March 10, 20206 yr Hello, I recently moved locations, and during my move, on of the cache drives that I have in a raid0 btrfs pool came disconnected... Array got started with only one of the 2 drives... After troubleshooting, I discovered the issue, and stopped the array, on the main screen the drive had become "unassigned"... When I re-add the drive, UnRaid now warns me that the pool will be formatted when the array is started (I think it is trying to boot back in normal mirror raid mode, and then will make me switch it back to a raid0 array) Is there a way to just re-add the drive in the original raid0? or am I forced to format the drives? qw-diagnostics-20200310-0910.zip Edited March 10, 20206 yr by Warrentheo

That is the correct, the question is is it possible to skip the conversion to the normal raid1 mode, and leave it in the raid0 mode...

It is a 2Tb pool, 80% full, and was originally in raid0, the only issue it had is being booted once with one drive missing... I am trying to see if it is possible to start it again in raid0, or is the array already corrupted?

March 10, 20206 yr Community Expert Since the pool was already converted it's not possible to maintain the old profile, that would only be possible if you hadn't started the array with a missing device.
