similar to: short read while checking ext3 journal

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

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 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

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 have a system with an ext4 filesystem with its journal on an other device (an SSD). Now this SSD dropped of the sata bus so the filesystem went r/o. I would like to remove the journal but it says it can't because needs_check is set. I can't run fsck because the journal is not reachable. Is there any way to solve this? I understand I lost any pending changes in the journal. regards

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 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

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

Hi, I'm running a production server (Debian Sarge install) whose root filesystem (a software raid 1 array of 2 partitions of IDE drive) exhibited the following problem: Oct 28 06:00:06 server2 kernel: attempt to access beyond end of device Oct 28 06:00:06 server2 kernel: md2: rw=1, want=3050401328, limit=16353920 [...] a few of the above line snipped, want is different each time Oct 28

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

Hello On root Partition is .journal visible . On all other Partitions is invisible. At which way I can move it manually to a hiden inode? I have delete with chattr -i /.journal rm -f /.journal and installed ext3 with tune2fs -j /dev/hdb1 And /.journal is again visible! -- MfG / With best Regards Rusmir Duško Registered Linux user: #130654 http://counter.li.org

I am new to ext3 + external journal. Is there any howto I can look at? this is what I understand 1. mke2fs -O journal_dev /dev/md5 2. mke2fs -J device=/dev/md5 /dev/md0 3. mount /dev/md0 / -t ext3 ( hmm.. what do I need to put on fstab?? ) /dev/md5 is a two drive RAID 1 partition /dev/md0 is a 4 drive RAID 5 partition. questions: 1. I am running RedHat 9.0. what extra software I need to

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I created all my ext3 partitions a while back, so the journal.dat file is visable. I'd like to remove them and use the new tune2fs functionality. Can I just mount the drives as ext2, rm journal.dat, tune2fs -j /dev/hd?? and then remount as ext3? Or am I missing something? thanks! - -- Douglas J. Hunley (Linux User #174778)

Hello, I noticed something unusual today. If I "du" a small file (couple of bytes) in CentOS 5, it tells me the file is using 8kb, while I was expecting 4kb which is the block size I'm using. I tried this on several CentOS 5 machines, both x86_64 and i386: $ echo test >test.txt $ ls -l test.txt -rw-rw-r-- 1 filbranden filbranden 5 Mar 11 17:24 test.txt $ du -h test.txt 8.0K
