vps file lost after server crash

[Jingyun He]

Hello, All,
Today one of our servers was crashed, after I rebooted the server, one
vps can not boot up, and it needs fsck, after I run fsck command, a
lot of files lost, and also some file content was changed. Not sure
how could it happen, do you have any advice that can avoid this or
recover the data?

Thanks.

Are you DomU's HVM or PV?

What backend are you using? Maybe post your config, or at least the disk
configs.

And what filesystem in the DomU?
