Dell MD3220 reclaim used capacity
I was wondering how to reclaim used capacity after the deletion of files from a disk pool.
There is currently only ~5TB of files on the disk pool but MDSM is reporting 10.437TB used capacity.
No Events found!

Hello StGeorgeA.
So, unfortunately the SCSI unmap commands aren't supported on the MD arrays. So, either leave it as is, and keep a close eye on the space available, or backup the data, delete the virtual disk, and recreate it smaller, then restore from the backup.
I wish I had better news for you, but in this instance, I don't.
