[Gluster-users] Erroneous "No space left on device." messages
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.
