From: Linda Walsh on 4 Feb 2010 22:50 I don't know if this was present (maybe not?) when the script was written, but the script for taking a snapshot in the instructions for shadow_copy: that looks like this: ---- xfs_freeze -f /home/ lvcreate -L10M -s -n $SNAPNAME /dev/Home/lvol0 xfs_freeze -u /home/ mkdir /home/shadow_share/@GMT-$SNAPNAME mount /dev/Home/$SNAPNAME \ /home/shadow_share/@GMT-$SNAPNAME -onouuid,ro ---- Causes an, apparently, well-known system hang when you do the lvcreate. The workaround is to NOT use xfs_freeze. I don't know if this is a kernel bug -- haven't gotten things tracked down far enough yet, but I can confirm that the above does cause a hard hang that eventually requires rebooting the system to unwedge everything. kernel = 2.6.27.29 from OpenSuse 11.1 Samba = 3.4.3-12 lvcreate from lvm2-2.02.39-8 The notes I read inidicated a problem in the kernel or maybe, more specifically the xfs in the kernel. Will have to check with xfs folks to see if they've heard of this... Have yet to sub to the lvm list...(TODO(byme): sub lvm list) -linda -- To unsubscribe from this list go to the following URL and read the instructions: https://lists.samba.org/mailman/options/samba |
