Hi,
we had a 2 node glusterfs cluster.
we had a 2x2 Distributed-Replicate volume on it.
It was:
Brick1: s20gfs.ovirt:/gluster/VOL/brick1
Brick2: s21gfs.ovirt:/gluster/VOL/brick2
Brick3: s20gfs.ovirt:/gluster/VOL/brick3
Brick4: s21gfs.ovirt:/gluster/VOL/brick4
We added more nodes to the cluster. So I wanted to redistribute the
bricks on the nodes.
I added 2 new bricks to the volume.
gluster volume add-brick VOL s22gfs.ovirt:/gluster/VOL/brick2
s23gfs.ovirt:/gluster/VOL/brick3
then I removed 2 old bricks
gluster volume remove-brick VOL s20gfs.ovirt:/gluster/VOL/brick1
s21gfs.ovirt:/gluster/VOL/brick2 start
checked the status
gluster volume remove-brick VOL s20gfs.ovirt:/gluster/VOL/brick1
s21gfs.ovirt:/gluster/VOL/brick2 status
when it was completed and I saw data on the new bricks I run:
gluster volume remove-brick VOL s20gfs.ovirt:/gluster/VOL/brick1
s21gfs.ovirt:/gluster/VOL/brick2 commit
Result:
some files missing from the volume. Those file are still on the removed
bricks.
First question. Have I followed a wrong procedure?
Second question. How to restore those files? I can't re-add back those
brick to the volume because it tolds me:
volume add-brick: failed: /gluster/VOL/brick1 is already part of a volume
If I use the force option I get the old files or they get erased?
Should I rsync from the "unmounted" brick to the "mounted" volume or to
an "umounted" brick that is part of the volume?
Regards,
