation DVD but that doesn't do anything, the pop up asking if I want to repair the file system keeps coming up when I click repair.
View 1 Replies View RelatedMy openSUSE 11.2 system has periodic running of fsck disabled for ext4 filesystems (Maximum mount count = -1, Check interval = 0). What is the reason for this? Is it because fsck is not necessary on a periodic basis with ext4, and only necessary when errors are detected? Or is it because fsck has problems working on ext4 filesystems?
The ext3 filesystems do have it set (Maximum mount count = 500, Check interval = 5184000 (2 months)). I would like to know why fsck is not set to be activated for ext4.
I was unable to boot into my system after I'd just shut it down, so I tried repairing it using my installation media... only to find that though my root Ext4 fs on sda6 was corrupted & *supposedly* repairable, the cd could not do so for some reason! All I can get is a command line, saying something about the root fs being mounted as read only, and I have no idea how to resolve this. I cannot afford to loose ANY of the data I have on here.
View 2 Replies View RelatedI have done it quite often. Inserted and run the computer from a live CD so that the hard drive is not mounted an changed the partitions. It worked on the old reiserfs when I wiped the windows partition on my laptop to increase the space, it worked on ext3 partitions. Now I resized the swap partition and reduced the NTFS partition on my desktop - no problem. But it does not increase the ext4 partition. No error message it just does not do it. I tried several times with the suggested maximal setting, with a custom setting, etc. It just does not change size. Just for interest I booted into Suse11.0 live CD and tried from there. There I get the answer cannot resize partition as the file system does not allow resizing. Is something wrong with the system or does the partitioner not work with ext4?
View 7 Replies View RelatedI have a system running OpenSUSE 11.3 using the bare server configuration.I had a partition for my /srv directory. All was fine until earlier today. I shutdown my system (to remove an old floppy drive from it). When I rebooted, /srv is emtpy (no files nor directories). This is somewhat vexing, as I had several sites running from there, as well as a fair amount of data.The appropriate partition (/dev/sda3) appears using fdisk. However, there is no mention of it in /var/log/messages.Does anyone know how to recover an Ext4 partition?

View 6 Replies View RelatedTired of fat32 fragility, I reformatted a 4GB pen-drive as ext4 using Yast's partitioner. I chose format as ext4 and checked fstab options "can be mounted by user", "no access time" and "ordered journaling". I thought that these fstab options would be ineffective since a removable device won't be added to fstab. when I insert the pen-drive it auto-mounts and the folder /media/EMTEC is created (EMTEC is the volume name). The relevant mount entries are:
Code:
:~> cat /etc/fstab | grep sde
:~> cat /etc/mtab | grep sde
/dev/sde1 /media/EMTEC ext4 rw,nosuid,nodev,relatime,barrier=1,data=ordered 0 0
:~>
There's no fstab entry, as it should be, and there is a mtab entry corresponding to the pen-drive, /sde1. However the /media/EMTEC as created (by udev, I suppose) is owned by root, I can't write to it. But if I change (as root) the /etc/EMTEC folder permissions so it belongs to the regular user, i can (obviously) write to it *and* it stays so *between* remounts. Haven't tried a reboot yet. What I'm not sure is if ordered journaling is OK for a pen-drive - or any kind of journaling, for that matter. Or will this significantly decrease flash memory life? Also, the fstab options set in Yast appear to be remembered by whatever creates mtab, as well as /media/EMTEC permissions. Is that so? Where are these settings kept? How does this work?
Right, I seem to get very random system crashes. My machine will stay up for long periods of time, or sometimes only a few mins, also it doesn't seem related to just using a particular program. As you can imagine this is leading to a bag of woes. After reading on a forum about logs I went to /var/log and in the system log found the following entry . . .
"Jan 10 18:46:10 jon-desktop kernel: [ 92.718896] Either the lower file is not in a valid eCryptfs format, or the key could not be retrieved. Plaintext passthrough mode is not enabled; returning -EIO"
This is repeated multiple times and having checked after a few crashes seems to be the central problem. Being specific about the crashes, they freeze the entire system. Can't ctl-alt-del and sound loops, have to hard reset. I have a feeling that when I first installed Ubuntu 9.10 I selected to use an encrypted file system but have a feeling that I didn't set it up correctly. Not sure exactly what I didn't do but I seem to remember it was to do with generating a passphrase. So . . .
1) What is this error from my logs?
2) Is it linked to me not setting up the encrypted filesystem correctly?
3) Is there a way to check the settings / sort them out properly?
4) Is there documentation for my dullard state which can aid me in this, or is it quite simple?
I've surprisely recognized that it's possible to write a filesystem on a hard disk without any valid partition. Well, the general advantages of partitions are clearly. But what are possible disadvantages or limitaions if you don't use a partition (e.g. if you want to use the complete space as one volume for data mining or so)?

Here is my Fstab:
Code:
I am dual booting OpenSUSE and Windows 7 Pro x64. Each OS is installed on a separate 1Tb hard drive. One question that I have tried to Google for a solution with no success is, how do you access ext4 from Windows? Shortly after I installed OpenSUSE, my OpenSUSE hard drive "vanished" from Windows 7. aturally, I can access all my hard drives from OpenSUSE, which does support the NTFS. I am quite sure that I am not the only person who has this problem as I know that dual booting Linux and Windows is quite common.
View 8 Replies View RelatedI installed opensuse 11.2 some 6 months ago as an alternative to windows 7, on a 44GB partition. Having become my primary OS, I am looking forward to expand the ext4 partition from 44GB to the maximum possible. I have some 24GB unpartitioned space, and free space on NTSF partitions (one of which could be deleted if necessary). What is the best and safest procedure to perform the partitioning.
View 8 Replies View RelatedI'm migrating my OpenSuse 11.3 (which was update from 11.2, 11.1 ........ ) to a new hard drive. My partitions were reiserfs and in the migration I'm "converting" them to ext4, the conversion process is simple and it works fine for all of them except the root one:
1) I create a new partition on the new hard disk (bigger than the original one)
2) I format it with ext4
3) I copy all the data with cp -a from the original partition to the new one
I already have all the partitions migrated to the second disk, then I have tried to do it with the root partition:
-I've booted with a system rescue CD and I've done !9 2) and 3) with no problems.
-I've edited and changed al entries in fstab and grub conf (menu.lst) to point the new partitions
-I've reinstalled grub and it seemed It will be no problems booting, but
It begins booting, the grub menu appears, It begins booting the kernel, but suddenly:
waiting for /dev/root to appear: OK
fsck.reiserfs -a /dev/sda2
........
mount -o ro,ad,user_xattr -t reiserfs /dev/root /root
and it fails, because sda2 is not reiserfs, but why does it try to mount it as reiserfs if I'm not saying anywhere it is reiserfs?
