File system for large directories?
Hi, Our servers have to deal with huge amounts of small files (tens, sometimes hundreds of thousands of files IN ONE DIRECTORY). Currently they use ext3 but I wonder wether this is the prefered FS. I used to be fond of ReiserFS v3 until I got beaten by it not recovering from a partition resizing excercise. Trying to find the answer on the net I found: http://librenix.com/?inode=3296 (Circa 2003, recommends ReiserFS v4, which isn't in the mainstream kernel yet). and http://www.debian-administration.org/articles/388 (Circa 2006, recommends XFS). The later compared handling of large trees (i.e. not necessarily single directory with lots of files in it). Does anyone have good and up to date recommendations for such situation? The files are e-mail messages which are writen, transferred then deleted. I'm also thinking about better ways to handle the files (e.g. putting every few thousands of them in a .zip file to transfer, spreading them across a two-level directory tree etc) but I'd rathertry to keep the changes to the existing software and scripts the the minimum which is required to speed things up.

Ext3 is - last I chaecked (about two years ago) possibly the worst filesystem for dealing with LOTS of files in a single directory. Reiser 3 was very good (did not try reiser 4). However, I am very wary of reiser now - what with poor (or, maybe, not so poor) Hans being in jail, reiserfs may be going the way of the dodo. I'd run bonnie (just the creation/deletion tests) for JFS, XFS and Ext4 (which is starting to make an appearance here and there). IIRC - XFS is ALSO not very good with lots of small files. > I'm also thinking about better ways to handle the files (e.g. putting every > few thousands of them in a .zip file to transfer, spreading them across a > two-level directory tree etc) but I'd rathertry to keep the changes to the > existing software and scripts the the minimum which is required to speed > things up.

vixie-cron acting weird (actually not acting at all)
Hi All,
Sorry for being so verbose, but I was not really sure which of all those
details is important to understand the source of the problem :)
I've installed a new machine into production on Thursday (19 Apr 2007).
Machine is still running since then:
$ uptime
21:10:43 up 2 days, 10:11, 2 users, load average: 0.02, 0.04, 0.01
The machine is a Dual Core Xeon 3GHz. with HyperThreading enabled (so "grep
processor /proc/cpuinfo | wc -l" says "4").
Machine is running Gentoo Linux, with kernel 2.6.19-gentoo-r5, x86_64.
Now for my problem.
I installed the system with Vixie-Cron, and crond appears to be running. It
appears in the processlist, and it sits in the Ss state on ps. So far - very
normal.
According to the logs, until April 20th, 19:00, processes ran exactly when
they were defined to run (I have a process that runs every 15 minutes).
From 19:00 until 23:16:55 (note the 1 minute and 55 seconds after the round
hour quarter) - there is a complete silence in the logs.
It then resumed running with the same delta from the quarter hour until
00:02am on Apr 21. A bit later, I see that ntpd reports that ntp had no
servers available to sync (at 2:31am). Doesn't seem related, but I am
mentioning it anyways, as cron is, after all, time based.
Occasionally from that time I see Gentoo's run-crons acting at some hours,
like 2:50am, 03:07:17am (where is removes the lastrun of cron.daily and
04:26:15am where it ran cron.weekly). At 03:14:25am I also see ntpd
synchronized back against 192.43.244.18, stratum 1.
There is another run-crons at 05:40am, and weirdly enough, cron kicks back to
life at Apr 21, 07:45:41am, with my regular 15-minutes task, which it
executes once. Since then, silence until 09:00am where only CERTAIN tasks are
executed (and the every-15 minutes DOES NOT), and again silence until
17:16:13 where the every-15 kicks in, then it works at 17:33 and 17:46, and
since then, silence again.
I tried restarting cron at 20:51:27, the restart got logged. Didn't seem to
have any effect. on 21:20:31 I see a run-crons, yet the every-15 does not
work.
I tried stracing the crond process, and I got the following:
Process 6796 attached - interrupt to quit
stat("crontabs", {st_mode=S_IFDIR|0750, st_size=120, ...}) = 0

rt_sigprocmask(SIG_SETMASK, [], NULL, 8) = 0
nanosleep({30, 0},
I did the same strace on my cron at my computer at home, which appeared to be
sleeping for a different period (namely, 60), but this doesn't look so
important, as the sleep on my computer at home ends rather quickly and I see
many scans of crontabs, /etc/cron.d and /etc/crontab, which is normal
behavior, I guess.
So I am thinking there is something maybe wrong with nanosleep(). But what can
it be? My guess is related to time drifting due to all those CPUs, but in
that case, why did it work great in the begining?
I didn't try rebooting the machine, which might have solved the problem
(either temporarly or not), but wanted to try and solve it (or at least
understand the problem) before I might get it gone.
So, any hint from you guys will be greatly appreciated.

