Perfect, thank you Adrien.

This is the clean way to handle this. But you can also use udev to do this at boot. From what I found on the mailing list and made working before using GUID :

cat > /etc/udev/rules.d/89-ceph-journal.rules << EOF

KERNEL=="sda?" SUBSYSTEM=="block" OWNER="ceph" GROUP="disk" MODE="0660"

KERNEL=="sdb?" SUBSYSTEM=="block" OWNER="ceph" GROUP="disk" MODE="0660"

KERNEL=="sdc?" SUBSYSTEM=="block" OWNER="ceph" GROUP="disk" MODE="0660"

EOF

Hi,

Is setting GUID is the only way to fix this ? I don't use GPT but MBR and I don't want to try conversion on production servers...

You should check that the owner of your ceph partitions (both journal and data) is 'ceph', otherwise the ceph user won't mount it.

You can simply do : chown ceph:disk /dev/sdc3

If this solve your issue you should set the GPT GUID [1] of the partitions with a tool like sgdisk to make this persistent across reboot.

I think only your journal is affected as ceph-disk does not prepare the partition (WARNING:ceph-disk:Journal /dev/sdc3 was not prepared with ceph-disk. Symlinking directly)
