Reattach gluster brick after rebuilt hypervisor
I have a gluster volume that was created using an older version 4.x of oVirt. This was so long ago I am not sure I remember how I did it except that I used the wizard and the built in ansible job. I recently rebuilt my system that is hyperconverged. The storage raid array (hardware backed) is in my hypervisor. The engine is a stand alone external device. I am now at ver 4.5.7 of Ovirt. I want to add my gluster brick back into the setup. I have reviewed the wiki notes but they presume a new build, not my scenario. From what I read and researched, I think I need to create a distributed brick. How do you do that with just a single system when there is no replication to other hosts? Can anyone share a general procedure? ##DIAGNOSTICS [root@vmh /]# mount ... /dev/mapper/gluster_vg_sda-gluster_lv_vmstore on /gluster_bricks/vmstore type xfs (rw,relatime,seclabel,attr2,inode64,logbufs=8,logbsize=256k,sunit=512,swidth=2048,noquota) [root@vmh /]# tail -n 1 /etc/fstab /dev/mapper/gluster_vg_sda-gluster_lv_vmstore /gluster_bricks/vmstore xfs defaults 0 0 [root@vmh /]# gluster volume create vmstore vmh.tourville.org:/gluster_bricks/vmstore volume create: vmstore: failed: The brick vmh.tourville.org:/gluster_bricks/vmstore is a mount point. Please create a sub-directory under the mount point and use that as the brick directory. Or use 'force' at the end of the command if you want to override this behavior. [root@vmh /]# gluster volume create vmstore vmh.tourville.org:/gluster_bricks/vmstore/vmstore volume create: vmstore: failed: /gluster_bricks/vmstore/vmstore is already part of a volume [root@vmh /]# tree /gluster_bricks/ /gluster_bricks/ └── vmstore └── vmstore └── 42c329c3-8eca-4748-af7a-f48aca494d72 ├── dom_md │ ├── ids │ ├── inbox │ ├── leases │ ├── metadata │ ├── outbox │ └── xleases ├── images │ ├── 019f828b-8f5d-47cf-bccd-7044402e7dd8 ... Do I need to force creation at this point? I just want to proceed cautiously at this point as I am not super confident with gluster. IE- [root@vmh /]# gluster volume create vmstore vmh.tourville.org:/gluster_bricks/vmstore force
