cs & gfs
by Jure Pečar 09 Dec '05

09 Dec '05

Hi all, I was informed[1] that gfs & rhcs packages are in the works but that there are some problems with the code. What are these problems? Can we do anything to help test / solve them?

gdm-restart/gdm-safe-restart
by Kanwar Ranbir Sandhu 09 Dec '05

09 Dec '05

Hi all, On a CentOS 4.2, x86_64 system, I created a new session that is selectable from the sessions list in GDM. To make GDM see the changes, I ran the following: gdm-safe-restart That's supposed to make GDM re-read it's config files. Well, it worked, but instead of staying on vt7, GDM moved to vt9. At first it looked liked GDM had died, but I ran ps aux|grep gdm, and found it running on vt9. Odd, that. I then tried a gdm-restart, and GDM disappeared again. It had moved to vt10. Odder, still. I was only able to get GDM to restart on vt7 by killing the GDM process, or by changing the server's run level from 5, to 3 and back to 5. On a CentOS 4.2, i386 box, gdm-safe-restart and gdm-restart function as I expected them to: GDM restarts and stays on vt7. I also didn't notice any problems on a FC4 box. There isn't much of anything in terms of documentation on gdm-safe-restart and gdm-restart. I'm fairly sure I'm using them correctly. Anyone else notice this behaviour?

Query: Filesystems
by Maciej Żenczykowski 08 Dec '05

08 Dec '05

Hello, Just a few quick, but not very simple questions...: Do any Linux filesystems (besides XFS) support freezing? (ie. in conjuction with LVM snapshots this can allow a mounted filesystem to be frozen [freezing all processes writing to this filesystem] in a valid state (with possibly dangling unlinked files), the device can be snapshotted via LVM, and the original filesystem unfrozen - the snapshot now contains a valid snapshot in time of the original filesystem - with no corruption. Can this (freezing) be used for the root filesystem or other important filesystems? ie. might it cause something vitally important to freeze? Can a snapshotted LVM (the snapshot, not the original filesystem) be modified (I assume snapshots are purely readonly...) - so as to remove the dangling deleted/unlinked files and possibly modify the uuid (I realize there is a nouuid mount option for XFS). And the last question: is there some sort of filesystem which supports generating 'in-filesystem' snapshots (ie. some sort of copy-on-write block semantics applicable both to files and directories combined with both a root rw directory to access current files and a ro /snapshot/YYMMDD-HHMMSS hierarchy to access snapshots from past dates with the possibility of deleting them at will (ie. generate a snapshot every hour, after 24 hours leave only every 6th one, after 7 days leave only dailies, after a month leave only weeklies etc... - much too complicated, but it's easier to get the basic idea across on a larger example - probably organized via cronjob). I realise such a solution would not be foolproof (if the disk goes bad or the filesystem goes haywire it's pretty much useless) so a hard-copy would still need to be maintained (probably via freeze/snapshot/unfreeze/dump it somewhere else) - but this would be useful for the users (the ability to restore past deleted files...) In a way this could possibly be realized via some twidling with rsync (although for space efficiency this would require copy-on-write hardlinks or something like that) but I see no way of doing this without wasting a lot of space (at least 1 copy of the snapshoted filesystem, the rest could probably be hardlinked). And to maintain full R/O status, this would need to be a seperate partition, etc... Any comments/ideas? Cheers, MaZe.

What is going on with the USB that it will not boot in normal mode? Install booted and installed normally, linux rescue booted (although I still saw messages about disabling IRQ #11). I see that same message on a normal boot but it never continues after that... Any ideas, why USB is stopping this laptop from booting? Jerry

x86_64 kernel compilation
by John Logsdon 08 Dec '05

08 Dec '05

If I can squeeze a message between the discussions on security (:-)) I have been trying to compile a kernel on an x86_64 box under CentOS4.1 and now 4.2. The problem is that neither make xconfig or make gconfig work: make gconfig * * Unable to find the GTK+ installation. Please make sure that * the GTK+ 2.0 development package is correctly installed... * You need gtk+-2.0, glib-2.0 and libglade-2.0. * make[1]: *** [scripts/kconfig/.tmp_gtkcheck] Error 1 make: *** [gconfig] Error 2 and a similar message for xconfig: make xconfig HOSTLD scripts/kconfig/qconf /usr/bin/ld: cannot find -lqt collect2: ld returned 1 exit status make[1]: *** [scripts/kconfig/qconf] Error 1 make: *** [xconfig] Error 2 Yet I have the following libraries installed: compat-glibc.i386 1:2.3.2-95.30 installed compat-glibc.x86_64 1:2.3.2-95.30 installed compat-glibc-headers.x86_64 1:2.3.2-95.30 installed glibc.i686 2.3.4-2.13 installed glibc.x86_64 2.3.4-2.13 installed glibc-common.x86_64 2.3.4-2.13 installed glibc-devel.x86_64 2.3.4-2.13 installed glibc-devel.i386 2.3.4-2.13 installed glibc-headers.x86_64 2.3.4-2.13 installed glibc-kernheaders.x86_64 2.4-9.1.98.EL installed glibc-utils.x86_64 2.3.4-2.13 installed gtk+.i386 1:1.2.10-33 installed gtk+.x86_64 1:1.2.10-33.centos4 installed gtk+-devel.x86_64 1:1.2.10-33.centos4 installed gtk-engines.i386 1:0.12-6.el4 installed gtk-engines.x86_64 1:0.12-6.el4 installed gtk2.x86_64 2.4.13-18 installed gtk2.i386 2.4.13-18 installed gtk2-devel.x86_64 2.4.13-18 installed gtk2-engines.x86_64 2.2.0-7.el4 installed gtk2-engines.i386 2.2.0-7.el4 installed libglade2.i386 2.4.0-5 installed libglade2.x86_64 2.4.0-5 installed pygtk2.x86_64 2.4.0-1 installed pygtk2-libglade.x86_64 2.4.0-1 installed Since menuconfig is totally unusable, I am quite stuck. I have regularly compiled on an x86 box with virtually identical installation and I have compared the libraries but can't see what I have missed. The kernel version is 2.6.14.3 which is the latest stable but this happens with older kernels. There have been suggestions of various patches to a makefile which I have tried but to no avail. So I think it may be a library issue. So can anyone with an x86_64 box on which they have successfully compiled a kernel post me their output from: yum list | egrep gtk\|glibc\|glade | grep installed ... or even the complete yum list (privately to save bandwidth!)
