* gluster-block: use targetcli interactive modePrasanna Kumar Kalever2017-08-281-0/+23
| | | | | | | | | | | | | | | | | | Currently, on each targetcli create call, rtslib will rebuild its bs_cache, so as the /sys/kernel/config/target/core dir gets more entries this takes longer and longer to scan. Hence using repetitive targetcli in the block create for creating iqn, backend, setting acls, setting globals will induce too much delay in block create. As the number of blocks on the node increases, the delay will be too longer. This does not happen if we open targetcli in interactive mode and just do multiple create commands form it, since the bs_cache is build once.
