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 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 Replies View RelatedIf 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'm trying to get a dual boot system. [URL] So i'm just following it.

View 2 Replies View RelatedDuring the installation of Ubuntu 10.04 the partitioner was wrongfully configured to see a functioning btrfs partition as ext4 (without reformatting it). Thus the installation process got stuck at 5%.Installer was run again ignoring the btrfs partition.btrfs-tools was added to the new 10.04, but the btrfs partition is now recognized ast4 with lost+found folder on it.Tried to add the btrfs to etc/fstab as btrfs but t won't mount.Can the partition/filesystem type be changed so that this is actually recognized and mounted as btrfs, hoping my data is still on it somehow?

View 3 Replies View RelatedMy goal ist to install Debian Jessie on a drive with a btrfs subvolume scheme. This is my first time using btrfs and also my first Jessie installation.
My experience is, that partman creates btrfs file systems but doesn´t support btrfs subvolumes (why not?).
I successfully created btrfs subvolumes manually in a shell session during ("expert") installation and manually mounted them to the desired mount points in /target. Installation went through until grub2 installation, which failed.
Is there a best practice to install Debian (Jessie) on a btrfs file system with subvolumes? I want to use subvolumes for /, /home, /var/log and /var/lib/mysql.
Tired 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?
I've just bought a new SSD hard drive:Kingston SSDNow V-Series SNV125-S2/128GB 2.5'' 128GB SATA/300The question is which filesystem whould you recommand and why?BTRFS vs NILFS2 or EXT4?If you choose ext4 would you enable jurnalling?I'm very close to choose Btrfs.Any experience with running any of these on your SSD?

View 2 Replies View RelatedIt started when I wanted to dual boot Windows 7 and Opensuse off of my netbook (No DVD/CD drive) I tried install suse from an external hard drive and I botched it. I ended up erasing EVERYTHING off of my internal netbook hard drive. Windows and all.
Well, I had a couple of other computers so I studied up and eventually successfully installed OpenSUSE 11.2 on my external hard drive (11.3 being the one that I accidentally erased everything with, so kinda scared of it) and now I want to install openSUSE 11.2 on my internal netbook hard drive.
I can not use disks
I can not use a flash drive (For some reason, even if I make it bootable, it will not load up, this could be because it's actually a 8GB microSD card that is placed in a USB card reader.)
I can not use an external hard drive because that's what I'm running suse off of.
I've tried reading up on how to install suse on another drive off of the hard drive and I've gotten as far as whenever I boot up the netbook with the suse external hard drive connected it will ask to boot into OpenSUSE, the Fail Safe, or to install OpenSuse. When I select to install it it gives me the Error 18 Unknown File system.
I've tried formatting the internal hard drive twice. One as NTFS and again as EXT4. Neither seems to effect it other than when it's ext4 I can open it and it contains a Lost and Found folder.
When I interrupt the boot sequence by pressing c and going to the terminal and I use the root (hd +TAB command it tells me I have a hd0 and a hd1. The hd1 only has 1 partition which is ext4, which I'm assuming hd1 is the internal hard drive (I'm not sure how to check) and the hd0 is the external hard drive, which has three partitions. One with an unknown file system and two with ext4. When I try to enter the set up from the terminal it gives me the same error for any thing I put it (e.g. root (hd0,0) gives the same error as root (hd0,1), or root (hd0,2) and root (hd1,0)
Something like it cannot locate these two files I'm assuming it needs to boot. If anyone finds this relevant I'll retry it and post the files its missing.
I've been searching for awhile and can't find any threads that can solve my problem. From other threads, however, I have noticed that I should probably include my menu.lst, listed below

View 1 Replies View Relatedtelling me if this behavior of my openSuSE 11.2 installation is normal? I use a 64-Bit openSuSE 11.2 with kernel 2.6.31.x with root partition ext4. After adding and updating from repository kernel:/HEAD/etc to 2.6.34-rc4 I can not boot anymore due to a lack of module ext4. I thought today ext4 is stable and fix built-in in the actual kernel releases, isn't it? The error message at boot time: FATAL: Module ext4 not found. Which is right because in /lib/modules/<kernelversion>/kernel/ there is NO 'fs' subfolder. Isn't the kernel:/HEAD/ repository the official update path to get a newer major kernel? (besides openSuSE's Updates for security reasons) Do you know how I can fix it without self-compiling?

I'm trying to install OpenSUSE on an external usb drive but when I boot from USB, all I get is a message saying "Missing Operating System". I've tried different ways of partitioning the drive either by letting OpenSUSE do it automatically or doing it myself. It's just a basic partitioning scheme, with swap on one partition sdb2 and the rest on root sdb1 .
I made sure to have GRUB be installed on the root partition of sdb (usb drive) instead of in the MBR (I've installed Fedora and Ubuntu on usb drives this way).
I recently upgraded to Ubuntu 11 and a few days later my ecryptfs filesystem began misbehaving in a weird way. In my home directory, many subdirectory names are duplicated verbatim. Here's an ls -F excerpt:

I can no longer access files in those directories (if I ls the directory, it appears empty; I can cd to it, but there's nothing inside). Not all of the directories are duplicated/damaged like this, but most are. A few non-directory files are also duplicated in this fashion, so for example:

View 2 Replies View RelatedI'm trying to figure out why files in linux are oriented in the folders the way they are. In Windows it's much simpler to picture. You have program files (C:Program Files(x86), system files (C:Windows), user settings for programs or personal stuff(C:User), and some weird folder names. I was noticing that the Ubuntu ext4 filesystem is a little more complicated. Some folder names are self explanatory, but others are not. Is there a guide, or some reading material on the history of the linux filesystem and how it morphed into what is presently used in Ubuntu?

View 9 Replies View RelatedI recently downloaded Ubuntu 10.10 and installed it onto a 250gb removable disk using a 240gb ext4 partition and a 10gb swap space.
I am using a Sony VAIO (VPCF115FM) and it would appear that my BIOS is very limited as to bootup options. I can only choose internal HDD/external device/network/CD Drive. I cannot check whether or not my BIOS is able to recognize the external ext4 (but from experiences so far it would seem that it cannot)
After much tinkering i got my internal windows 7 to recognize the drive as ext3 (Used ext2 volume manager to add a registry entry for the drive). However, I need to unplug and replug in the drive for it to be recognized, if i leave it plugged in from booting it shows up as unrecognized.
Summary: I would like to be able to boot up Ubuntu off this external drive, but as of now it would appear that my BIOS is unable to recognize the drive. Windows can recognize it as ext3, and I can access contents of the ubuntu partition from windows.
how I could get this working that would be fantastic, i've tried formatting the drive to other filesystems (ext3,ext2,XFS) but none of them would work either, so any information would be sweet
