disk issue

[tincboy]

I've a vm which can't boot up,
I've used Centos-LiveCD to recover the data from it, but while I'm going to for example /mnt/lvm/srvubu-root/home/myuser I got Input/output error
Is there any way to fix bad blocks on that raw file and restore the data?

any help will be much appreciated.

Hi,
i have one server, where it's nessesary to use ",cache=writethrough" as parameter for the disk in the config-file. Without no booting possible (io-error) with the parameter all runs fine.
Perhaps it's help in your case also.
If you copy the rawfile from the pve-host to /dev/null do you get also io-errors? Than is something wrong with your disk - see also messages/syslog.
