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 ?

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,

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

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:

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 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.

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

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

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.

We run a third party application that creates an inordinate amount of subdirectories in a single directory. To speed up I/O, I wanted to set the T attribute on the directory that will hold the subdirectories. The "chattr +T /usr/local/lepus-bb/a-0607" command returns status 0, but when I verify the setting, the attribute isn't there: # lsattr -d /usr/local/lepus-bb/a-0607

Enabling compression via chattr +c works with ZLIB (default method) only, right? Since there is no way to specify a compression method. Cannot I use LZO this way?

Hi list, I just noticed in the chattr(1) man page that there exists a 'j' attribute which actually does the same thing that data=journal mount option would do, expect it only sets this property on the directories of my choice. Big Thanks to the one that came up with that idea :) It allows me to set +j on mail queues that must sit on the same partitions as the rest of the system (the guy

What happens if you set an individual file inside a subvolume as nocow (chattr +C) and then take a snapshot of that subvolume and modify the file in both? Will btrfs now ignore the nocow attribute completely or will it do "as few copies as possible"? (I''d love to know if it''s possible to visualize the fragmentation of a single file.) -- To unsubscribe from this list:

[sent this to ext2-devel but haven't seen any other traffic there, so cc-ing it here] [Last week] while configuring a new box I came across a site suggesting: chattr -R -S +j +A /var/spool/postifx to improve postfix's speed on ext3, in lieu of mounting a separate fs there w/ data=journal. So I tried it. Both on the new box (2.4.21-7um) and on my laptop (about three csets shy of the

has anyone played with the securelevel variable in the kernel and the immutable flags in the ext2 file system? The only way I have found to change the flag is by patching sched.c from int securelevel=0 to int securelevel=1 The sysctrl code seems to allow the setting of the flag only by init (PID=1) and only upwards (0->1, etc). The problem is that I haven''t found a way to get init

Use the new non-coherent DMA API including proper ownership transfers. This includes adding additional calls to dma_sync_desc_dev as the old syncing was rather ad-hoc. Thanks to Thomas Bogendoerfer for debugging the ownership transfer issues.
