HI,
In my Distriuted-Replicated volume [ 2 x 3 = 6] used as a data domain for oVirt hypervisor, I had a trouble with used space :
It was a previous Replicated 1 x 3 = 3 volume extended by adding one brick (one disk) in each server to recharge a 2 x 3 = 6 volume.
Df -h on the mount point give à 98% used volume (see below)
Filesystem Size Used Avail Use% Mounted on ovirt1.pmmg.priv:/data 3.4T 3.3T 82G 98% /rhev/data-center/mnt/glusterSD/ovirt1.pmmg.priv:_data
But : du -hs on this folder give me a really different amount of data :
du -hs /rhev/data-center/mnt/glusterSD/ovirt1.pmmg.priv\:_data
1.4T /rhev/data-center/mnt/glusterSD/ovirt1.pmmg.priv:_data
And of course just a small hidden folder (.trashcan nearly empty in this mount point) :
du -hs /rhev/data-center/mnt/glusterSD/ovirt1.pmmg.priv\:_data/.trashcan
1.2M /rhev/data-center/mnt/glusterSD/ovirt1.pmmg.priv:_data/.trashcan
I don’t known how to free space in this volume and why such a difference between DU and DF ? Are my data replicated on the 6 bricks ?
Any clues will be appreciated.
Thank's |