Re: vixie-cron acting weird (actually not acting at all)
Hi,
I think that your problem is in the crontab time and day configuration.
Can you send the relevant crontab time and date configuration.

Re: wmv player for redhat 9
Hi, WMV is a type of file, not a type of compression. You need both a WMV player and a CODEC (enCODerdECoder) for the types of compression. One codec for audio and one for video). Actually, like AVI, it's a container which supports different codecs. You can (theoritaclly speaking) wrap a Quicktime Movie inside a WMV file :) MPLAYER and VLC (www.videolan.org) both play WMV files, if the have the correct codec is at this time a guess. Depends which build/version you use. the SVN version of FFMPEG (the backend that both VLC and MPlayer uses) has a full native WMV7/8/9/VC-1 (microsoft's "HD") decoding support, so I guess that the latest mplayer/vlc (from their CVS/SVN trunk) do not require those DLL's to play the files. It might be needed for the latest release of MPlayer though. Thanks, Hetz -- Skepticism is the lazy person's default position.

Same goes for 'ps' - I look at the process start time, and every time I invoke 'ps', all the values go 32 minutes back and forth in time. I stopped ntpd and it is still happening so this is not the cause.

Ext3 is - last I chaecked (about two years ago) possibly the worst filesystem for dealing with LOTS of files in a single directory. Reiser 3 was very good (did not try reiser 4). However, I am very wary of reiser now - what with poor (or, maybe, not so poor) Hans being in jail, reiserfs may be going the way of the dodo. If Reiser3 is already in mainline and stable - wouldn't it be supported even if Hans/Nemesis vanishes? Reiser4 is not relevant because I want to stick to mainline kernels, much preferably Debian supplied kernels. I'd run bonnie (just the creation/deletion tests) for JFS, XFS and Ext4 (which is starting to make an appearance here and there). IIRC - XFS is ALSO not very good with lots of small files. Will try to do that, though again - if ext4 isn't in the mainline yet then it's not relevant for me.

B-sort em? Switch the back-end to database (assuming the blobs are small)? I'm thinking of databases sometimes (the files are around 4k on average) but it feels like Hans Reiser was sort of right about that - a filesystem can be used as a database for this sort of data.

Do you access them locally or remotely, if so, how? They are writen locally, then transferred over FTP to Windows machines. I used to be fond of ReiserFS v3 until I got beaten by it not recovering > from a partition resizing excercise. Resizing a partition is not a good indicator. There are too many other factors involved. I just became worry of the admin tools available for ReiserFS. It's wonderfull when everything is dandy (and survived many power failures at my previous home) but then when I needed to do something else, which I hear is trivial with ext3 for instance, it failed measerebly. Benchmark your own environment. Hardware specs (RAID, RAM, CPU, etc) can tilt the results. Repeat the benchmarks for about 3-5 time. I like Bonnie++. Look for the results that best match your environment (Read, Write, Create, etc). It looks like Bonnie++ is what everyone and his dog are doing. I'll try to see how can I do that (hardly any headroom in terms of spare hardware to shift things around). Cheers, --Amos

OX and Egroupware go beyond that: Project management, DMS, Wiki, discussion groups, linking, etc. Zimbra has Zimlets, which can offer similar functions. OK, so just to clarify this - sounds to me like Scalix provides the same functionality as Exchange, isn't it? I understand how the other features could be useful for group cooperation, but my main focus is finding a replacement for Exchange that Outlook users can live with (with hope that one day I'll be able to get rid of it in my office). PS - what's "linking"? Thanks. --Amos

May be you have ntpdate running ? ntpd by itself don't change time, but ntpdate did. You can disconnect your box from the network and check again how tine behave.
