Hi all,
I have sporadic VM going down which files are on gluster FS.
If I look at the gluster logs the only events I find are:
/var/log/glusterfs/bricks/data-brick2-brick.log

The strange part is that I cannot seem to find any other error.
If I restart the VM everything works as expected (it stopped at ~9.51
UTC and was started at ~10.01 UTC) .
This is not the first time that this happened, and I do not see any
problems with networking or the hosts.
Gluster version is 3.8.11
this is the incriminated volume (though it happened on a different one too)
Volume Name: datastore2
Type: Replicate
Volume ID: c95ebb5f-6e04-4f09-91b9-bbbe63d83aea
Status: Started
Snapshot Count: 0
Number of Bricks: 1 x (2 + 1) = 3
Transport-type: tcp
Bricks:
Brick1: srvpve2g:/data/brick2/brick
Brick2: srvpve3g:/data/brick2/brick
Brick3: srvpve1g:/data/brick2/brick (arbiter)
Options Reconfigured:
nfs.disable: on
performance.readdir-ahead: on
transport.address-family: inet
Any hint on how to dig more deeply into the reason would be greatly
appreciated.
Alessandro
