You could wrap the tar -czf ... in a systemd unit and add a systemd drop-in configuration for whatever service that needs /var/lib/pve-cluster (I guess it's just pve-cluster.service) containing something along the lines of
[Unit]
Requires=the-tar-backup.service
After=the-tar-backup.service
Re: Similar problem
I can confirm that 2.6.32-96 is still affected (at least the oops). I am unsure if I can upgrade to 3.0 - is 2.6.32-95 compatible with pve 3.0 ?
Re: Similar problem
I would presume that this issue will be fixed when the RHEL 6.4 kernel flows downstream (through OpenVZ) to proxmox. I'm still running on 2.6.32-12-pve, but I'll check -17 to see if it fixes the issue for me. If so, perhaps it will be possible to see what caused the...
Re: Similar problem
According to a comment by a redhat engineer it seems that the problem (or something quite similar) has been addressed by Red Hat in their kernel-2.6.32-298.el6 . OpenVZ kernels (which I presume pve- kernels are based on) are still using the 279.9.1 build. How does one build...
Re: Similar problem
The redhat bugzilla entry (https://bugzilla.redhat.com/show_bug.cgi?id=815998) has status set to "CLOSED DUPLICATE of bug 827193" , so I thought that there is a solution after all. The problem is that the bug mentioned seems to be private. Not sure if it's only for RH...
Re: Similar problem
The system froze with the 2.6.32-15 kernel as well. Any more info I could provide? I could try to build the kernel with the patch from upstream (https://bugzilla.redhat.com/show_bug.cgi?id=815998), but I am unsure if there is a source package for the pve- kernel. Also the...
Re: Similar problem
Hi, I upgraded and booted a while ago. The new kernel also emmitted the oops:

Hardware name: PowerEdge R510
Driver unmaps unmatched page at PFN 0

Re: Similar problem
I also have been hit by this bug. Kernel emitted:
