Description

Hi,

can't create a simple filestore with help of ceph-disk under ubuntu trusy, please have a look on this...

root@luminous-node1:~# ceph-disk prepare --filestore --cluster ceph --cluster-uuid 1da14634-950f-4ebf-90c5-6dd7d906c071 --fs-type xfs /dev/sde
/usr/lib/python2.7/dist-packages/ceph_disk/main.py:5653: UserWarning:
*******************************************************************************
This tool is now deprecated in favor of ceph-volume.
It is recommended to use ceph-volume for OSD deployments. For details see:

ceph-volume is currently not a option because he has another open bug http://tracker.ceph.com/issues/22840 which makes it impossible to create a filestore in the normal way.

At the moment we do this manually, which is error prone.

Best regards
Enrico

I would suspect that something is strange about the disk (non-GPT partition table perhaps?), and you're getting less-than-helpful output from sgdisk.

Hi John,

you are sure, i mean '--change-name=2:ceph journal' isn't in quotes as far as i can see, but it should be maybe, so i tested this manually with quoted naming and it works.

Currently i did a test on a fresh ubuntu xenial box...

root@luminous-node3:/var/lib/ceph/mon/ceph-luminous-node3# /sbin/sgdisk --new=2:0:+10M --change-name='2:ceph journal' --mbrtogpt -- /dev/sdb
Setting name!
partNum is 1
REALLY setting name!
The operation has completed successfully.
root@luminous-node3:/var/lib/ceph/mon/ceph-luminous-node3# sgdisk -p /dev/sdb
Disk /dev/sdb: 2097152 sectors, 1024.0 MiB
Logical sector size: 512 bytes

... seems it works if the name is in quotes, also tested this without quotes without success :(.
