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

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

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'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

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

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

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

...mail on ext3-users about a year ago reporting a similar problem: https://listman.redhat.com/archives/ext3-users/2002-October/msg00053.html I don't know if it was fixed. In my code, I'm using only vfs calls and do nothing that is specific to ext3. This works fine on ext3 and ext2 without HTrees, but this behavior occurs on ext3 with Htrees. Here's a high level description of what I'm doing in versionfs_unlink: * down the isem of parent directory * compute the name of the version file * lookup the name using lookup_one_len * create the version'ed file using vfs_create *...

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, Searching in the ext3 filesystem mailing list I have seen that there is an indexed directory extension for it. Is this extension stable code ? Has anyone test it ? How may I obtain and install it ? Is it available in any of the last kernel releases ? Greetings. - --- Carles Xavier Munyoz Baldó carles@descom.es Descom Consulting Telf: +34

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?

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

Hi Guys, I am quite keen to try out the new htree extensions to ext3 however I wish to use them under NFS. I have noticed comments from the developers saying that it doesn't work properly under NFS. What exactly is the current status of the issue?

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

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):
