[Gluster-users] Community to supported

[Colin Coe]

Hi all

We've been running community supported gluster for a few years and now
we've bought support subscriptions for RHGS.

We currently have a 3 node system (2 replicas plus quorum) in production
hosting several volumes with a TB or so of data.

I've logged a support ticket requesting the best path forward to migrating
from the community version to the RH supported version and was told to
re-install. Obviously I'd rather not do that as it will be very disruptive.

Is there a way to migrate from gluster to RHGS without re-installing?

Thanks

Hi all

I did some basic testing and did a Gluster to RHGS using

Built three new VMs (devfil01, devfil02, devfil03) and installed community
gluster version 3.8.7. using devfil01, added all three nodes to the pool -
peer probe devfil02 - peer probe devfil03 Created a volume matching the
basic setup of production - gluster volume create testvol replica 3 arbiter
1 devfil01:/bricks/brick1/brick devfil02:/bricks/brick1/brick
devfil03:/bricks/brick1/brick On devfil03 (arbiter first) - systemctl stop
glusterd - pkill glusterfs - yum erase $(rpm -qa | grep glusterfs) -
rhn-channel -r -c el-x86_64-glusterfs-7 # community gluster - rhn-channel
-a -c rhn-channel -a -c rhel-x86_64-server-7-rh-gluster-3 -c
rhel-x86_64-server-7-rh-gluster-3-nfs -c
rhel-x86_64-server-7-rh-gluster-3-samba - yum install glusterfs-server -y -
systemctl restart glusterd Repeat for devfil02 Repeat for devfil01

Any thoughts on this process? Anything I'm missing or could do a better
way?

Thanks

Hi Colin,

I think it would be ideal to vet this process with your Red Hat support
channel. It is difficult to provide authoritative advice on any downstream
product based on upstream GlusterFS in this forum.

Thanks,
Vijay

Hi

The initial response I got from GSS was re-install which I why I posted
here. I used the process I outlined above and it seemed to work but I was
looking for advice/war stories.

Thanks
