Hi all. I would appreciate your help. 2 of my drives are disabled (Disk 1, and Disk 7), and I've 2 parity drives. Disk 1 was disabled for sometime, and the data was emulated. But when disk 7 got disabled, the content of disk 7 where disappeared, although the status is (Disabled, content emulated). When I tried to browse disk 7, I got "Invalid path" or something close to that. Online search indicated that it might be a file system corruption. Disk 1: I've unassigned the drive and tried to assign a larger drive (18TB), then discovered that it's not possible, as my parity is 8TB. The current status is "unassigned". Since unassigned and disconnect disk 1, I have only started the array in "Maintenance mode" once only. I didn't start it in normal mode. Disk 7: After starting the array in "Maintenance mode", I tried to "Check Filesystem Status" with -r and without -r. The repair button didn't appear. Didn't do anything else. The current status of the array is stopped. Question: What is the best way to proceed with minimal data loss? I'm moving my data to the new Unraid server, and will do a new config for this server. So rebuilding the drives in not really important unless necessary. I've attached the logs before and after unassigned disk 1.

Does Disk 2 has any signs of failing that required replacement? Or rebuilding the same disk is enough? Thanks.

Thanks JorgeB. The extended SMART test had read failure. It didn't pass the 30% (Attached) tower-smart-20260516-1735.zip

Hi all, I'm getting read error in "Disk 1" and "Disk 2" got disabled. While copying some data from the array, the server suddenly shutdown (2 times) I would appreciate your suggestion wither I should rebuild the same disabled disk again (Disk 2), or replace it with a new drive. The replacement will be a 18TB as I don't have a spare 8TB. The first diagnostics is directly after booting up the server after the unclean shutdown (20260514), and the second one is recent (20260516). Thank you in advance. tower-diagnostics-20260514-1759.zip tower-diagnostics-20260516-1056.zip

It worked. Thanks JorgeB

Tried the safe mode. Same issue

Hi all, Today my USB drive has failed, I've downloaded the latest backup from Unraid connect and installed it in a new USB drive (Using Unraid USB Creator). When booting the new USB, I can see Unraid IP address in the screen, also I'm able to ping this IP address from my PC. However, unraid web ui is not working. Tried to run with GUI mode, the "localhost" page is also not responding. I would appreciate your help. The diagnostics is attached. Thank you. tower-diagnostics-20241118-0945.zip

I'm not familiar with sonarr and radarr, but this should work: - Edit the docker - "Add another Path, Port, Variable, Label or Device" - The SMB share will be under this path "/mnt/remotes/<SMB Share Name>/" Then the docker will have access to the SMB share similar to the array

Are your apps installed as dockers in UnRaid? Add the paths of the SMB shares and UD moints to the dockers, then add them as a new source.

Not sure if Symlink / soft links will work, but why you don't just map multiple drives in your main PC? You can add different sources to your Plex (Array, SMB shares, unassigned drives, etc.)

Have you tried plugins like "File Activity" or "Open Files" to see what files/processes are currently being active?

As far as I know, SMB and NFS shares cannot be added to the array, as they are not viewed as a "Drive" to other unRaid server.

You're right, this was the issue. Reduced it to 100GB and everything works fine now. Thanks a lot @trurl and @JorgeB

The one I've tried is "Media"

Hi all, When switching the Share "Primary storage" from "Cache" to "Array", dockers like rtorrent and FileZilla can't write new files, even in SMB shares. Switching back to "Cache" then everything works fine. I've seen the below thread, but I don't understand why the using (/mnt/user/) path doesn't work with the "Array"? I remember it was working fine in older updates. Appreciate your help. Thanks. tower-diagnostics-20240227-1735.zip

I've restored the backup in a new USB stick. Every thing looks stable now. Thank you @trurl

Yes I do. Should I do full data restore? Or just for the corrupted files? Thanks

Thank you! The array is back online again, however, there are some issues. - Some dockers and plugins got corrupted. The Community App tab disappeared. - Loading the docker icons in the dashboard page is very slow. The server is overall slower than before. - Many disks have UDMA CRC error. Although recently, I've changed the power and Sata cables - Every time I restart the server, the Cache drive goes to unassigned. Appreciate your suggestion tower-diagnostics-20230217-1030.zip

Attached. Disk 6 is rebuilding now. tower-diagnostics-20230209-0746.zip

Disk 6 the drive that got disabled Cache (nvme0n1) the cache ssd that is shown as unassigned Is there any risk of losing the pool data (cache)? It has all the dockers, I've a backup for it.

Hi all, Few days ago, one of my drives had read errors and got disabled (Disk 6). I stopped the array, remove the disk from the array, started the array again, saw the disk in unassigned but I wasn't able to select it in the array (No disk). So I shutdown the server, changed the disabled disk cables, started the server again, then the surprise. The cache (NVME) was shown under the unassigned devices, when I add it to the pool, it says it's a new device. Also there were many disks with UDMA CRC errors. I've attached the diags before the first restart and after the restart. Appreciate your help. Thank you. tower-diagnostics-20230209-0626 (After Restart).zip tower-diagnostics-20230206-2321 (Before Restart).zip

Thanks. True, I misunderstood the when I saw the options under "Preserve current assignments". I thought if I select "all", the emulated data + disk data will both be restored to my drives. Anyways, I've done what @JorgeB mentioned and everything worked as expected, the parity sync is in progress. Thank you all @JorgeB, @trurl, @itimpi. I will mark this issue as resolved. Lessons learned: - Avoid SATA power splitters - Avoid motherboard SATA ports and get SAS HBA

So in the New Config I've to select "Array Slot", correct? If I selected "All" and I don't have enough space in the drives, what will happen? Anything else I should consider before applying? Thank you.

How can I choose between rebuilding the disks or parity? Rebuilding the parity is more suitable for me.

Almost done copying my files. As for assigning the 2 disks back to the array again and start rebuilding, should I add both disks together? or one by one (Finish rebuilding one then add the second)? Thanks
