Re: OSD & JOURNAL not associated - ceph-disk list ?

Florent,

I had similar issues, even when using ceph-disk. I've fixed it by making sure the part-UUID of the journal partition is the only thing in the file /var/lib/ceph/osd/{cluster}-{OSD#}/journal_uuid and made sure that the /var/lib/ceph/osd/{cluster}-{OSD#}/journal was a symlink to the correct part-uuid partition.

Ceph-disk list should map the journal and the data disks after that.

Hi,

I would like to separate OSD and journal on 2 différent disks so I have :

1 disk /dev/sde (1GB) for journal => type code JOURNAL_UUID =         '45b0969e-9b03-4f30-b4c6-b4b80ceff106'
1 disk /dev/sdd (5GB) for OSD => type code OSD_UUID =             '4fbd7e29-9d25-41b8-afd0-062c0ceff05d'

I execute below commands :

FOR JOURNAL :
sgdisk --new=1:0:1023M --change-name="1:ceph journal" --partition-guid=1:e89f18cc-ae46-4573-8bca-3e782d45849c --typecode=1:45b0969e-9b03-4f30-b4c6-b4b80ceff106 -- /dev/sde

FOR OSD:
sgdisk --new=1:0:5119M --change-name="1:ceph data" --partition-guid=1:7476f0a8-a6cd-4224-b64b-a4834c32a73e --typecode=1:4fbd7e29-9d25-41b8-afd0-062c0ceff05d -- /dev/sdd

And I'm preparing OSD :
ceph-disk prepare --osd-uuid 7476f0a8-a6cd-4224-b64b-a4834c32a73e --journal-uuid e89f18cc-ae46-4573-8bca-3e782d45849c --fs-type xfs --cluster ceph -- /dev/sdd1 /dev/sde1


After that, I don’t see relation between /dev/sde1 & /dev/sdc1

root@falcon:/srv/ceph01adm001/data/cluster-ceph01# ceph-disk list
/dev/sdd :
 /dev/sdd1 ceph data, prepared, cluster ceph
/dev/sde :
 /dev/sde1 ceph journal

Is it normal ?

Thanks


Florent Monthel
