[ovirt-users] Re: Guest don't start : Cannot access backing file
Hm... this sounds bad . If it was deleted by oVirt, it would ask you whether to remove the
disk or not and would wipe the VM configuration.
Most probably you got a data corruption there . Are you using TrueNAS ?

Hi,
i've a big problem, i juste shutdown (power off completely) a guest to make a cold
restart. And at startup the guest say : "Cannot access backing file
'/rhev/data-center/mnt/blockSD/69348aea-7f55-41be-ae4e-febd86c33855/images/8224b2b0-39ba-44ef-ae41-18fe726f26ca/ca141675-c6f5-4b03-98b0-0312254f91e8'"
When i look from shell on Hypervisor the device file is red blinking...
Trying to change SPM, look device into all hosts, copy disk etc... no way to get my disk
back online. It seems ovirt completely lost (delete?) the block device.
There is a way to manually dump (dd) the device in command line in order to import it
inside ovirt?
My environment
Storage : SAN (managed by ovirt)
Ovirt-engine 4.4.3.12-1.el8
Host centos 8.2
Vdsm 4.40.26
Thanks for help i'm stuck and it's really urgent
