Volume lost on ReadyNas 104
Hello, I lost my volume on a ReadyNas 104. No errors have been logged according to the admin page, only a bunch of warnings around April this year. See output in attachment. I have not done a...

This should assemble, so I am puzzled by the earlier issue.
The event counters (13922, 13917, 13926, 13917) do show some lost writes - they should all be 13926.
Maybe try this variation:
mdadm --assemble --really-force /dev/md127 /dev/sda3 /dev/sdb3 /dev/sdc3 /dev/sdd3
Hi schumaku,
Thanks for your swift reply.
I do not understand - while having a few warnings - the volume gets lost. Also the NAS is currently reporting all disks are healthy (except there is no active volume).
Is there anyway to try force connect the volume again?
Cheers, Mark.

In February, the volume became degraded - meaning one disk dropped out of the array. The screenshot doesn't say which one.
Later on we see warnings that two additional disks were failing. Also that a third disk was removed.
All of these can (and often do) lead to data loss.
But we are only seeing the warnings in your screen shot, and there is lot of info that is likely missing. For instance, it is possible that the volume resynced after the February problem. Also we don't know what RAID mode you are using.

Probably the best path is RAID recovery software (ReclaiMe is one people have used here). You'd need a way to connect the disks to a Windows PC (usb adapter docks will work, some have multiple bays). And you'd need a place to offload the data.
It might be possible to forcibly assemble the array - not sure. I wouldn't put much stock in the disk health you are seeing now. Have you ever used the linux command line? Also is ssh already enabled on the NAS.
Hi StephenB,
Many thanks for your reply.
I've copied the status.log with the warnings hereunder. I have not removed any disks in the last years.
The NAS is in X-Raid mode. Also I 'suddenly' noticed that the volume seems to be there, but inactive. See attachment.
I am familiar with ssh and the command line. So any help as to try to reconnect the volume via a terminal is highly appreciated!
Kind regards,
Mark

[23/04/20 01:00:28 CEST] warning:volume:LOGMSG_HEALTH_VOLUME_WARN Volume MusicDrive is Dead.A little odd, since the volume name for X-RAID is always "data", and yours is "MusicDrive". So you must have started out in FlexRAID, and then switched before you did any expansion.

Is ssh enabled on the NAS? If it isn't then you'll need to boot into tech support mode and connect with telnet. We can give more detailed instructions if needed.
Given the dicey situation with the disks, I'd begin with running full non-destructive tests with smartctl, and then attempt to assemble/remount the volume. If successful, I strongly recommend that you back up the data before doing anything else.
Your problem may be power related -- not enough to spin the drives up properly. It could be the power brick or something internal to the NAS.
The best next step is to test the two "bad" drives in a PC with the drive vendor's tools. If they actually pass (except for the existing SMART errors), then that adds evidence that that is the issue.
BTW, you have your alert email set up wrong, which is why you didn't get any email warnings about this.
