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

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:

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

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,

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. 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

Following the announcement on lkml, I have started using ext3 on one of my servers. Since the server in question is a farily security-sensitive box, my /usr partition is mounted read only except when I remount rw to install packages. I converted this partition to run ext3 with the mount options "nodev,ro,data=writeback,defaults" figuring that when I need to install new packages etc,

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, I was wondering if anybody was using a UMEM <http://www.umem.com/> NVRAM card [the MM5415 family] as an external journal for ext3. According to the help text in 2.6.7 config, it doesn't have a major number assigned so it chooses one dynamically. It suggests to use 'devfs' (which I thought was deprecated in 2.6.x) or look in /proc/devices. I was wondering if anybody was using

According to this page, http://www.apple.com/macosx/technology/unix.html In addition, Java, Ruby, Python, and Perl have been extended to support DTrace, providing unprecedented access for monitoring the performance characteristics of those languages. When I do dtrace -l | grep -i perl on MacOSX 10.5.2. I don''t see any perl providers so I am not sure how I could monitor perl scripts via

Hi, I tried to convert my root partition from an ext2 to ext3 fs using tune2fs. I'm running a 2.4.10 kernel with ext3 support, but the partition is not mounted ext3. In fact the journal feature is missing from the superblock: # cat /proc/filesystems | grep ext ext3 ext2 # tune2fs -l /dev/hda6 | grep features Filesystem features: filetype sparse_super # ls -l /.journal

A friend of mine made the following comment in a discussion I had with him that on a website we adminster we should offer a) WAV or maybe shorten files b) Ogg as a decent reference lossy encoded version He's been trying to convince me that we should offer MP3 (in lieu of WAV) and possibly Ogg. The audio files are primarily vocals I am not a physics guy but his statements don't

Hi I'm experiencing some problems on a harddisk (it has crashed for no known reason), and in pursuit of getting some of the data out of the disk I'm learning to use the e2fs progs package. Origianlly I used version 1.38, but after experiencing segfaults in e2fsck -which now is solved, I upgraded to 1.39, but now I have hit another problem (on another partition): The partition was
