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.

Do you have enough free space on the other disks of the Array to host the content of the emulated disk ?

 

Your diagnostics could help understand your situation better.

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.

I agree, those are also the two choices you have.

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

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.
