I had sent email to Andrea asking him if his blkdev-in-pagecache might cause the recent reports about ulimits being applied to block devices. This is his response which he asked me to forward to ext3-users since he can't post being a non-subscriber BTW, Redhat should whitelist various kernel hackers email address on their mailserver so that they can post freely to various lists Regards,

postfix-users seems to be a subscription only list. I'd recommend incorporating TDMA <http://tdma.sf.net/> to allow for easy discussion by outsiders Andrew Morton (of ext3 fame) had sent this message to postfix-users list I am forwarding so that Wietse can hopefully provide the definitive answer to the question Andrew Morton/Stephen Tweedie seek ----- Forwarded message from Andrew

I asked Ted about his patch for ext3 and ext2 and this is his response. I am not sure if his post will reach lkml since it's sent to vger.rutgers.edu IMHO, With the amount of work Andrew has done to make ext3 usable for MTA applications, Ted's work would make ext3 even better for MTA apps sinc both Postfix/qmail use 'find' in their control-scripts and queue statistics program

Hi, I am using openssh 2.1.1pl4 on a Linux 2.2.16 box [RH 6.1 distribution], I was confused as to why when I telnet into that box, I get /usr/local/bin in my PATH but when I ssh into my box, /usr/local/bin is not in my PATH I modified /etc/ssh/sshd_config to have UseLogin yes and then when I try to ssh into that box, I couldn't. ssh -v showed the following debug: Requesting shell. debug:

Hi. I'm attempting to setup a box here to be a file-server for all my data. I'm attempting to resize an ext3 partition to demonstrate this capability to myself before fully committing to this system as the primary data storage. I'm having some problems resizing an ext3 filesystem after I've resized the underlying logical volume. Following the ext3 resize, fsck spits out lots

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

Postfix <http://www.postfix.org> does a chattr +S on its spool directory when it is installed on Linux. This is what is written in the postfix startup script -- # # LINUX by default does not synchronously update directories - # that's dangerous for mail. # if [ -f /usr/bin/chattr ] then CHATTR="/usr/bin/chattr +S" else CHATTR=echo fi -- Is this still required on ext3 ?

man chattr mentions the following [on RH 7.2] A file with the `i' attribute cannot be modified: it cannot be deleted or renamed, no link can be created to this file and no data can be written to the file. Only the superuser can set or clear this attribute The .journal file has the following properties ---i-d------- ../.journal As such, I am confused as to how data to the journal can

That seems to be the indication given by this webpage http://www.zip.com.au/~akpm/linux/ext3/ext3-usage.html However, default install of Redhat 7.2 setsup fs_passno(6th field of /etc/fstab) as 2 which asks you if you want to run fsck after an unclean shutdown The question is, is fsck required after an unclean shutdown or should one just rely on journal replay. What does fsck do when it sees an

Hi, I installed RH 7.1/e2fsprogs 1.22 and util-linux 2.11f on a box with a 3ware 6200 and 2 20GB IDE drives and then installed 2.4.7 and ext3 0.9.5 I unmounted all the filesystems except / and did a tune2fs -i 0 -c 0 -j <device> on all the remaining filesystems This created a journal with a hidden file. >From what I recollect, doing a tune2fs on a mounted fs creates .journal file. I

Hi, I have the following line in $HOME/.ssh/config Protocol 2,1 I run OpenSSH 2.3.0p1 on my RH 7.0 box running 2.2.18. I am trying to ssh into a FreeBSD 4.2-stable box which runs OpenSSH 2.2.0. The account I am trying to ssh into has two files in $HOME/.ssh authorized_keys and authorized_key2 which contains RSA and DSA keys respectively. >From my RH 7.0 machine, I do the following ssh -v

Hi, I am using Redhat 7.3 which comes with openssh 3.1p1. I am running an antivirus software called vexira on this server. It starts of 2 daemon processes in the background. Whenever I stop/start these daemons in an ssh session, it hangs. I added "shopt -s huponexit" (without the quotes) in /etc/bashrc, but the hangs still occur. Any advice on this would be appreciated Regards, Yusuf

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

A playback of a mono vorbis track on a system using the i810 audio driver via ogg123 results in a double speed playback (chipmunk sound). It seems that this chipset doesn't support mono and while xmms seems to compensate for it, ogg123 doesn't I have a bugzilla report at redhat.com filed on this with more details https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=90433 Regards, Yusuf

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

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

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
