[SOLVED] Backup VMs from filesystem

[SunBlack]

Hi all,

we have currently some hardware issues with out server (1 defect HDD and 1 HDD which only works for a limited time in a RAID5 :-/). Because of this the filesystem got some issues. Now I can login into the system via ssh, but the Web-GUI doesn't responds anymore. As I can still access the system via ssh: Which files I have to save to can restore the VMs later? (vzdump is not a real solution as the 1 HDD only works for a limited time, so I don't want have much write access on it).

Regards
SunBlack

That highly depends on the storage type.

Configs are located at /etc/pve/qemu-server.

If you have them on a directory storage, you will have raw or qcow files. If you run LVM or ZFS you will have to DD block devices to another machine / disk.

For ZFS: ZVOLs are located in /dev/zvol/<pool>/<optional dataset>/vm-<vmid>-disk-<disk #>
For LVM: /dev/mapper/pve--vm--<vmid>--disk--<disk #>

Remember that the latter two are block devices like for example /dev/sda so you will need to handle them like physical disks and use DD to copy that data to a disk or file.

Well thank you. Before I could store remaining VMs with DD the RAID destroyed itself completely be losing partition data. Nevertheless thank you
