Parity Swap & Drive Replacement Failure...

[hshutt]

Pretty sure I messed up big time..

Attempted to upgrade my 12 TB parity to 18TB to give me more max space in the long run. Also bought another 12TB to add to my array.

Before I touched anything I had a 12TB parity and a 8TB & 1TB in my array.
Read the parity swap procedure but followed the steps for replacement disk mistakenly...... Basically I removed my parity drive and started up, tried to assign the 18TB drive and parity starting building. After it was done (the whole time showing it was building on my 18TB) it came up and my 12TB was still my parity drive and my 18TB was unassigned. I then performed the parity swap correctly and the copy worked, unsure if I lost anything on the parity due to the issues.

Afterwards I, for some reason, decided I was going to remove my 1TB and put in the 12TB in it's place (this 12TB is the new one and not the old parity drive). Did it's file system expansion/disk rebuild after formatting drive. All of these things took 14+ hours. After this last step the array came up, new drive still showed empty. Stopped and started array, and now disk 1 (new 12TB) shows unmountable: unsupported or no file system. Unsure if I can do anything with it, tried to check disk in maintenance mode but need to do some research on how to use it. Can't start docker as my docker.img lives on disk 1 from what settings >docker says.

Previous order was 1TB was disk1, 8TB was disk 2 and 12TB was parity.

Data is still on disk 2 8TB. Nothing on the new 12 TB and my 1TB shows it will overwrite the data if I add it to my array. I downloaded unassigned drives and mounted the 1TB, I see the files still in there. I checked the 12TB old parity via unassigned drives and only shows two drive folders, one is empty and the other has the data from the 1TB. Does this sound like there's no chance in hell to get my data back or is this still somehow possible?

New order is 12TB disk 1, 8TB disk 2 and my 18TB parity. 1TB unassigned and old 12TB parity unassigned.

Would I be able to move the 1TB data from there to my new 12TB, add the 1TB after format and rebuild parity? Maybe restoring data to the 1TB or something similar?

I know I done screwed up, I wouldn't be posting this if I didn't have an entire library of files for work and a well established plex library. Thanks for any help, and I know I'm an idiot...

You can copy the data from the old 1TB to the array using UD.

Alright, if I copy the 1TB to my 12TB in my array the filesystem name doesn't need to be modified does it? Shows a different name for the folder in "/mnt/disks". Just use cmd line to copy all files from my UD mounted drive to my new one in the array, nothing to be forewarned about? Thanks for the help JorgeB, I see you all over these forums dealing out your wealth of knowledge.

 

Also with the array started disk 1 (my new 12TB) is showing unmountable for no/bad filesystem. Doesn't show mnt/disk1 in terminal, only disk2. I'm assuming I should just format again and try moving the files?

Well I ran xfs_repair a couple times in the gui for disk1, could now access the drive and had a lost+found folder with an insane amount of folders, some don't hold any info. Moving all the files over from my old drive "mv * /mnt/disk1" hopefully it works.

Correct

Man I love Unraid... Thank the heavens! All I had to do was exactly that, got the drive back up with xfs_repair and moved my files over. Everything seems to be working great, thanks for the help JorgeB! ❤️

 

I was very cautious to make any further steps after all that had happened.
