Subject: cephfs <fs> set_layout -p 3 ... EINVAL
Date: Tue, 16 Jul 2013 13:54:48 +0200 [thread overview]
Message-ID: <20130716115448.GA23760@oder.mch.fsc.net> (raw)
I followed the description
http://www.sebastien-han.fr/blog/2013/02/11/mount-a-specific-pool-with-cephfs/
... to change the pool assigned to cephfs:
# ceph osd dump | grep rule
pool 0 'data' rep size 2 min_size 1 crush_ruleset 0 object_hash rjenkins pg_num 10304 pgp_num 10304 last_change 1 owner 0 crash_replay_interval 45
pool 1 'metadata' rep size 2 min_size 1 crush_ruleset 1 object_hash rjenkins pg_num 10304 pgp_num 10304 last_change 1 owner 0
pool 2 'rbd' rep size 2 min_size 1 crush_ruleset 2 object_hash rjenkins pg_num 10304 pgp_num 10304 last_change 1 owner 0
pool 3 'SSD-group-2' rep size 2 min_size 1 crush_ruleset 3 object_hash rjenkins pg_num 3300 pgp_num 3300 last_change 299 owner 0
pool 4 'SSD-group-3' rep size 3 min_size 1 crush_ruleset 3 object_hash rjenkins pg_num 3300 pgp_num 3300 last_change 302 owner 0
pool 5 'SAS-group-2' rep size 2 min_size 1 crush_ruleset 4 object_hash rjenkins pg_num 3300 pgp_num 3300 last_change 306 owner 0
pool 6 'SAS-group-3' rep size 3 min_size 1 crush_ruleset 4 object_hash rjenkins pg_num 3300 pgp_num 3300 last_change 309 owner 0
# cephfs /mnt/cephfs/ show_layout
layout.data_pool: 0
layout.object_size: 4194304
layout.stripe_unit: 4194304
layout.stripe_count: 1
# mount | grep ceph
10.10.38.13:/ on /mnt/cephfs type ceph (name=admin,key=client.admin)
# cephfs /mnt/cephfs/ set_layout -p 3 -u 4194304 -c 1 -s 4194304
Error setting layout: Invalid argument
Is this a bug in the current release ?
# ceph -v
ceph version 0.61.4 (1669132fcfc27d0c0b5e5bb93ade59d147e23404)
How can this issue be solved ?
Kind Regards,
Dieter Kasper
