Not returning free space

[Knowltey]

All of the sudden my NAS has started a behaviour of not returning the free space to be available after deleting contents from the pool. (Deleted it from the recycle bin and everything as well)

Here is an example of what I'm seeing in the reporting: http://i.imgur.com/PYFa2GH.png

All I did there was delete the files on that particular dataset nd it removes the files, but also deducts their size from the available space as well while doing so. It was set up as a 1TB pool, but due to this issue I'm only able to access ~550GB of it.

Any ideas on what would be causing this behaviour?

EDIT: Ran fsck on the USB drive and it found some errors and ended up returning some of the space, but I'm still missing quite a bit.

Also the fixes have made it so that it will return space after a deletion (tested by placing a 2GB file into the pool and then removing it, it's now returning the 2GB)

Which version of FreeNAS?

 

[Knowltey]

9.2.1, I ended up just recreating the pool and restoring from backup.

Do you have snapshots enabled? Sounds like you might have snapshots...

I did, however space still wasn't returned after that nor after deleting all of the snapshots. It was some sort of issue on the USB stick that became resolved once I ran the fsck, it just only returned ~half of what the issue actually took away and there was still a lot floating around unallocated. The fsck found a bunch of stuff that it had to correct.

Basically say I had 200GB of free space remaining and I put on a 2GB file, I'd then be left with 198GB free, then when I went to delete that file right afterwards since I was doing it as a test instead of just popping back up to 200GB like it had been doing for a long time instead it would actually lower down to 196GB.

If you had USB problems I'd recommend you reinstall FreeNAS and upload your config again. Having a bad OS disk isn't "cool".

 

[Knowltey]

Yep, that's actually what I'm doing right now.

Snapshot turned on! I was wondering where my TBs went to. I guess I can my free space in two weeks and see if it returns.

thanks again,

It is inappropriate to respond to a thread that is 10 months old just to add some anecdote that doesn't help solve the problem. In this case the OP destroyed the pool, so there was no reason to ever reply to this thread.
