[Gluster-users] Disk space usage

[Thibault Godouet]

I have a replicated Gluster 3.7.3 volume composed of two bricks, each on a
different server.

If I mount the volume as NFS (because it is a lot faster than FUSE for du),
and do a 'du -h' on this, it returns 56GB.

Yet the disk usage on each brick is quite a lot higher:

- a 'du -h' gives me 104GB, 99% (or more) of it being .glusterfs

- a 'df -h' gives me 85GB (and there is nothing else on the partition)



I'd be interested to hear if someone knows why du and df give me different
values, but even more interested to know why df reports 85GB rather than
close to 56GB (the actual size of the data in the volume).



Is this expected?

If not, is there a way to make it clear the extra space and go down to 56GB
disk usage on each brick?



Thanks,

Thibault.
