Hi,

I have a strange situation with a simple zfs filesystem, no compression,
no dedup, just a bare zfs.
It runs almost 1T of imap storage, up since 2012.

Now i found this strange du issues in some folders:

/sonicle/var/spool/imap/user/edp$ du -h
...
277M ./F1/F2
622M ./F1
...

then

/sonicle/var/spool/imap/user/edp : du -h F1
1.5G F1/F2
1.8G F1

This last one is the correct one.
Looks like sizes are misleaded when using du on the current tree rather
than on a specific folder...
Just for some folders...

Any idea?

Gabriele

Hi,

zfs snapshots enabled?
F1/F2 mounted under F1?

I do not think that du is reliable command for zfs... I would rather use:
zfs list -o compression,compressratio,used,avail,refer,canmount,mountpoint,name | grep -E "HOME|F(1|2)"

This is w/o having any knowledge about complexisty of file systems created...

HTH
Regards.
