Hi,
I am unable to create OSD because "
Device /dev/sdc not found (or ignored by filtering)."
I tried using the ceph-volume ( on the host) as well as ceph-deploy ( on the admin node)
The device is definitely there
Any suggestions will be greatly appreciated
Note
I created the block-db and respectively block-wal partitions using below
for i in {2,4,6,8}; do echo $i; /sbin/sgdisk --new=$i:0:+30G --change-name=$i:'ceph DB' --typecode=$i:89c57f98-2fe5-4dc0-89c1-f3ad0ceff2be --mbrtogpt -- /dev/sda;done
for i in {1,3,5,7}; do echo $i; /sbin/sgdisk --new=$i:0:+1G --change-name=$i:'ceph WAL' --typecode=$i:89c57f98-2fe5-4dc0-89c1-f3ad0ceff2be --mbrtogpt -- /dev/sda;done
