Recover vm after lvresize

[Filippo Merli]

Hi,

after shrink a standalone vm volume with lvresize is not possible anymore access the volume data.

The vm start but is not possible to open a terminal. Is there a way to access the data from another vm or from dom0?

Filippo Merli:

Enabling debug mode in Qube Settings might get you a terminal so you can
see what's wrong. Also can try sudo xl console [vmname] in dom0 when
it's powered on. It is possible to copy the volume to a file to attempt
recovery in another VM.

Thanks, with sudo `xl console [vmname]`  I have been able to open a terminal in the damaged vm and solve the problem. The problem was that the block count of `xvdb`, the shrinked volume mounted in /rw , exceeded the size of the device. So I just set the device size with `lvresize` to a bigger one and everything seems to work.
