Hi,
I was trying the scenario where i have partitioned my drive (/dev/sdb)
into 4 (sdb1, sdb2 , sdb3, sdb4) using the sgdisk utility:
# sgdisk -z /dev/sdb
# sgdisk -n 1:0:+1024 /dev/sdb -c 1:"ceph journal"
# sgdisk -n 1:0:+1024 /dev/sdb -c 2:"ceph journal"
# sgdisk -n 1:0:+4096 /dev/sdb -c 3:"ceph data"
# sgdisk -n 1:0:+4096 /dev/sdb -c 3:"ceph data"
checked the partition with lsblk and it has created the partitions as
expected.
im using the ceph-disk command to create the osd's:
# ceph-disk prepare --cluster ceph /dev/sdb3 /dev/sdb1
prepare_device: OSD will not be hot-swappable if journal is not the
same device as the osd data
prepare_device: Journal /dev/sdb1 was not prepared with ceph-disk.
Symlinking directly.
set_data_partition: incorrect partition UUID:
0fc63daf-8483-4772-8e79-3d69d8477de4, expected
['4fbd7e29-9d25-41b8-afd0-5ec00ceff05d',
'4fbd7e29-9d25-41b8-afd0-062c0ceff05d',
'4fbd7e29-8ae0-4982-bf9d-5a8d867af560',
'4fbd7e29-9d25-41b8-afd0-35865ceff05d']
*snipsnap*
CEPH OSD and journal partitions have a certain partition type UUID, as
the message suggests. To avoid problems with OSD autodetection at boot
time you need to change the UUID.
