Hi Vijay

Now it is unmounting every 30 mins !

The server log at /var/log/glusterfs/bricks/glusteratlas-brics001-gv0.log have this line only

2018-06-12 09:53:19.303102] I [MSGID: 115013] [server-helpers.c:289:do_fd_cleanup] 0-atlasglust-server: fd cleanup on /atlas/atlasdata/zgubic/hmumu/histograms/v14.3/Signal

There is no other information. Is there any way to increase log verbosity?

on the client

Hi

Since I have updated our gluster server and client to latest version 3.12.9-1, I am having this issue of gluster getting unmounted from client very regularly. It was not a problem before update.

Its a distributed file system with no replication. We have seven servers totaling around 480TB data. Its 97% full.

I am using following config on server


gluster volume set atlasglust features.cache-invalidation on
gluster volume set atlasglust features.cache-invalidation-timeout 600
gluster volume set atlasglust performance.stat-prefetch on
gluster volume set atlasglust performance.cache-invalidation on
gluster volume set atlasglust performance.md-cache-timeout 600
gluster volume set atlasglust performance.parallel-readdir on
gluster volume set atlasglust performance.cache-size 1GB
gluster volume set atlasglust performance.client-io-threads on
gluster volume set atlasglust cluster.lookup-optimize on
gluster volume set atlasglust performance.stat-prefetch on
gluster volume set atlasglust client.event-threads 4
gluster volume set atlasglust server.event-threads 4

clients are mounted with this option

defaults,direct-io-mode=disable,attribute-timeout=600,entry-timeout=600,negative-timeout=600,fopen-keep-cache,rw,_netdev

I can't see anything in the log file. Can someone suggest that how to troubleshoot this issue?




Can you please share the log file? Checking for messages related to disconnections/crashes in the log file would be a good way to start troubleshooting the problem.

Thanks,
Vijay
