[LU-571] Remove Parallel AST limits

• Type: Technical task
• Resolution: Fixed
• Priority: Minor
• Fix Version/s: Lustre 2.2.0
• Assignee: Jinshan Xiong (Inactive)
• Reporter: Jinshan Xiong (Inactive)

Description

Imperative recovery has to notify the clients as soon as possible. However, the limitation of parallel ast is set to 200 each time, this causes a problem for IR since it will take:

(# of client) * (AST_RPC_TIMEOUT) / 200

at most for the MGS to notify all clients, and the recovery time window may have passed this will cause all clients will be evicted.
