[PATCH -v2 0/3] jbd2 scalability patches
This version fixes three bugs in the 2nd patch of this series that caused kernel BUG when the system was under race. We weren't accounting with t_oustanding_credits correctly, and there were race conditions caused by the fact the I had overlooked the fact that __jbd2_log_wait_for_space() and jbd2_get_transaction() requires j_state_lock to be write locked.

Questions regarding journal replay
Today, I had to uncleanly shutdown one of our machines due to an error in 2.6.28.3. Durin the boot sequence, the ext4 partition /home experienced a journal replay. /home looks like this: /dev/mapper/volg1-logv1 on /home type ext4 (rw,noexec,nodev,noatime,errors=remount-ro) Filesystem Size Used Avail Use% Mounted on /dev/mapper/volg1-logv1 2,4T 1,4T 1022G 58% /home Filesystem

[PATCH 2/3] jbd2: Remove barrier feature conditional flag (or: always issue flushes)
As part of migrating the FLUSH/FUA knob to the block layer, remove the journal flags and various conditionals in jbd2 that surround flush issue calls in favor of always issuing the flush. The block layer will handle gracefully the situation where a FLUSH or FUA request is issued to a device that doesn't support it. Signed-off-by: Darrick J. Wong <djwong at us.ibm.com> ---

Ext3 Performance Tuning - the journal
Hello, I have some performance problems in a file server system. It is used as Samba and NFS file server. I have some ideas what might cause the problems, and I want to try step by step. First I have to learn more about these areas. First I have some questions about tuning/sizing the ext3 journal. The most extensive list I found on ext3 performance tuning is

More external journal woes.
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

journal file exists but feature missing
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

/.journal ext3 on a flash
Hi, I'm formatting a flash with ext3, but I need to move the journaling file (/.journal) in the flash to prevent it's corruption. In previous message I read that it's possible (https://www.redhat.com/archives/ext3-users/2004-March/msg00009.html), but I can't find any /.journal in my ext3 fs. How can move the journaling file in the flash without /.journal file?? Thanks

Ext3 -> Ext2 ?
Hi there, I tried to setup my linux box with an ext3 root file system. That failed because of wrong initrd settings. Sorry. Now the filesystem is marked having a journal but there is no /.journal file anyway. I tried to buikd that journal by hand (tune2fs -j /dev/hda3 - in my case). That fails also. :-( /sbin/tune2fs -l /dev/hda3 says: ... Journal UUID: <none> Journal

Question about Journaling Root Filesystem.
I am trying to use data=journal on my root file system. I have separate slices on which journal=data works fine on all of them, except root. I have tried putting rootflags=journal=data on my kernel line in Grub, but I get a kernel panic. I'm missing something simple, I jut know it. It can't be the kernel version because it works on the other slices. My etc/fstab file is as follows:

External journal on flash drive
Hi, I'd like to use a flash drive as a journal device, with the purpose of keeping the main disk drive spun down as long as possible. I have a couple of questions: 1) Does the journaling code spread write accesses to the journal device evenly, as I hope, or are there blocks that are particularly "hot"? I.e., do I have to worry about the flash device dying quickly because of

removing external journal
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

Ext3 Journal corruption on hitachi deskstars
I recently came across an enormous cluster of x86 clone machines running fedora core 1 (2.4.24) which have typically all intel or amd have VIA IDE chipsets. They frequently experience corrupted journals rendering the ext3 partition in read-only mode. More important than recovering the filesystem, I am interested in finding the root of the problem. The common hardware that all of these

[PATCH 1/2] JBD2: Allow feature checks before journal recovery
Before we start accessing a huge (> 16 TiB) OCFS2 volume, we need to confirm that its journal supports 64-bit offsets. So we need to check the journal's feature bits before recovering the journal. This is not possible with JBD2 at present, because the journal superblock (where the feature bits reside) is not loaded from disk until the journal is recovered. This patch loads the journal

[PATCH 1/3] jbd2: Fix possible NULL pointer dereference in jbd2_journal_begin_ordered_truncate()
If we race with commit code setting i_transaction to NULL, we could possibly dereference it. Proper locking requires journal pointer (journal->j_list_lock) we don't have. So we have to change the prototype of the function so that filesystem passes us the journal pointer. Also add more detailed comment about why function does what it does how it should be used.

Ext3 and external journals...
Hi, I am trying out ext3 with an external journal (on a battery backed RAM card). I use data=journal, and sync nfs writes go nice and fast :-) But.. I had to power cycle it (buggy VM.. grumble :-) and now I cannot get my filesystem back. It is only a test filesystem so I don't need the data. But I want this to work before I put real data on it. If I "fsck /dev/md1", it

e2fsprogs 1.23 problem handling 2.2 version 1 format journals
Just fired up a test machine on its first 2.4 kernel - specifically 2.4.9-ac16 (includes ext3 0.9.6). Had also upgraded e2fs tool set to 1.23. This box has previously had 2.2 kernels with Stephen's ext3 patches, and looks like it was last rebuilt from scratch in early March. I suspect it may have an old version 1 format journal on the filesystems. [Unfortunately I managed to destroy the
