  "message": "dm mpath: add retry pg init\n\nThis patch allows a failed path group initialisation command to be retried.\n\nIt adds a generic MP_RETRY flag and a \"pg_init_retries\" feature to\ndevice-mapper multipath which limits the number of retries.\n\n1. A hw handler sends a path initialization command to the storage and\nthe command completes with an error code indicating the command\nshould be retried.\n\n2. The hardware handler calls dm_pg_init_complete() with MP_RETRY\nset in err_flags to ask the dm multipath core to retry.\n\n3. If the retry limit has not been exceeded, pg_init() is retried.\nOtherwise fail_path() is called.\n\nIf you are using the userspace multipath-tools or device-mapper-multipath\npackage, you can set pg_init_retries in the \u0027device\u0027 section of your\n/etc/multipath.conf file. For example:\n\nfeatures                \"2 pg_init_retries 7\"\n\nThe number of PG retries attempted is reported in the \u0027dmsetup status\u0027 output.\n\nSigned-off-by: Dave Wysochanski \u003cdwysocha@redhat.com\u003e\nAcked-by: Mike Christie \u003cmichaelc@cs.wisc.edu\u003e\nAcked-by: Chandra Seetharaman \u003csekharan@us.ibm.com\u003e\nSigned-off-by: Alasdair G Kergon \u003cagk@redhat.com\u003e\n",
