Greetings, Yesterday I had the need to remove the drives that make up my /vz partition and replace them. I basically stopped all containers and then rsycn'ed the private dirs to a separate drive, got the new drives installed, and then copied the container's filesystems back over. I do have one container I'm having a problem with. It will run for a while and then give disk errors and go read-only. How does one fsck the disk image of a container? And yes, it is ploop-based. Below are some sample error messages I see in /var/log/messages on the host: Nov 7 08:40:34 ovz kernel: [53378.803703] CT: 202: started Nov 7 08:40:36 ovz kernel: [53380.273006] ploop_set_error=-5 on ploop49691 Nov 7 08:40:36 ovz kernel: [53380.277608] EXT4-fs error (device ploop49691p1): __ext4_get_inode_loc: unable to read inode block - inode=6422529, block=25690144 Nov 7 08:40:36 ovz kernel: [53380.286925] Aborting journal on device ploop49691p1-8.

Yes, I do have fairly recent backups... and I've already tried copying the container's filesystem from the directory-based backup three times... but it eventually gives me errors after running a while. Is this a sign of underlying disk issues... or is there a way I can fsck and get the disk happy again? Help!
