      Well at least for now, the I/O errors have stopped after I replaced the bad disk in the host array and reverted the VM.

      I'll keep an eye on it and report back if the issue comes back.

            On the guest OS there is only 1 disk (it's presented from the array).

            I checked the smart stats on each drive and found no issues. MD was also fine.

                  Although on a separate note..... this is a shit desktop... that is acting as the hypervisor... so errors really shouldn't surprise me.

                    All disks in the host are marked as "Old_age" so there really isn't much that I can do besides assemble something else.

                    Hopefully out of newer equipment.

                      Maybe I'm reading this wrong.. Smart overall-health self-assessment is passed on all drives.

                      So maybe it's just a column saying "it'll fail here"

                        I'm performing long tests on each of the drives to confirm the information I have is accurate. I'll update in ~90 minutes.

                                I'm curious as to why the VM is showing these issues, but the hypervisor isn't listing any issues at all.

                                  My guess is a driver issue. You are not getting errors from a disk but from an abstraction of the array. So you are two interfaces separated from the actual disks.

                                    I'll just dump the VM, at this point it's been 4 days without a clean backup. It's only a Ubuntu VM with an NFS/SMB share.

                                      So after building a new NFS/SMB vm (and deleting the old one) the new system seems fine.

                                      Something must've got corrupted because of the smartctl errors.
