[pbs-devel] Problem with PBS and old CentOS 4.9 vm

[pbs-devel] Problem with PBS and old CentOS 4.9 vm

[Fabrizio Cuseo]

Hello.
I am testing from today PBS beta (last release, just updated) with PVE last release.

I have a problem with a 4.9 centOS vm. If i restore after backup, during the initial FSCK there are a lot of errors and filesystem problems.

I have tried to:
- change disk from virtio to IDE
- backup with vm off 
- make fsck, stop the vm, backup, and restore 

If i backup the vm powered off, when I restore it, no fsck is prompted at boot, but if I reset (without any activity) the vm, again the filesystem is full of errors.
If I reset the original VM, no problem during fsck at boot.

If i fix the restored vm, I backup it again (powered on or off), same problem. 

So seems the the problem is making and restoring backup.

No problem with a centOS 6.X (i am testing other OS versions).

Some idea ? 

Regards, Fabrizio

file system on centos 4.9 is buggy (old xfs version)?

Yes, I am making a lot of tests, and with a vanilla 4.9 centOS i don't have the problem.
But the strange is that with the old (full) pve backup, i have no problems.
I use ext3 filesystem (not xfs).
Now I am trying to rsync the old content to a new vm (rsync /) so the filesystem descriptors are new, but the content is the old one.

Thanks, Fabrizio

PS: i am using for test a vm with pbs, and for repository a MooseFS filesystem with 120Tbyte.

There is something strange..

Vanilla CentOS 4.9 (32 bit), backup, restore, fsck, no problem
I have copied (rsync) the content of my old centos 4.9 machine (but rsync, so the filesystem is new and clean) to the vanilla 4.9
Backup, restore, some problems with fsck
Backup (powered off), restore, power on, reset, power on, fsck, problems with fsck

Seems that during backup (and restore) something goes wrong with filesystem... 

The vm is on ceph with virtio drivers.

Regards, Fabrizio

Hi,
are there any problems when you backup to a non-PBS storage? Could 
https://bugzilla.proxmox.com/show_bug.cgi?id=2528 be related?

No problems with old backup procedure. But i don't use CT, is a VM.
