Storage space issue

[Charlie86]

Hi,

I am running FreeNAS-11.1-U1

5x3TB in RaidZ

I have 719GB free space so I am getting warning that 90% of storage is used. Today I delete about 0.8TB but system is still on warning of 90% used space. And even I storage tab it still shows only 719GB of free space.

How can I fix that, I try to reboot server but that did not solve problem.

Thank you.

Do you snapshot?

In snapshot tab there is 550 pages of snapshots. I am greenhorn so I do not know what to do with them,.. :) Do I need to use them or just delete it?

In snapshot tab there is 550 pages of snapshots.

There's your problem. You can manually delete them, just wait for them to expire, add more storage, or run a script to delete all the automatic snapshots. In the latter case, the script would look like this:

Code:

#!/bin/bash
for std in `zfs list -H -o name -t snapshot | grep -- '@auto-'`
do
	echo "zfs destroy $std"
	zfs destroy $std
done

Hi thank you both. Deleted all snapshots and now I am at 1.8GB of free space. If I understand correctly snapshot is something like time machine in OS X world. So you can restore data, that was already deleted?

Also, where did I "lose" space in screenshot below?
Volume have 10.1TB but dataset only have 8.1TB?

Note that in this example, there are two datasets named volume1. The first represents the ZFS pool and its Used and Available entries reflect the total size of the pool, including disk parity. The second represents the implicit or root dataset and its Used and Available entries indicate the amount of disk space available for storage.

Check snapshots if you have them. I got caught out a few times with these, kinda like "hidden" space usage. You don't really see it in the GUI.

OK,

I read dosc you posted, and understand where is "missing" space.

Hint: TB vs. TiB :)

thank you, once again.

@leenux_tux: yes it was snapshots. Thank you.
