Front light blinking red and status Raid is degraded

[Glaven Clattuck]

Good morning everyone
I'm back on the forum after a long time for a new problem on my old 5BIG Network2, always hoping for your help.

For some days now, the NAS has had its front light flashing red, while all the LEDs on the HDs are blue.
The folders are reachable and the files are all ok.
But if I try to do some (Add or Move operation) everything is slowed down to death or it doesn't work at all. I can delete the files or even read them, but nothing else.
From the Dashboard in the RAID window, it tells me that the RAID is degraded and to change the HD in slot 1.

I bought a new HD and tried three times to do this but after so many hours (almost 24 hours yesterday) in the end there is always an error that blocks everything.
This time for example, it wrote that there was an error and all data is lost. Every time I have reinserted the original disk that the NAS says to replace, and again everything has returned as before, but obviously always with degraded RAID and with the operating difficulties that I mentioned above.
The NAS keeps suggesting me to change the HD because the data is not protected, but I don't know what to do anymore.
Your help is appreciated

p.s.To make you understand better, transferring a 5GB file from my Mac to the NAS, which normally takes a few minutes, now tells me it takes about 7 hours!!

Hi Glaven Clattuck,

Indeed you may have a fail disk.

If with the new one, the firmware failed to rebuild the raid that would mean you did not change the right disk. Can you explain how did you try to do it ?
And what is the slot1 for you ? first left disk when you see the slots side ?

Other point, I assume you still use the original disk, can you post these outputs :

Code: Select all

cat /proc/mdstat
mdadm --detail /dev/md0
mdadm --examine /dev/sd[abcde]8

and also

Code: Select all

dmesg

Hi Jocko
slot #1 is what the NAS tells me it is, i.e. the first one on the left.
In the Dasboard there is just an image that indicates which disk is faulty.
To replace it I followed the procedure indicated in the LaCie Dashboard.
From the RAID page, I am told which is the failed disk and to replace it. So with the NAS turned on, I change the disk and press the button indicated on the browser. There begins the synchronization phase, which since I have all 5TB HDs in RAID5 is quite long.
In any case this stops and to operate again I'm forced to put the original HD back in the indicated slot.

Other point, I assume you still use the original disk, can you post these outputs :

Code: Select all

cat /proc/mdstat
mdadm --detail /dev/md0
mdadm --examine /dev/sd[abcde]8

and also

Code: Select all

dmesg

These are the requested output:

If i understood well, the prob is on the md4, so i launch the same command that you request for the md0, to the md4.
This is the result:

clearly we have a problem here.
From here you can figure out which physical disk it is and on which slot?

I can redo the synchronization procedure, but maybe it's better to check the new HD first? Which is no longer new, given that it has started the synchronization procedure three times and something has been written about it. Maybe in the Partition Table?

wait for your tip

[Jocko]

Hi

I did not believe you still use lacie firmware.

So yes the data partitions are on partitions sdX2. According your last output the issue is on partition sda2. But now we have to know what is the physical disk with sda as kernel device name because (if I remember lacie sets weirdly kernel disk names.

So can you post

Code: Select all

lsscsi

if the command is not present you can lshw or hwinfo

Hi Jocko, thanks for your reply

I don't think I'm using the original LaCie firmware either, but I can't remember if, with your help, I updated it to your firmware.

However none of the three commands (lsscsi, lshw or hwinfo) are present...

[Glaven Clattuck]

Well, I did this extreme step:
With the Clonezilla software, i inserted the "failed" HD and the new one in two bay of my MacPro and clone the old on the new one.
After several hours, the procedure was successful.

So put the old HD in the NAS and the NAS remains with the front light in solid red, while it was blinking before.
Same thing with the new HD clone.
The led on the back of the NAS are all blue.

I can connect to the NAS via SSH or via Dashboard but this is the situation now.

Hi

According to your last output, we can confirm what disk is sda.

Code: Select all

[   44.760000] md: kicking non-fresh sda2 from array!
[   44.760000] md: unbind<sda2>

So sda is really the first left disk. It seems there is also some errors on sdc disk. So with two missing members, you can not reassemble a raid5
Do nothing on the original sda disk, maybe it is clean and you got previously a degraded raid5 by the faulty sdc in fact instead of sda...

First we try to assemble manually the raid with only 4 disks

Code: Select all

mdadm --assemble --readonly --force --verbose /dev/md4 missing /dev/sdc2 /dev/sdb2  /dev/sdd2 /dev/sde2

(keep this order sdc2 is member 2 in your raid according to a previous output) post the output and also if the raid is reassembled

Code: Select all

cat /proc/mdstat

Unfortunately this is the answer:

Code: Select all

[root@LaCie-5big ~]# mdadm --assemble --readonly --force --verbose /dev/md4 missing /dev/sdc2 /dev/sdb2  /dev/sdd2 /dev/sde2
mdadm:option --readonly not valid in assemble mode

Do you want me to try removing the --readonly parameter?

ok i did

Code: Select all

mdadm --assemble --force --verbose /dev/md4 missing /dev/sdc2 /dev/sdb2  /dev/sdd2 /dev/sde2           
mdadm: looking for devices for /dev/md4
mdadm: cannot open device missing: No such file or directory
mdadm: missing has no superblock - assembly aborted

Remove also the option missing (must be used only when you create a raid !)
