Hi, I am interested about these steps too, for a clean an straighforward procedure. Althought this plan looks pretty good, i am still wondering:
Step 4 Backup all gluster config files - could you please let me know what would be the exact location(s) of the files to be backed up ? Step 6 Install glusterfs, restore the configs from step 4 - would the configs work with this version ? - would in theory gluster get back to a previous balanced state ? Step 9 Deploy the new HE on a new Gluster Volume, using the backup/restore procedure for HE. - this assumes to firstly create a new volume based on some aditional new disks or lvms, right ? Sorry if maybe I'm missing somethings due to my lack of knowledge.
