Hello List,
I have a volume that appears to be full despite having multiple
Terabytes of free space available. Just yesterday I ran a re-balance
but it didn't change anything. I've just added two more disks to the
array and am currently in the process of another re-balance but the
available space has not increased.
Currently I can still write to the volume (I haven't tried any large
writes) so I'm not sure if this is just a reporting issue or if writes
will eventually fail.
Any help is appreciated. Here's the details:
