We're using gluster in a production environement, 3 nodes (2 data + 1 arbiter).
One of our VM gluster fuse client is regularly crashing on a particular volume, we recently upgraded all nodes and client to 7.6 but client is still crashing.
All cluster nodes & client are Debian stretch (9.12), gluster was installed from our local gluster apt repository mirror and op-version is set to 70200.
Volume contains a lot of files & directories but performance doesn't really matters, it seems to crash during this command :
find logscli -mtime +1 -type f | tar c -T - -f - --remove-files | tar xpf - -C /drbd
Volume was remonted this morning with DEBUG log level, waiting for next crash.
Volume attributes are
