Backup corrupt my Linux VM

[Testani]

Hi team,
i'm facing a very big big problem. On my cluster VZDUMP of my linux VM results in a corruption of disk, fs become RO and a reboot break down the VM boot. How can i avoid this?
Anyone with same problem?

do you use by any chance 'sata' as you disk controller for your vms? if yes see here: https://bugzilla.proxmox.com/show_bug.cgi?id=2874

ouch, have i to migrate all my disk away from sata to scsi/virtio?

 

[dcsapak]

it seems the users in the bug could not trigger that with scsi/virtio disks (we couldn't here even with sata disks...)

If I may ask.. why did you pick sata in the beginning?

these VM are coming from ESX infrastructure. How can swap bus to scsi/virtio easily?

depends on the guest os and how it's configured. for linux it should be enough to reconfigure the vm, and adapt the boot/mount entries (fstab,systemd-mount, etc.) for windows i have no idea sorry
