[pve-devel] VZDump issues with lvm

[Adrian Almenar]

Hi everyone,

Last days, im having a really strange issue. I have some vz containers, and they are backuped every day at 3 AM.

The task was created using proxmox web interface (Simple as All VMS) option. (Backup is made on an external disk (USB 3.0), mounted in /media/backups)

Today (this is the second time that happens) i find my root partition totally full, checkout the logs and it was file by the kern.log file.

The error printed constanty is:

ext3_orphan_cleanup: deleting unreferenced inode 25846833
ext3_orphan_cleanup: deleting unreferenced inode 25846833
ext3_orphan_cleanup: deleting unreferenced inode 25846833
ext3_orphan_cleanup: deleting unreferenced inode 25846833
ext3_orphan_cleanup: deleting unreferenced inode 25846833
ext3_orphan_cleanup: deleting unreferenced inode 25846833

(Yes it’s always the same inode)

There’s only a process locked by this:

mount -n -t ext3 /dev/pve/vzsnap-nodename-0 /mnt/vzsnap0


I have tried forcing the lvmremove (But all i get is a lock):

# lvremove --force /dev/pve/vzsnap-nodename-0

  Unable to deactivate pve-vzsnap--nodename--0 (253:2)
  Unable to deactivate logical volume "vzsnap-nodename-0"


Also, tried to use dmsetup to unmount the volume using:

dmsetup remove -f --retry /dev/pve/vzsnap-nodename-0

But command still does not return anything.

Here i include pvevefsion —verbose for more information:

I have search the forums, also on openvz.org bugzilla but haven’t found anything.

Any thoughts ?
