Kaminario K2 iSCSI and FC arrays do not support concurrent operations. To avoid this, use locks and retry mechanism on each K2 requests. Also, use locks to avoid race conditions between attach and detach volumes.

fixes:
|
|
- Fixed concurrency issue in K2 iSCSI and FC Cinder drivers
|
|
due to possible race conditions between attach and detach
|
|
volumes and due to limitation from Kaminario K2 iSCSI and
|
|
FC arrays on concurrent operations.
|
|
To overcome array limitation, use locks and retry mechanism
|
|
on each K2 requests. To overcome race conditions, use locks
|
|
on initialize_connection and terminate_connection.
