Phantom Used Space

[House Of Cards]

I have a dataset that I'm moving data from. Browsing the NFS shares with "show hidden files" shows everything is empty. I deleted all my snapshots and the pool interface still shows it has about 50GB of data in it. Is there a ZFS command to show what is using this space, or force a recalculation?

Thanks!

To check your pool capacity:

Code:

zpool list

To check your datasets usage:

Code:

zfs list

To check your snapshots usage:

Code:

 zfs list -t snap

To check how much space a folder/directory takes (beware, this could take a long time if you have a lot of data under that folder):

Code:

du -hd0 /path/to/folder

 

[House Of Cards]

du -hd0 /path/to/folder

This returns 2.0 KB, the interface shows 44.8 GB. I'm trying to make sure I'm not missing any files before I nuke the dataset. Might have to reboot here shortly and see if that clears up this buggy interface reporting...

Are there any nested datasets under that path. du isn't really built for ZFS so it may not report that correctly and you should probably use the output of zfs list instead.

If you want a comprehensive list:

Code:

zfs list -r -t filesystem -o space

This will help you narrow down where data still exists.

A reboot fixed it. The GUI wasn't updating properly, apparently.
