Hello,
I know this is probably something recurring, but I searched for a way to troubleshoot it and can't really find something like my case.
I have a thick provisioned volume of 25TB, containing some thick provisioned LUNs, no dedup nor snapshots (neither at LUN nor volume level).
The sum of the space covered by LUNs is about 12TB, but the volume shows less than 600GB available.
I tried some commands and it seems that the remaining space is "reserved" but not available...and I can't understand why.
Can you please help me troubleshooting this situation? How can I recover the missing 12TB?
Thank you in advance!
Little prologue: on the same aggregate there was a volume where dedup was ON and its temporary files probably grew over the total amount of space of the aggregate. This locked two thin provisioned LUNs within the 25TB volume. So I resized these LUNs, and made them thick.
Some command outputs:
