Deleting iSCSI LUN did not free my disk space

How much data is on your NAS?

Perhaps backup your data, do a factory default (wipes all data, settings, everything) and restore your data from backup.

Thank you for your feedback mdgm.

I have about 2,5 TB on my NAS. I might be able to find somewhere to temporary store my files to do a system restore, if not i have to buy a spare disk. But only if nothing else works.
I would realy like to find out why it's happening and why, and maybe find a solution.

I plan to use the iSCSI LUN, and i need to be able to create and delete without this beeing a problem.

Did you find a solution regarding the other two posts with the same issue? I guess this is not normaly a problem on this NAS?

can you send me your logs (see the link in my sig)?

They are sent:)

I deleted the last iSCSI share on the NAS now aswell, so no iSCSI LUN's are existing on my NAS.
Still same problem.

When did you start observing this problem? Since the upgrade to 6.1.9 or before?

On an unrelated matter, I see you are using WD Green disks. It appears the Load Cycle Count is rising rapidly on these disks.

I see you last did a factory default on 6.0.0.

I have only created iSCSI shares on 6.1.9, so I dont know if the problem was there on earlier versions.
I got hold of some spare disk's now so i can preform a factory reset after i have copied everything.

After i have done that i will try to create a iSCSI LUN and see if the problem is still there.

About the load cycle count. I can see et is very high. I found this article regardig WD disk's http://www.timoroso.com/journal/9
Are you familliar with a way to use “wdidle3” on the RN104?

Would suggest running that before the factory, but after backing up your data.

I have now preformed the factory reset (and fixed the LCC issue).

After the factory reset i created a 10 GB iSCSI LUN and deleted it again. I still have the same problem. The 10 GB is still showed as used space on my NAS aafter I deleted it.

I found a workaround. If i connect WinSCP to the NAS and go to "Volume name"/.purge i can find my 10 GB share there, i can manually delete the files and the space is freed.
Will this action have any other consecenses on the NAS?

Now i worry if my disks arte going to break down. I can see the are only good for 300 000 LCC, and my disks passed that already. The idle3-tools stoped the rappid LCC increase.

Make sure you backup your important data regularly.

Yes :)
And thank you for your help.
