March 26, 20233 yr Ok, I had a drive failure on my unraid setup. A 3TB drive failed, leaving only the 4TB parity drive. Since I wanted to upgrade anyway (I like unraid) I decided to add an 8TB SSD for my parity drive. That is now done syncing. I now have two parity drives: the old 4TB spindle and the 8TB SSD. I now want to add an 8TB spindle drive as a disk. But it will not let me, stating the parity drive must be biggest. So I tried removing the 4TB parity drive: that gives me a "to many disks missing or failing" error. When I try adding the 4TB parity drive as a normal drive it gave me the same error. See the screenshot for my current config. Is there any way to restore my information, use the 8TB SSD for parity and the other drives as normal disks?

Exactly how did you do this? The steps should have been: Stop the array Set the parity1 slot to Unassigned Start the array to commit that assignment change After that you can if you want then add the old parity drive as a new data drive following the standard procedure for adding a drive as documented in the online documentation. You cannot do both changes these in one step.
March 26, 20233 yr Author This worked. I tried it a couple of times before, but it kept saying missing to many disks. This time it worked exactly as you said!
March 26, 20233 yr Community Expert I am guessing, but I suspect that you tried to unassigned the parity drive and make some other change without starting the array to commit the removal of the parity drive. Easy to do
April 19, 20242 yr hey i have a problem with my disks. i would upgrade but my unraid bug it says Too many wrong/or missing disks
April 19, 20242 yr Community Expert You seem to have the same drive assigned to disk1 and parity2. Not quite sure how you got yourself into that position. Have you tried setting parity2 to not assigned and then starting the array.
April 19, 20242 yr Community Expert You cannot have a new parity a a new disk at the same time, what was the original array state? If there's no data to recover do a new config
