similar to: External journal has more than one user

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

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

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

I have a Debian system from a Knoppix distribution. I started out with ext2 but decided to change to ext3. tune2fs -j OK. However the system boots with a warning ....ext3 mounted as ext2. proc/mounts confirms this and no journal is running. So I have to make an initrd. Did so using instructions in the Debian Reference and this did not change anything. Any attempt to use the img produced was a

We are having problems remounting an ext3 filesystem using an external journal device. The filesystem in question was working fine until the server was rebooted. This is what we see on dmesg when trying to mount: EXT3: failed to claim external journal device. The external journal lives on a LVM2 logical volume and it seems to be accessible ( we can dumpe2fs and see filesystem information).

Hi, I tried to convert my root partition from an ext2 to ext3 fs using tune2fs. I'm running a 2.4.10 kernel with ext3 support, but the partition is not mounted ext3. In fact the journal feature is missing from the superblock: # cat /proc/filesystems | grep ext ext3 ext2 # tune2fs -l /dev/hda6 | grep features Filesystem features: filetype sparse_super # ls -l /.journal

-----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)

Greetings, I recently cpio-ed some user directories onto a new ext3 partion. After putting this file server's partition into production, I noticed a .journal file in the root directory of the partition dated well before the creation of this partition. I think this .journal file was copied over from the old filesystem and I am concerned that I over-wrote this current filesystem's

Hello Is it possible to externalize the journal of an already existing (journal inside) ext3 FS ? Here's what I did to create a new FS with external journal for /dev/emcpowerl2 on /dev/emcpowerl2 mke2fs -O journal_dev /dev/sda10 mke2fs -J device=/dev/sda10 /dev/emcpowerl2 it works perfectly , but can I do the same whitout reformating the original FS; /dev/emcpowerl1 which is in

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

All, We are encountering spurious errors with ext3. After some period of heavy IO we may see messages similiar to: EXT3-fs error (device cciss/c0d0p5) in start_transaction: Journal has aborted When this happens the filesystem is remounted read-only. If it's the root filesystem the system becomes unresponsive and must be rebooted. An fsck on the affected filesystem shows lots of corruption.

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

Hi all, I'm trying to resize a journal on my root filesystem. This is Ext3, kernel 2.4.19, latest e2fsprogs + htree patch. I've remounted my root filesystem as ext2, but still when I 'tune2fs -O ^has_journal' I get ---- The has_journal flag may only be cleared when the filesystem is unmounted or mounted read-only. ---- So, how can I increase the size of the journal? I

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, I've just recently noticed that the ext3 projects is being actiavely maintained (again?). And looking at the new pages for 2.4.x it really made me interested. But I've got a few small questions I'd like to clarify before I start to use it. 1) Tune2fs and mke2fs talk about a "default journal size" that is depending on the partition size but don't give
