Hi,
Having timeout problems with my cluster, I try to finsh, recreate OSDs
that failed.
My config is hybrid with 17 HDD and 1 SSD by server.
My OSD spec is the standard :
service_type: osd
service_id: throughput_optimized
service_name: osd.throughput_optimized
placement:
host_pattern: '*'
spec:
data_devices:
rotational: 1
db_devices:
rotational: 0
objectstore: bluestore
encrypted: true
filter_logic: AND
When I remove an OSD with :
ceph orch osd rm ID --zap
It is finaly re-created, but without DB device.
And I can see the ceph-volume commands :
Zapping :
cephadm ['--image',
'quay.io/ceph/ceph@sha256:7c69e59beaeea61ca714e71cb84ff6d5e533db7f1fd84143dd9ba6649a5fd2ec',
'--timeout', '2395', 'ceph-volume', '--fsid',
'8ec7575a-7de5-11f0-a78a-246e96bd90a4', '--', 'lvm', 'zap', '--osd-id',
'82', '--destroy']
Recreate :
cephadm ['--env', 'CEPH_VOLUME_OSDSPEC_AFFINITY=throughput_optimized',
'--image',
'quay.io/ceph/ceph@sha256:7c69e59beaeea61ca714e71cb84ff6d5e533db7f1fd84143dd9ba6649a5fd2ec',
'--timeout', '2395', 'ceph-volume', '--fsid',
'8ec7575a-7de5-11f0-a78a-246e96bd90a4', '--config-json', '-', '--',
'lvm', 'batch', '--no-auto', '/dev/sde', '--dmcrypt', '--osd-ids', '82',
'--yes', '--no-systemd']
I think it should have the argument --db-devices ?
I can see that option when the OSD spec was applied, it launch for all
drives on the host :
cephadm ['--env', 'CEPH_VOLUME_OSDSPEC_AFFINITY=throughput_optimized',
'--image',
'quay.io/ceph/ceph@sha256:7c69e59beaeea61ca714e71cb84ff6d5e533db7f1fd84143dd9ba6649a5fd2ec',
'--timeout', '2395', 'ceph-volume', '--fsid',
'8ec7575a-7de5-11f0-a78a-246e96bd90a4', '--config-json', '-', '--',
'lvm', 'batch', '--no-auto', '/dev/sda', '/dev/sdb', '/dev/sdc',
'/dev/sdd', '/dev/sde', '/dev/sdf', '/dev/sdg', '/dev/sdh', '/dev/sdi',
'/dev/sdj', '/dev/sdk', '/dev/sdl', '/dev/sdm', '/dev/sdn', '/dev/sdo',
'/dev/sdp', '/dev/sdq', '--db-devices', '/dev/sdr', '--dmcrypt',
'--yes', '--no-systemd']
There is the --db-devices argument.
Is it a bug or I do it wrong ?
I have several OSD that are now without DB device, I want to recreate
them with the DB device.
And also, I want that every time a new drive is created, it will be with
a DB device, or fails if no room, but not create without DB device if my
OSD SPEC tells it.
