Title:
Failure after Ubuntu upgrade - libvirt volumegroup no longer has an
lvm2 signature
Status in Ubuntu on IBM z Systems:
Triaged
Status in multipath-tools package in Ubuntu:
New
Bug description:
After Ubuntu upgrade following problem occur.
One of the volumes in the libvirt volumegroup no longer has an lvm2
signature for some reason. Someone must have overwrote it.
However libvirt has been removed from /etc/fstab already, to prevent
any issues in booting.
Somehow this causes so much trouble with the multipather that even the
boot lun is not named as it was previously. (Persistence in naming is
lost)
/ gets mounted, but /boot fails to mount because of the change in naming, and
this is what is causing the rescue prompt.
I can successfully mount /boot by UUID instead.
While a corrupted volume is a corrupted volume, I would have expected
the multipather to handle it more gracefully and not impacted other
LUNs in this way.
