similar to: recovering corrupt file system

well, the next place to go, if fsck isn't enough would be to to try debugfs(1) man debugfs.

Have I just overwritten some of my virtual drive, and if so, is there a way to recover? On a linux host I use LVM logical volumes as the backing for my virtual disks. Using the Virtual Machine Manager 0.9.1 GUI I did this: 1. select source machine, go into details, select virtual disk and removed the hardware. 2. select destination machine, go into details, add storage. 3. click "select

Hi, Michael I have met ext4 error when using vhost_scsi on arm64 platform, and suspect it is vhost_scsi issue. Ext4 error when testing virtio_scsi & vhost_scsi No issue: 1. virtio_scsi, ext4 2. vhost_scsi & virtio_scsi, ext2 3. Instead of vhost, also tried loopback and no problem. Using loopback, host can use the new block device, while vhost is used by guest (qemu).

I have been playing with external journals some more and thought I should share some experiences. I am running 2.4.16 with the ext3 patches from Andrew Morton and e2fsprogs 1.25 I have an ext3fs filesystem on an 8 drive RAID5 array and place the journal on a partition of the mirrored pair that I boot off (all drives SCSI). I have tried pulling the power cable and seeing what happens. I finally

My UPS failed and my server took an 'unscheduled outage' a few weeks ago. The only casualty appears to be a volume I used for backup. I usually maintain data on multiple hard disks, but in this case I errantly had some data (of marginal value) on this file system. At this point, the data is not worth enough for me to send the drive out for data recovery, but it's worth enough to

After a (hardware) crash yesterday, I was unable to boot up due to unrecoverable ide errors (according to the printk()s) when accessing the root filesystem's journal for recovery. Unable to recover, I tried deleting the has_journal option, but that was disallowed given that the needs_recovery flag was set. I saw no way to unset that flag. Unable to access the backups (they were on a fw

Hi all (and developers in particular) I just got bitten by this Assertion. The one that starts as in the subject, and ends with: "!(((jh2bh(jh))->b_state & (1UL << BH_Lock)) != 0)" Google reminds me that it was mentioned a few times earlier this year, but I couldn't find any statement saying that it has been fixed. I got this in a 2.4.16 kernel, though the

Hello, I have 2 boxes with 1.5TB storage with ext3 fs, and the kernel is 2.6.11.8. I'm using E2fsprogs 1.37 for FS creation. And, Filesystem revision #: 1 (dynamic) There are 2 scenarios: 1. All SATA drives, RAID5 2. All PATA drives, RAID5 and wrapped in log volumes. I'm having lots of issues with fsck. I did search, but somehow not getting the right information. needs_recovery

Hi, hoping that someone on this list can help me here is the Problem. After a crash it seems the journal could not be recovered. This is what mount gives: root@wuehlkiste:# mount -t ext3 /dev/hdb2 /mnt mount: wrong fs type, bad option, bad superblock on /dev/hdb2, or too many mounted file systems and this is the corresponding logfile-entry: Nov 27 11:16:13 wuehlkiste kernel: attempt to

Hi I was running few tests on the Ext3 filesystem having an external journal; basically trying to check recovery in crash scenarios. I started with simple scripts doing some filesystem operations on the ext3 partition and crashed the system with a direct poweroff. On reboot, I also corrupted the journal device by "dd"ing it out with blocks of zeroes. Now, when I try to mount the

Hello, We have run and stopped by chance command "fsck -y" on one of our raid disks (with ext3 file system). After that we have found that SOME files disappeared (they are not seen in the directories where they have been before). The data are extremely important and contain a lot of programs, scripts for some data analysis and very hard to recover by hands. I have run ''fsck

Hi Ted and all, I have a couple of questions near the end of this message, but first I have to describe my problem in some detail. The power failure on Thursday did something evil to my ext3 file system (box running RH9+patches, ext3, /dev/md0, raid5 driver, 400GB f/s using 3x200GB IDE drives and one hot-spare). The f/s got corrupt badly and the symptoms are very similar to what Eddy described

Hello. Is there a simple way, at a shell script level, of finding out whether an ext3 fs has a sane journal, other than mounting it or running a full fsck ? I may quite well be missing a few things here, but what I think I'd like is some option extra to e2fsck that says "if this is a journalled filesystem, and it was shut down uncleanly, just replay the journal and check for immediately

Hi, I have a 20GB partition on a hard disk that just developed bad blocks. Fortunately, I had backups for the most important data on it, but I'd like to recover some files that were too large to backup. When running 'e2fsck /dev/hdc3', I get the following message: e2fsck 1.27 (8-Mar-2002) Group descriptors look bad... trying backup blocks... e2fsck: Invalid argument while checking
