You couldn't force start the volume because the brick
"nas-02-data:/datastore" doesn't have the "trusted.glusterfs.volume-id" .
From nas-02 node execute :
1. setfattr -n trusted.glusterfs.volume-id -v
0xfdff519085ef4cba9056a6bbbd8d6863 nas-02-data:/datastore
2. gluster volume start datastore1 force.

I don't understand what happened .

Hi Gandalf,
can you run the following command on the brick path?
"getfattr -d -e hex -m . /datastore" on both "nas-01-data" and
"nas-02-data" nodes.
This will let us know whether there is "trusted.glusterfs.volume-id" set.

hi thanks for the quick answer.
I'm running glusterfs 3.4.1
[root@nas-02 datastore]# gluster volume start datastore1 force
volume start: datastore1: failed: Failed to get extended attribute
trusted.glusterfs.volume-id for brick dir /datastore. Reason : No
data available
It seems that the .gluster directory is missing for some reason.
volume replace-brick datastore1 nas-01-data:/datastorenas-02-data:/datastore
commit force
To rebuild/replace the missing brick ?
I'm quite new with glusterfs
Thanks

Hi have setup a two node replication glusterfs. After the initial
installation the "master" node was put into the datacenter and after
two week we moved the second one also to the datacenter.
But the sync has not started yet.

Which version of glusterfs are you running?
volume status suggests that the second brick (nas-02-data:/datastore)
is not running.
Can you run "gluster volume start <volname> force" in any of these
two nodes and try again?
Then you would also required to run `find . | xargs stat` on the
mountpoint of the volume. That should trigger the self heal.
There are no active volume tasks
I would like to run on the "slave" gluster volume sync nas-01-data
datastore1
BTW, There is no concept of "master" and "slave" in afr
(replication). However there is concept of "master volume" and "slave
volume" in gluster geo-replication.
But then the virtual machines hosted will be unavailible is there
another way to start the replication ?
Thanks
