Hi,
We have developed a problem with Gluster reporting "No space left on
device." even though "df" of both the gluster filesystem and the
underlying bricks show space available (details below). Our inode usage
is between 1-3%. We are running gluster 3.7.11 in a distributed volume
across 2 servers (2 bricks each). We have followed the thread
https://lists.gluster.org/pipermail/gluster-users/2020-March/037821.html
but haven't found a solution yet.
Last night we ran a rebalance which appeared successful (and have since
cleared up some more space which seems to have mainly been on one
brick). There were intermittent erroneous "No space..." messages last
night, but they have become much more frequent today.
Any help would be greatly appreciated.
Thanks
