Hi,
I backup (simfs) containers nightly using vzdump (with suspend).
Early this morning one of the backups failed with the following error:
INFO: Error: unsupported deleted submount:
(deleted)/var/named/chroot/etc/named.rfc1912.zones
I have had this problem before and know it is caused by a bind update
not deleting some chroot mounts.
df shows:
df: ` (deleted)/var/named/chroot/etc/named.rfc1912.zones': No such file
or directory
df: ` (deleted)/var/named/chroot/etc/named.iscdlv.key': No such file or
directory
df: ` (deleted)/var/named/chroot/etc/named.root.key': No such file or
directory
Filesystem Size Used Avail Use% Mounted on
simfs 6.0G 1.3G 4.8G 22% /
none 512M 4.0K 512M 1% /dev
none 512M 0 512M 0% /dev/shm

simfs 6.0G 1.3G 4.8G 22% /var/named/chroot/usr/lib64/bind
This is easy to fix:
umount /var/named/chroot/etc/named.rfc1912.zones
umount /var/named/chroot/etc/named.iscdlv.key
umount /var/named/chroot/etc/named.root.key
Does anyone know if this is a problem with openvz or vzdump?
Here are the log messages around the error:
INFO: first sync finished (172 seconds)
INFO: suspend vm
INFO: Setting up checkpoint...
INFO: suspend...
INFO: Can not suspend container: Invalid argument
INFO: Error: unsupported deleted submount:

INFO: Checkpointing failed
ERROR: Backup of VM 550 failed - command 'vzctl --skiplock chkpnt 550
--suspend' failed with exit code 16
RPM Versions:
vzdump-1.2-4.noarch
vzctl-4.9.4-1.el6.x86_64
vzctl-core-4.9.4-1.el6.x86_64
vzkernel-2.6.32-042stab113.11.x86_64 (latest kernel installed but not
rebooted yet)
Thanks
