About restore of VMs

[Dmitry]

Hello, I had installed Proxmox 1.7 and after some time of work the system I saw that server was down.
I started the server and and I saw that system make some sectors remap opreation. After ~15 min was reset system and aftet it
I see JBD: IO error reading journal superblok with problem of mount PVE-root. So I can't login in TTY console.
In BIOS was set AHCI HDD mode. HDD is one SATA 1Tb WD blue disk.
I have success checked the surface of disk. I had some open-Vz VMs with needed data.
Could you reccomend anythink how restore datas from VMs?

Br, Dmitry.

Hi,
one way: put another big disk on the server and boot an live-cd like grml. In the live-system activate the lvm-vg pve and mount /dev/pve/data. If that work copy the content as fast as possible to your second big disk. After that you can try to mount /dev/pve/root (perhaps different superblock) to get the vm-configs.


Another way: copy the whole disk to another disk (also with live-cd and than dd-rescue or (not so good) with dd).
If your disk has trouble with the firsts cylinder, the first way is better - you read first the lv which is a little bit after the firsts cyls.

Good luck

PS: A right raid-level with an good raid-controller is very usefull. But I'm sure, you think also about this. Also an valid backup is an nice idea.

does the system boot now?

if not, it looks like you lost some data. hopefully you have a backup (vzdump?)

for the future: do not use use cheap desktop disk, instead go for 24/7 certified disks and use a hardware raid controller with BBU.

Hello, thank you very much for your advise. I realize free web project, therefore I'm using PC. Could you recommend some SOHO RAID controller for mirror SATA disks or HDD clone utility. I have tried to use Clonzilla, but speed of copy is very slow, about 280 mb per a minute. Br, Dmitry.
