ReadyNAS reports not enough space

My ReadyNAS 524X reports (data shows a red bar) that there is only 481 GB available out of 8.17 TB of space. I have 4 3 TB drives installed in the unit, using RAID 5. I am running on a Mac.
When I use Finder to add up all the folders under "data" on the network, it adds up to only 3 TB. I have rebooted both the Mac and the ReadyNAS.
Any ideas why there is such a discrepancy?

Thank you for your comments, Sandshark. As a matter of fact, in my case, deleting snapshots and rebalancing did free up that much space. I don't know why it worked, but it did. 🙂

Re: ReadyNAS reports not enough space
I recently read about rebalancing on the ReadyNAS, which may free up space, but I don't seem to have that option. I have the latest firmware (6.10.2), but Settings does not have an option that I can see for scheduling a rebalance operation.
Anybody have this problem?

Re: ReadyNAS reports not enough space
On the Volumes page of the GUI, you can see if some of that space is taken up by snapshots and you can also use the gear icon to do a balance. But it would be unusual for a balance to free up that much space.

Yes. I think the first step is to see how much space is in snapshots.
@OldTimerGuy are you using the NAS to store time machine backups?

No, I am not using the NAS to store Time Machine backups. I use an attached external hard drive. But deleting snapshots and rebalancing worked in my case. Thank you for your comments.

Re: ReadyNAS reports not enough space
It is likely that the snapshot deletion was the main thing that released the free space. Reclaining of free space after deleting snapshots can take a while, and a balance will speed that up.

Thank you, Sandshark. I will delete the snapshots more often now.

If you switch to "Custom" snapshots you can explicitly set the retention. I find that to be an easier way to manage the snapshot space than going in and manually deleting the "Smart" snapshots.
If you switch to this, then I suggest starting with 3 months of retention for every share, and monitor the overall snapshot space. Then adjust it to acheive the balance you want.
There is also a setting there to only make snapshots when the main share changes - which I also recommend setting.

Great idea StephenB! I'll give it a try.
