When creating EC fs, create replicated pool as primary pool and ec pool as secondary pool, creating ec pool as primary is not encouraged and it will lead to failure. Also, changing the pool name in storageclass-ec file. Closes: https://github.com/rook/rook/issues/8210 Signed-off-by: subhamkrai <srai@redhat.com>
