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,

Hint: Some lines were ellipsized, use -l to show in full.
but when i reboot the node , the osd doesn't comes up automatically!!

# systemctl start [email protected]
Job for [email protected] failed because start of the service was
attempted too often. See "systemctl status [email protected]" and
"journalctl -xe" for details.
To force a start use "systemctl reset-failed [email protected]" followed
by "systemctl start [email protected]" again.
But if i do it with the single osd per drive, it works fine....
Anyone else faced the same issue anytime??
Thanks,
Sandeep
