Hi,
We have a cluster whose common storage is a gluster volume
consisting of 5 bricks residing on 3 servers.
- Gluster volume machines
- mseas-data2: CentOS release 6.8 (Final)
- mseas-data3: CentOS release 6.10 (Final)
- mseas-data4: CentOS Linux release 7.9.2009 (Core)
- Client machines
- CentOS Linux release 7.9.2009 (Core)
More details on the gluster volume are included below.
We were recently trying to gunzip a file on the gluster volume and
got a "Transport endpoint is not connected" even though every
test we try shows that gluster is fully up and running fine. We
traced the file to brick 3 in the server mseas-data3. We have
included the relevant portions of the various log files on the
client (mseas) where we were running the gunzip command and the
server hosting the file (mseas-data3) below the gluster
information
What can you suggest we do to further debug and/or solve this
issue?
Thanks
Pat
