similar to: [PATCH] daemon: Parse /proc/mounts instead of /etc/mtab

I'm currently testing this patch on Rawhide, F14, Debian and Ubuntu. It's required to fix Rawhide at the moment, so I'm going to add this patch to the Rawhide SRPM. An alternative fix would be to change the daemon to always parse '/proc/mounts'. I'm not really sure which is better.

RHEL 5's old parted didn't have the -m option. A number of commands relied on this option and thus would break on RHEL 5: https://bugzilla.redhat.com/show_bug.cgi?id=598309 This rather large patch adds a second parsing path which allows us to parse the old text-based output (it preserves the code for parsing the output of the -m option too, since if supported, that is more accurate).

Hello, we recently had a big problem with a very high load on our linux (Sles11 SP3) samba server version 3.6.3. We experienced a system load of up to 90 for 300 active samba users. The result was that hardly any user was able to really do anything (eg access a file via samba). One sympton was visible in a very high share of cpu *system* time (about 25% on each of the 10 CPUs). This system load

Recently we changed the daemon so it builds guestfs_protocol.o by this rule: $(libsrcdir)/guestfs_protocol.o: force $(MAKE) -C $(libsrcdir) guestfs_protocol.o guestfsd_LDADD = \ $(libsrcdir)/guestfs_protocol.o \ #... The problem with doing this when building on Windows is that the toplevel src/ directory will be configured differently from the daemon/ directory. This means that

Hello everyone, It seems like we have a corrupted /etc/mtab file and I just wanted to check that my plan of action is correct. df -k returns: df: cannot read table of mounted file systems: No such file or directory ls -la mtab: ?--------- ? ? ? ? ? mtab messages full of errors: EXT3-fs error (device cciss/c0d2p1): ext3_lookup: unlinked inode 847444 in dir #846977 I

I had a go at writing a patch, but I think it's possible already without any patch. After launch you can get the PID of the qemu subprocess: guestfs_get_pid (g); --> returns PID You can use Linux to map this to a list of thread IDs: ls /proc/$PID/task/ --> returns a list of thread IDs [Yes, this is potentially racy, but in reality qemu has already started up fully after

The more I look at this patch, the less I like it. I would summarise why I think it's wrong here, but it's better if you look at the message I posted on the gnulib mailing list here first: http://lists.gnu.org/archive/html/bug-gnulib/2009-11/msg00434.html Directly accessing errno on Windows is wrong: you won't see the true reasons for an error by doing that. However depending on

supermin needs to download packages (eg. RPMs) when preparing the appliance. 'dnf download' finally appears to have made parallel downloads reliable[1]. Better late than never. So I have experimentally switched Rawhide's supermin to use 'dnf download' instead of the (deprecated) 'yumdownloader' program. This only affects the 'supermin --prepare' phase, which

I think there's some demand internally for a version of libguestfs where the appliance part actually runs on Windows. So I'm creating this thread to discuss the issue. The reason to want a Windows appliance at all is twofold: (1) better support for NTFS filesystems and Windows-native filesystem features (attributes, volume management etc), and (2) so we can run Windows CMD.EXE commands

This requires changing the generator so it can handle passing optional arguments all thr way through to the daemon, changing the protocol (see previous patch set), and implementing the new mkfs-opts call. At the moment there is just an optional blocksize argument, thus mimicking what you can already do with 'mkfs-b'. But this change will allow us in future to encode much of the rest of

Ran into a confusing situation today. When I mount an xfs filesystem on a server running centos 5.4 x86_64 with kernel 2.6.18-164.9.1.el5, the barrier/nobarrier mount option as displayed in /proc/mounts is always set to "nobarrier" Here's an example: [root at host ~]# mount -o nobarrier /dev/vg1/homexfs /mnt [root at host ~]# grep xfs /proc/mounts /dev/vg1/homexfs /mnt xfs
