HI,
After some more poking around in the logs (specifically the brick logs)
- brick1 & brick2 have both been recording "No space left on device" messages today (as recently at 15 minutes ago)
- brick3 last recorded a "No space left on device" message last night around 10:30pm
- brick4 has no such messages in its log file
Note brick1 & brick2 are on one server, brick3 and brick4 are on the second server.

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
