Loic,
Thank you very much for the partprobe workaround. I rebuilt the cluster using
94.2.
I've created partitions on the journal SSDs with parted and then use ceph-disk
prepare as below. I'm not seeing all of the disks with the tmp mounts when I
check 'mount' but I also don't see any of the mount directory mount points at
/var/lib/ceph/osd. I'm see the following output from prepare. When I attempt to
'activate' it errors out saying the devices don't exist.
ceph-disk prepare --cluster ceph --cluster-uuid

Caution: invalid backup GPT header, but valid main header; regenerating
backup header from main header.
