    Description

      Looks like LU-9372 has regression on OPA enviroment and somehow when test_req_buffer_pressure is enabled (test_req_buffer_pressure=1) on OSS or MDS, client never reconnect and no trigger Lustre recovery.

      [root@es14k-vm1 ~]# lustre_rmmod 
      [root@es14k-vm1 ~]# vi /etc/modprobe.d/lustre.conf
      
      options ptlrpc test_req_buffer_pressure=1
      
      [root@es14k-vm1 ~]# mount -t lustre /dev/ddn/scratch0_ost0000 /lustre/scratch0/ost0000
      
      [root@es14k-vm1 ~]# cat /proc/fs/lustre/obdfilter/scratch0-OST0000/recovery_status 
      status: WAITING_FOR_CLIENTS
