Dear Gluster-Community,
I created a test-environment to test a gluster volume with
replica 3.
Afterwards, I am able to manually mount the gluster volume
using FUSE.
mount command:
mount -t glusterfs -o
backup-volfile-servers=gluster01:gluster02
gluster00:/ifwFuse /mnt/glusterfs/ifwFuse
Just for a testing purpose, I shutdown two (arbitrary)
bricks and one brick keeps still online
and accessible via ssh. If I poweroff the two machines, I
immediately get the following error message:
ls: cannot open directory .: Transport
endpoint is not connected
From my understanding of replica 3, even if
two bricks are broken the client should be able to
have access to the data.
In replica 3, 2 out of 3 bricks must be up for
allowing access. IoW, client-quorum must be met. Otherwise you
would get ENOTCONN like you observed.
Actually, I don't know how to solve that
issue. Any idea is welcome!
You could disable client-quorum but it is
strongly advised not to do so in order to prevent split-brains
(https://docs.gluster.org/en/v3/Administrator%20Guide/Split%20brain%20and%20ways%20to%20deal%20with%20it/).
Hope that helps.

If you need any log-file as further
information, just give me a hint!
Thanks in advance.
