Dear ceph-users,
I’m trying to get the ceph monitor use a exclusive partition on my ssd drive. However, how should I prepare it?
I want to do something like this:
Ceph-deploy mon create mynode --mon-data /dev/sda5
Or
Ceph-deploy mon create mynode:/dev/sda5
/dev/sda5 is a 16GB partition on a 120GB ssd with mbr-ext2(???) formatted how should I continue…
Also
When preparing the OSD’s with a single dedicated platter disk per OSD like so:
Ceph-deploy disk zap mynode:/dev/sdd
And there is a corrupted GPT table (yes, I can do that :S ) a error is shown but the disk is not prepared.
Its not really clear what I’m zapping the disk with either ie: mbr/gpt and ext4,xfs or btrfs… it seems that fdisk doesn’t understand gpt, but disk zap tries to create a gpt table on it. I don’t think its really necessary for a 2TB to use GPT.
Its not clear whether or not a disk is zapped when using ceph-deploy osd prepare or ceph-deploy osd create either…
Then the journal for the osd disks can be set with something like
Ceph-deploy osd prepare mynode:/dev/sdd:/dev/sda6
But can I do this?
Or should I first mount it to the /var/lib/ceph/osd directory somewhere..
and what about formatting…
Can anyone clarify that for me?
Regards,
Johannes
