[Gluster-users] Warning: disk space on subvolume getting full - consider adding more nodes

[Peter B.]

Hi!

I've recently added another node to a gluster volume (glusterfs v3.4.6),
because it was getting full, but now I still receive the following warning
in the logs (/var/log/glusterfs/VOLUME-NAME.log) every 2-3 days:

0-dlp-storage-dht: disk space on subvolume 'dlp-storage-client-0' is
getting full (91.00 %), consider adding more nodes
[/quote]

Yes, the client-0 brick is indeed full, but shouldn't that be normal when
scaling out on-demand: One brick fills up, then you add a new one, etc?

I didn't do any re-balance, since I thought that it's optional and I
wouldn't want to move the stored data (~160 TB) around - at all - if not
necessary.


Is there anything I can do to make Gluster feel "good" with bricks filling
up, as long as there is sufficient space on other nodes/bricks?


Thank you very much in advance,
Pb
