ok thank you for following up my steps.

currently running 5% rescued and going on...

No, you'd need to do a new config and re-sync parity

after re-sync i can add rescued files from ud device ?

Not clear to me if you plan on using the new cloned disk as disk3, if yes you'd do a new config with it and re-sync parity, all data on there will be part of the array, if you plan to use another disk for disk3 than you'd need to replace and rebuild, then format (since it would still be unmountable) and then copy the data from the cloned disk to the array using UD.

i planned the second option but i was not aware of the first which seems more simple.

but i think i have to check files integrity on the cloned disk before syncing parity.

ddrescue went well and i recovered all files.

 

I did a new config with the new disk3.

Parity sync started but disk4 had been disabled.

So i guess i have to stop array to replace disk4.

I have no 6Tb disk spare.

i start thinking trouble is with the hotplug enclosure in which i have disk 2, 3 and 4.

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

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.

Post new diags.

i have UDMA CRC error count at 15 on disk4

Disk looks fine, but since both parity drives are invalid it can't be emulated, if you already replaced cables do another new config to enable all the disks and start a new parity sync.

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.

CRC errors don't reset but it they keep increasing there's still a problem.

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

edit : found: it's the port used for the m2-sata ssd of the vm-pool. I certainly had it "moved" when reinstalling the cpu2 daughter card (the server is a Z620 with 2cpu).

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

it's running ok now.

 

I feel like a black cat. 🙃

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 😃
