Hi,
I noticed it is possible to use erasure code pool for RBD and CEPHFS
This got me thinking that I can deploy iSCSI luns on EC pools
However it appears it is not working
Anyone able to do that or have I misunderstood ?
Thanks
Steven
Here is the pool
ceph osd pool get ec_k4_m2 all
size: 6
min_size: 5
crash_replay_interval: 0
pg_num: 128
pgp_num: 128
crush_rule: ec_k4_m2
hashpspool: true
nodelete: false
nopgchange: false
nosizechange: false
write_fadvise_dontneed: false
noscrub: false
nodeep-scrub: false
use_gmt_hitset: 1
auid: 0
erasure_code_profile: EC_OSD
fast_read: 0
here is how I created an image just to make sure RBD is supported
rbd create rbd/image_ec1 --size 51200 --data-pool ec_k4_m2 --image-feature layering
here is what gwcli complains about
gwcli
/iscsi-target...sx01-657d71e0> cd /disks
/disks> create pool=ec_k4_m2 image=testec size=120G
Invalid pool (ec_k4_m2). Must already exist and be replicated
