similar to: ext3 htree upgrade

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):

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. Close reading of the 2.4 changelog suggests that htree isn't in there - only a patch to prevent non-htree

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

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 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?

Hi, I stumbled on the dir_index option of recent ext2 implementation which would be interesting for our mailservers (running dovecot with maildir) and found out that the newer ext2progs are able to cope with it; the 2.6 kernels do also but for the 2.4 kernels I still require a patch. Is that correct? Which patch would be the correct one to apply to the current 2.4.27 kernel ? Can anybody

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 enabled dir_index on a filesystem and dumpe2fs -h also reports this. My understanding is that this will be used for newly created directories and that old directories can be indexed using "fsck.ext2 -D". Two questions: - Is there a way to tell is a given directory is indexed or not? - Is there a better way to index the root fs than to boot off a live CD? Best, Norbert

I've been thinking recently that we should re-enable DIR_INDEX in mke2fs by default. When it first came out, we had done this and were bitten by a few bugs in the code. However, this code has been in heavy use for several thousand filesystem years in Lustre, if not elsewhere, and I'm inclined to think it is pretty safe these days. Likewise, RHEL/FC have had RESIZE_INODE as a standard

Hi I have mailed about this previously, but back then it was not really confirmed, so I have let it be at that. Anyhow, problem is that for some reason 2.5/2.6 ext3 with HTREE support do not like what perl-5.8.0 does during installation. It *seems* like one of the temporary files created during manpage installation do not get unlinked properly, or gets into the hash (this possible?) and cause

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.

I hope this is the right list. I have created an ext2 filesystem and removed the dir_index feature. I don't know if this kind of experimentation is going to help me learn something about filesystems or not. Well what is dir_index? Then I ran e2fsck -f -v -pD and the /dev file. Now what did I remove? Htree. I guess it can always be put back and it's on an experimental filesystem.

I have an ext3 filesystem that has several directories and each directory gets a large number of files inserted and then deleted over time. The filesystem is basically used as a temp store before files are processed. The issue is over time the directory scans get extremely slow even if the directories are empty. I have noticed the directories can range in size from 4k - 100M even when they are

Hi, I've run many time e2fsck, but in a special dir ls tells me: ls: r?cksendung-wlan.dvi: No such file or directory ls: baf?g_r?ckmeldung.latex: No such file or directory ls: finpr?f.pdf: No such file or directory $ cat finpr?f.pdf cat: finpr?f.pdf: Datei oder Verzeichnis nicht gefunden I don't know what to do? How can I find the failure? If I cat the files with debugfs, I see the

Hello, How to upgrade existing ext3 partition to new features? Moved from RHEL3 to RHEL4. I had to install from c0d0p6 so partition could not be reformated during install.

This may or may not be ext3 related but I am trying to find any pointers which might help me. I got a number of HP Proliant DL380 g5 with a P400 controller and also two qla2400 cards. The OS is RedHat EL4 U5 x86_64. Every time during reboot these systems panic after the last umount and I believe before the cciss driver is getting unloaded. The last messages I am able to see are: md: stopping
