hosted-engine --deploy failed (would not come up on my existing gluster storage). However, I realized no changes were written to my existing storage. So, I went back to trying to get my old engine running.
hosted-engine --vm-status is now taking a very long time (5+minutes) to return, and it returns stail information everywhere. I thought perhaps the lockspace is corrupt, so tried to clean that and metadata, but both are failing (--cleam-metadata has hung and I can't even ctrl-c out of it). How can I reinitialize all the lockspace/metadata safely? There is no engine or VMs running currently.... --Jim On Tue, May 29, 2018 at 9:33 PM, Jim Kusznir <[email protected]> wrote: > Well, things went from bad to very, very bad.... > > It appears that during one of the 2 minute lockups, the fencing agents > decided that another node in the cluster was down.
