similar to: New htree patches?

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

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

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

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, i've made *some* benchmarks, i plan to do more. benchmarks requests welcome, e.g. "please test this...with that.." https://ephigenie.kicks-ass.net/bench/benchmark.html but only in https://ephigenie.kicks-ass.net/bench/prinz are results right now. I hope this is helpful. Thanks, Christian.

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 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

Over the last two days we've been seeing a fair bit of this: ---- # ls -laR > /dev/null ... ls: ./server2/b/user/bxyz/392.: Input/output error ---- This is with the latest htree patches applied to 2.4.19, and latest e2fsprogs-test, on a dual AMD system, with 5x73GB SCSI drives on a MegaRAID controller. We're using the gcc 2.96 that comes with RH7.3. esfsck shows "Inodes that

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, 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

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, Someone knows if the htree patch is applied in the last kernel for RedHat 8 (kernel-2.4.20-18.8) for the ext2/ext3 filesystems ? Greetings. --- Carles Xavier Munyoz Baldó carles@unlimitedmail.org http://www.unlimitedmail.net/ ---

Hello, I am trying to set up some Cisco 7940G phones with the 3com POE injectors. I have the 3CNJPSE24 power injector, this is the rackmountable 24 port injector. My question is does anyone know how to serial console into these things? I have tried just about every cable setup I can think of and baud rates but I can't seem to get anything out of it. I want to check to see what certain
