Hi, I'm trying to set up an erasure coded pool, as described in the Ceph docs:
http://ceph.com/docs/firefly/dev/erasure-coded-pool/ Unfortunately, creating a pool like that gives me the following error: # ceph osd pool create ecpool 12 12 erasure Error EINVAL: cannot determine the erasure code plugin because there is no 'plugin' entry in the erasure_code_profile {}failed to load plugin using profile default I noticed that the default profile appears to be empty: # ceph osd erasure-code-profile get default # I tried setting the default profile right, but I'm not allowed: # ceph osd erasure-code-profile set default plugin=jerasure technique=reed_sol_van k=2 m=1 Error EPERM: will not override erasure code profile default So I set a new profile with the same configuration: # ceph osd erasure-code-profile set k2m1 plugin=jerasure technique=reed_sol_van k=2 m=1 # ceph osd erasure-code-profile get k2m1 directory=/usr/lib64/ceph/erasure-code k=2 m=1 plugin=jerasure technique=reed_sol_van So, that worked :) However, I still can't use it to create a pool: # ceph osd pool create test123 100 100 erasure k2m1 Error EIO: failed to load plugin using profile k2m1 I double checked that the directory is correct, and it is: # ls -al /usr/lib64/ceph/erasure-code/libec_jerasure.so lrwxrwxrwx. 1 root root 23 12 jun 21:36 /usr/lib64/ceph/erasure-code/libec_jerasure.so -> libec_jerasure.so.2.0.0 It does contain the jerasure library, so now I'm at a loss. What am I doing wrong? By the way, this is ceph-0.80.1. Thanks, Erik. _______________________________________________ ceph-users mailing list ceph-users@lists.ceph.com http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
