      MD RAID 10 is configured on this box for the storage space. So I can check that as well.

        Should be the very first thing to check.

            That is common in scenarios where you have filesystem corruption.

                  it looks like xvda is having issues according the current screen.

                  Might have to replace that drive...

                    At the moment the system appears to just be progressing through the blk_update_request with I/O errors for individual sectors on XVDA.

                    Should I abort this operation and find a replacement drive? Is it worth it to let this continue?

                      Hard to say. Real data on it? Would try to get a last backup first before doing filesystem operations.

                        Yeah, all comes down to the value of recovery, really.

                          I don't mind tearing down the system, it's only running 1 VM that I'm backing up my VM's too. Which those delta's get pushed off nightly to another disk.

                              And the system is in recovery mode. ..

                                Manual fsck is no fun.

                                  At least all of the instructions are there, and this is a learning experience.

                                      All disks in the array appear to be fine according to MD.... So this is clearly this is something with the VM.

                                        So I was able to just restore this VM to a snapshot from the other day.

                                        Should I perform another fsck on this virtual system?

                                          Not if it does not prompt you to.

                                            So how can I check to see if whatever caused this issue is still present? I mean if it just happens from time to time, fine.

                                            But wouldn't it be good to know what caused it?
