Read Only Filesystem After Backup

[richard316]

Hi,

Im new to proxmox, and using Proxmox 3.2-1.

My KVM Ubuntu 12.04 is using sata as hard disk and qcow2 for its format.

After Backup using Vzdump Snapshot mode, the filesystem of the KVM becomes readonly.

I need to restart the VM then, fix disk errors for the VM to be up and running again.

Image size is around 35GB.

Could you point me to the right direction why the filesystem of my VM becomes read-only?

Any Help will be much appreciated.

Please see details below.

could be a faulty hardware. check ram and physical disks. I assume you run server hardware with ECC ram and hardware raid?

and upgrade your host to latest version, see:
