There's a new set of ext2/3 patches for 2.4.21-pre5 available at: http://thunk.org/tytso/linux/extfs-2.4-update/extfs-update-2.4.21pre5-2 and in broken out form at: http://thunk.org/tytso/linux/extfs-2.4-update/broken-out-2.4.21pre5-2 New to this patch set include: * A kludge to help htree work well with Linux's NFS implementation * Allow the orlov allocator to be disabled via a

Hello, Could someone create some newer htree patches for the 2.4.x kernel? There are some bug fixes in the 2.4.21-rc releases that would be nice to have but the htree patches preceed those and they won't apply cleanly to later pre/rc kernels. It sounds like Marcelo may be about ready to put out 2.4.21 so it may just be worth holding off until that happens, but I don't suspect much will

I've backported all of the bugfixes to the 2.5 dxdir/htree patches to 2.4, and have created a new set of patches for Linux 2.4.21rc5. At this point it *looks* like we've fixed all of the htree bugs that people have reported, including the brelse bug, the memory leak bugs, and the NFS compatibility problems. I've done *very* light testing, and things seem to work, but I'm now

Apologies for the newbie question: I have a (stock) 2.4.20 build (*not* -ac), and I'm trying to work with large ext3 directories. By large, I mean 160,000 files per directory. (Yes, I know it would be better in nested directories but such is life). I feel htree would benefit me. Having upgraded from an earlier version of 2.4, I don't see any change, and close reading of the 2.4 changelog

Guys, I have recently applied the latest 2.4 htree patch on a heavily loaded nfs server. The nfs server serves around four very busy clients that deliver email in maildir format and pop3/imap clients. Being maildir I presumed that the htree patch would improve performance - but I was wrong. Load on the server went up by around 25-40%. After 3-4 hours of heavy use the clients load went up to

Hi Guys, I am running ext3 on kernel v2.6.5. I have an ext3 filesystem with dir_index and data=journal for /var/spool/exim Today I noticed in the exim logs a bunch of 'failed to unlink /var/spool/exim/input/P/1BRbSP-0006hy-Jp-D' I also noticed these in the kernel logs: EXT3-fs warning (device hda12): ext3_unlink: Deleting nonexistent file (612870), 0 EXT3-fs warning (device hda12):

Hi Guys, I have experienced a recent performance issue with an ext2 filesystem. Essentially I have had several files that get overwritten on average once per day. This has been happening for about a hear when the program accessing and reading those files started from several milliseconds to 15-20 seconds to open and read the file. Moving the directory to a new name and copying the contents

Hi Guys, I am planning on upgrading an existing NFS exported filesystem to the ext3 htree patch on kernel v2.4.23. Will the patch index directories automatically after tune2fs -O dir_index or should I do an e2fsck -Dfy on the filesystem before remounting?

Hi, Just thought I'd share some test results of mine in case anyone is interested. Basically the tests are siumulating what our product does with files - although the tests do it a lot quicker (not as many files though). The test is to create 1 million files (each containing the text of the file number) spread over a number of directories. The files are then removed in the same manner as

Well here is what I got from testing htree with NFS. http://labs.zianet.com/benchmarks_html/postmark_benchmarks_NFS_100_htree.html It looks like htree improves performance when the storage device is local(as per my previous post) but it looks like htree degrades performance when used in conjunction with NFS. I am going to try it with gigabit ethernet when I get the time to see if maybe I am

I decided that I would try out 2.5.44, and I noticed that htree was merged. If I don't do the tune2fs -O dir_index, and e2fsck -D, the (exisintg) fs won't use htree, right? Once I do the tune2fs and e2fsck, will I still be able to go back to a non-htree kernel if needed? (Will a htree-ized fs work on a non-htree kernel?) I'm guessing that it won't. I've seen a 2.4 htree

I just booted 2.5-bk current as of last night with the below patch¹ (which was recently posted to ext3-users) that un-static-ifies a struct dx_frame in namei.c. I then did my best torture test for the brelse bug: starting gnus (3600+ nnmh folders² with a total of XXX messages; it does a readdir on each of those folders) while doing bk consistancy checks in 2.5 and/or 2.4 kernel trees. All

hi, i have a tricky situation here and and don't know where to start with the solution. i happened to set up a linux system, but i had to install the base system on another machine. i used e2fsprogs 1.30-WIP (30-Sep-2002) for this. now the machine is up and running, but i have to use e2fsprogs 1.27 (8-Mar-2002). it's a debian system and i wanted to stay sane & stable, hence using

Just looking through the 2.4.20pre changelogs, I see there's been a bunch of Ext3 patches since 2.4.19. I'm keen to take advantage of any bug fixes and performance improvements, but am nervous about using 2.4.20 until it's completed its release cycle. Is there any way to get a patch just containing the Ext3 changes? Are there any changes since 2.4.20 that are very important, either

My reading of the kernel.src.rpm doesn't indicate that Severn has ext3 htree patches. Stephen, were there any issues seen during Cerberus testing ? Regards, Yusuf -- Yusuf Goolamabbas yusufg@outblaze.com

I post a patch for comment on ext2-devel for the NFS cookie bug. Did not get any feedback yet. As Ted suggested, it set the cookie to -1 on EOF, even though it is not seek able to there. I only test it with Stephen's "readdir.c". Not have chance to run it on a NFS server yet. Do you have more information about the cache trashing bug? Regards, Chris ===== dir.c 1.5 vs edited
