Riprendo quanto scritto nel suo messaggio del 29/08/2019...
Another possibilty is to convert the MBR to GPT
(sgdisk --mbrtogpt) and
give the partition its UID (also sgdisk). Then it could be linked by
its uuid.
and, in another email:
And I forgot that you can also re-create the journal
by itself. I can't
recall the command ATM though.
Ahem, i stated the jornal disk are also the OS disks, and i'm using old
server, so i think that converting to GPT will lead to an unbootable
node...
But, the 'code' that identify (and change permission) for journal dev
are PVE specific? or Ceph generic? I suppose the latter...
Also, i've done:
adduser ceph disk
and partition devices are '660 root:disk': why still i get 'permission
denied'?
Or if you are not in need of filestore OSDs, re-create
them as bluestore
ones. AFAICS, Ceph has laid more focus on bluestore and it might be
better to do a conversion sooner than later. (my opinion)
Not for now; bluestore migration need a bit more
time/study/knowledge...
