RAID 10 clean, degraded

Geaves, if you'll allow me to interrupt ...
That disk seems to be fine (although a little hot, 40º). I would do the same with the others and compare the number of starts and / or the number of hours of operation. Assuming they were purchased at the same time, if this disk is significantly lower it could be the result of a hardware failure preventing this disk from booting.

The others... (2/3)

The disc in question has 11,303 hours of use and the other three have 15,197, 15198 and 15,198

Did you create the Raid10 with new discs?

Never, but last year somothing appened, I don't know if it is relevant, you can see here OMV Raid Missing after reboot

It is also possible that I have been using 3 disks instead of 4 for about 5 months ... or not? Isn't there a way to get notified if one of the 4 disks in RAID10 goes missing or has problems? I only noticed it by chance by checking some configurations. The S.M.A.R.T.test is performed every morning at 6:00 am. on every disk but never got any alerts. Thank you.

I'm sorry, my correct answer is: "yes, in origin I create the Raid10 with 4 new discs". Thank you.

Thank you. Let's see what geaves thinks of this ...

Initially the drives appear to be fine, either mdadm 'threw' the drive due to some intermittent fault, the drive certainly did not remove itself, otherwise the raid would have become inactive.

I'm leaning toward an intermittent fault, which leaves either the sata cable and/or the sata port the drive is connected to

I agree. Replacing the cable is definitely worth doing to start. But before the shutdown to take care of the hardware inside the case I think it is necessary to fix the array, or can we fix it later?

You can fix it later

Zoki · Dec 20th 2021

Bit before touching the hardware of an already degraded RAID you should take the time to do a backup (yes, it takes a long given the amount of storage).

zerozenit · Dec 20th 2021

I changed the cable, after reboot "Failed to start File System Check on /dev/disk/by-label/REDRAID4X12.

What is the best option to continue? Thank you.

Wasn't expecting that, that would suggest there is a problem with that array, or at least it's file system, the norm to do this is to run it manually, but that is on a clean array, I have no idea what affect this might have on a degraded array, particularly a Raid10.

So, login as root and run fsck /dev/md0 and accept everything with a y (yes) or fsck -y /dev/md0 this means it will correct errors without user input. I have no idea how long this take given the size of the drives.

So, login as root and run fsck /dev/md0 and accept everything with a y (yes) or fsck -y /dev/md0 this means it will correct errors without user input. I have no idea how long this take given the size of the drives.

Thank you geaves it's ok, fixed, the system is up and everything seems working fine. Obviously there is always the problem of the fourth disk not present in the array.

These are the check commands:

In Raid Management I have sda, sdb and sde, not sdf. In Recovery -> Devices there is listed only the mysterious sdd...

What to do? Thank you so much for your support.

Although the system seems to work correctly, I have read the logs and there was a problem at boot "quotaon: cannot find /srv/dev-disk-by-label-REDRAID4X12/aquota.user on /dev/md0 [/srv/dev-disk-by-label-REDRAID4X12]" and therefore "Failed to start Enable File System Quotas". Can this help us?

The recovery will not work in this case as blkid has identified /dev/sdf with a raid signature, to use recovery you would have to wipe the drive first, a long process given the drive size. However, mdadm --add /dev/md0 /dev/sdf should add the drive back to the array

Yes, but, I've never had to deal with this personally and AFAIK this was disabled, but it may not be OMV4, I'll tag a couple of the other mods who know more about this than I do, crashtest macom

There may be a number of errors, found in the logs, that are harmless. If this is not affecting you in any tangible way, other than the log entries, I wouldn't worry about it.

Otherwise, you could give the following a try.
___________________________________________________________

Turn the quota service off.

sudo /etc/init.d/quota stop

(In the following examples, substitute the appropriate labels for your drives.)

sudo quotaoff --user --group /srv/dev-disk-by-label-DATA

sudo quotaoff --user --group /srv/dev-disk-by-label-RSYNC

I made a backup (very long) and then wiped the 4th disk. At that point I did the recovery of the raid. Everything went smoothly, thanks.

I then upgraded from OMV 4 to OMV 5 with simultaneous upgrade from Debian 9 to Debian 10 following these dleidert instructions. It all worked out for the best.

I really appreciate the help from the forum. Thank you all.
