Sorry, i came back to this topic because i've done some more tests.
Seems that 'pveceph' tool have some trouble creating OSD with journal
on ''nonstandard'' partition, for examply on a MD device.
A command like:
pveceph createosd /dev/sde --journal_dev /dev/md4
fail mysteriously (OSD are added to the cluster, out and down, but on
the node even the service get not created, eg, there's nothing to
restart).
Disks get partitioned/formatted (/dev/sde, but also /dev/md4).
If instead i create on the device a GPT partition, for example of type
Linux, i can do:
pveceph createosd /dev/sde --journal_dev /dev/md4p1
and creation of the OSD work flawlessy, with only a single warning
emitted:
WARNING:ceph-disk:Journal /dev/md4p1 was not prepared with ceph-disk.
Symlinking directly.
But journal work as expected.
I make a note. Thanks.
