Hi All, I have a VM with ephemeral root on RBD spewing I/O erros on boot after hypervisor crash. I've (unfortunately) seen a lot of hypervisors go down badly with lots of VMs on them and this is a new one on me.
I can 'rbd export' the volume and I get a clean filesystem. version details OpenStack: Mitaka Host OS: Ubuntu 16.04 Ceph: Luminous (12.2.4) after booting to initrd VM shows: end_request: I/O error, dev vda, sector <lots of sectors> Tried hard reboot, tried rescue (in which case vdb shows same issue) tried migrating to different hypervisor and all have consistent failure. I do have writeback caching enable on the crashed hypervisor so I can imaging filesystem corruption, but not this type of I/O error. Also if the rbd volume doesn't seem to be dammaged since I could dump it to an iamge and see correct partioning and filesystems. Anyone seen this before? I have the bits since the export worked but concerned about possibility of recurrence.
