iSCSI LUNs deleted but space not freed up
Firmware: 6.6.0 Attached as a replication target for backup storage (UniTrends). I show LUNs totalling 27TB out of a usable 36TB (48 raw). However, free space is reported as 1.91 TB and I'm receiving performance warnings for having less than 5% free. I should have close to 9 TB available - where is it? I think the scenario that created the current predicament is as follows: 1. Deleted old LUNs 2. As they were deleting in the background, I created the new LUNs (since deletion takes a long time and the free space number was at least increasing at the time. 3. Once the new LUNs were created, I didn't think too much about it until I added an SMB share for some SQL backups and quickly ran out of space even though they consumed no more than 2TB. 4. I moved that SQL share to another server entirely and delted it from the ReadyNAS - gained back the 2 TB. I've seen at least 2 or 3 threads that are very similar to my situation and they all end with, Send me a 'PM'. Any chance someone could let me in on the secret - would love to be able to continue using this device and all of its storage. :)
