Hi,
The client logs indicates that the mount process has crashed.
Please try mounting the volume with the volume option lru-limit=0 and see if it still crashes.
Thanks,
Nithya

Good morning,
we currently transfer some data to a new glusterfs volume; to check
the throughput of the new volume/setup while the transfer is running i
decided to create some files on one of the gluster servers with dd in
loop:
while true; do dd if=/dev/urandom of=/shared/private/1G.file bs=1M
count=1024; rm /shared/private/1G.file; done
/shared/private is the mount point of the glusterfs volume. The dd
should run for about an hour. But now it happened twice that during
this loop the transport endpoint gets disconnected:
dd: failed to open '/shared/private/1G.file': Transport endpoint is
not connected
rm: cannot remove '/shared/private/1G.file': Transport endpoint is not connected
In the /var/log/glusterfs/shared-private.log i see:

The whole output can be found here: https://pastebin.com/qTMmFxx0
gluster volume info here: https://pastebin.com/ENTWZ7j3
After umount + mount the transport endpoint is connected again - until
the next disconnect. A /core file gets generated. Maybe someone wants
to have a look at this file?
