I think this could be misaligned writes.
Is it multiple of 4k ?? Its just a wild guess.

thanks,

Hello,

I use librados C API rados_append() to append object data in erasure coded pool, it always return -95 (Operation not supported). 
Buf if i use the same code to append object data in replicated pool, it works fine.
Does erasure coded pool not support append write?

Below is my erasure coded pool setting. 
pool 2 'Edata_pool' erasure size 6 min_size 4 crush_ruleset 8 object_hash rjenkins pg_num 512 pgp_num 512 last_change 139 flags hashpspool stripe_width 4096

Any advice will appreciate.
Hercules
