i guess moving data out of the array was not the right choice. I have to find a way. I want to drop unraid. In 2,5 years this is not the first time i'm in such trouble and it takes ages to recover. I never had such problems with my syno or my proxmox server.

i'm in trouble. I was transferring data out of emulated disk 4 when disk3 had errors and is now disabled. Disk 2 started also to have errors. Now in /mnt/user/ i can't see any files which were on disk3 or 4 But i can see /mnt/disk4 but not /mnt/disk3 godzilla-diagnostics-20210929-2226.zip

no i have not enough space on other disks. Right now my server is down i can't post diags. i have 2 parity disks (6Tb) I have 4 array disks (4,4,4,6 Tb). I have shares on disk 1&2 and others shares in disks 3&4. Disappeared disk is number 4. I really think disk 4 is dead as lsi controller doesn't detect it and it made some "click" noises on starting. If i can't move data from emulated disk 4 to new disks 5&6 (4Tb) i think i have 2 choices: - transfer data out of the array, add 2 disks, make a new config and transfer back data to the new disks. The downside is it will make a strong activity on parity drives. - buy a 6Tb disk to replace disk 4. but i prefer the other solution as i have 7 empty slots and 4 or 5 4Tb disks. Moreover there are no interessant deals on hdd right now.

Last week i started to have read and write errors on an array disk. I did not have time to deal with this as i had to move to a new house. Yesterday i started my server and now the disk is not seen anymore (even by the controller ). The problem is i only have smaller replacement drives. How can i deal with this ? Is it possible to add 2 drives to the array and transfer from the emulated disk to the 2 new ones? i guess not as parity will logically be rebuilt when adding drives.

finally got preclear running by uninstalling and reinstalling it. Guess it was a dependancy problem (perhaps due to interaction with nerd pack)

I can format the disks in exFat. i can't format them in xfs Preclear still stuck on starting. I found a forth disk from an ancient raid on synology. It's the same behaviour.

yes it's enabled. Usually i have no problems preclearing. But i haven't done this since a few months. Server has been rebooted 2 days ago for udpate of nvidia driver.

Hello, I'm selling my synology nas and i want to preclear disks to have spare. I threw 3x 3Tb western red in my sas expansion bay as unassigned drives. Unraid recognised them as linux raid member. Preclear won't run. It keeps showing "starting" I can erase partitions but i can't format them in xfs with the gui. What can i do ? godzilla-diagnostics-20210705-1207.zip

good news. Server is now running fine. Parity sync is now finished. I'll run preclear on the disks used to see if they really failing. Tank your @JorgeB for your help 😃

that's it. The sata connector was almost unplugged!!!

i have that multiple times in syslog. It keeps coming up. How can i know which controller/port is involved?

I certainly had it "moved" when reinstalling the cpu2 daughter card (the server is a Z620 with 2cpu).

thank you 😃 parity sync is started; but it's very slow: 20MB/S edit My bad docker service started and that was slowing down the process. now it runs at 150MB/S. Now i also have udma crc errors on cache pools (both vm and docker pool)🤥 The controller on the mainboard could also have a problem.

i have UDMA CRC error count at 15 on disk4 godzilla-diagnostics-20210308-1202.zip

i'm confused. I replaced sata cable, changed sata port and still I/O error. So i changed enclosure for disk 4; and still I/O error when doing check _n with gui. So in a terminal i ran xfs_repair -n on disk4 in the external enclosure and it's running but with gui i have i/o error. I have good hope for disk 4 as the internal enclosure in which disk4 was primarily had a problem. When i pulled disk 4 the latch of the enclosure was broken and the disk was not maintained as it should.

when i run xfs_repair -n on disk4 i have an input/output error.
