tried to expand with xraid off....NAS now thinks there's a raid 50 or 60 volume present
Hello, Was helping a friend out with a 428. wanted to do volume expansion but without xraid as my experience was that adding two additional drives, xraid made the volume go from raid 5 to rai...
If the NAS has verically expanded volumes, even if that expansion was done by XRAID, it cannot change back to XRAID once switched to FlexRAID. I do not believe that was always the case, nor do I understand why it now is; but it is.
It sounds like you have come across a bug in the OS. But first check either mdstat.log in the downloaded llogs or issue a cat /proc/mdstat in SSH to be sure there really are no RAID50 or 60 volumes.
You could try the CLI volume_util via SSH and see if that works. But I'm sure the GUI calls it, so you may run into the same problem. Use volume_util -help for usage instructions.
If you do have vertically expanded volumes (which mdstat will also show), I don't really recommend you try to use BTRFS directly to expand. I've not experimented with it enough to know the pitfalls, if any. If something other than vertically expanded volumes is keeping it from switching to XRAID, I have done that. But it's not for the novice.
