Disk 4 in my Unraid setup has a red cross and is disabled. According to the information in the Unraid dashboard, the disk is healthy although there were a lot of errors during parity rebuild.

Before doing anything I prefer to have input of the specialists in here  

 

In attachment the diagnostics report.

 

Optional question: My system is still in reiserfs. What are the steps to change it?

Disk4 dropped offline, could be a controller problem, SASLP is not recommended for a long time, but since there's no SMART report power cycle the server (just rebooting might not do it) and post new diags.

I've shutdown the server and started it again. My guess is there are some problems with the sata cables and or sata connections on the motherboard as after starting the server another disk was also missing. Now I'm back with only disk 4 having a red cross. Unraid tells me now that disk 4 is unmountable. Do I run xfs_repair without -n first now?

Emulated disk4 didn't mount because disk3 dropped offline:

 

Aug 25 01:41:22 ToscheStation kernel: ata10.00: failed to IDENTIFY (INIT_DEV_PARAMS failed, err_mask=0x80)
Aug 25 01:41:22 ToscheStation kernel: ata10.00: revalidation failed (errno=-5)
Aug 25 01:41:22 ToscheStation kernel: ata10.00: disabled

 

Check/replace cables, might also be a power related problem.

After having checked the cables, the problem was still there and on top of all there was a power cut in our street. After that I rebooted the server but the problem with disk 4 being disabled was still there and on top of it disk 3 was missing.

As I've had problems in the past with SATA cables and SASLP controllers aren't recommended, I've replaced the motherboard, all sata cables and the controller card (I'm using an LSI 9207-8i now). The only thing that wasn't replaced is the PSU.

Right now I have disk 1 and 3 missing and disk 4 unassigned (disk 4 isn't even being detected as a device). What should I do now? I've read a lot about Tools -> New Config -> Retain current configuration: All -> Apply but I'm not sure if this is the way to go...

I also got the message stale configuration. Should I run a file check of the USB stick first?

I've also tried to run the diagnostics tool but this has been running for more than 30 minutes now without any luck to download the diagnostics. Is this caused by the stale configuration?

With so many missing disk there's not much you can do, are the disks being detected by the HBA BIOS? Assuming there's one, if not connect them to the onboard SATA and see if they are detect by the board BIOS.

 

Also see if you can get the syslog at least:

 

cp /var/log/syslog /boot/syslog.txt

 

then attache here.

Attached the syslog. Disk 1, 3 and 4 are connected to the LSI controller card (it's brand new as well as the SAS>SATA cable)

Just now seeing this thread since it was weeks old before it was revived. Just a few comments that haven't been made.

These 2 do not belong together.

Get an UPS

HBA has a BOS installed, so check if the disks are detected there, if not they also won't be detected by Unraid, swap cables with another one to see if it's really a disk problem, note that some disks won't power up if there's 3.3v SATA connected, in doubt use a Molex to SATA adapter to test.

1st try: New SAS > SATA cable -> detected only 1 disk (my parity disk)

2nd try: Old SAS > SATA cable + two 1 MOLEX > 2 SATA power cables -> detected 3 disks (parity disk, disk 1 and disk 3)

After the 2nd try, I rebooted the server to see what Unraid would tell me. Parity disk can be seen as well as disk 3. Disk 1 is missing according to Unraid. Disk 4 is unassigned (which is logic as the controller card couldn't detect it as well).

So what should I do next?

detected 3 disks (parity disk, disk 1 and disk 3)

 

Disk1 is still missing, you need it since there's already a disabled disk.

The controller card sees the parity disk, disk 1 and disk 3 but not the disabled disk.
Unraid sees only the parity disk and disk 3 and tells me that disk 1 is missing. For the disabled disk it says unassigned.

What's the reason why the controller card sees 3 disks and Unraid only 2?

Connect disk1 to the onboard SATA port6 which is currently unused.

Did that. All disks, except for disk 4 that is still unassigned/undetected, are available.

If the disabled disk is now the only one missing you should be able to start the array without it. Do that and post new diagnostics

There are what look like power/connection problems on disk1 and another disk not being detected, maybe the disabled disk? Replace cables on those and post new diags.

After replacing cables, post a screenshot of Main - Array Devices with the array started along with those new diagnostics

 

Disk1 isn't missing but it is unmountable. Emulated / missing disk4 is mounted but empty. All other disks are very full (not recommended).

 

Is it expected that disk4 is empty? Did you format it?

Ok so after replacing a lot of cables I can see all my disks again, even the disabled one. I haven't started the array as Unraid tells me that the disabled disk is a new device. 

Do I continue by starting the array and putting the diagnostics here? Or should I do something else?

That means it is going to begin rebuild when you start the array. Let's wait on that.

 

Set disk4 to not assigned, start the array, then post new diagnostics. And a screenshot of Main - Array Devices, be sure to include the full width
