Subject: [PATCH] multipathd: fix missing persistent reseravtion for active
|
|
path
|
|
|
|
There are two paths(sucu as sda and adb) for one LUN. The two
|
|
paths log in, but before the two uevents have been processed
|
|
(for example there are many uevent), users use multipathd add
|
|
path /dev/sda to cause mpatha and use mpathpersist -o -I to
|
|
register prkey for mpatha. The add map uevent is after add path
|
|
uevent, the the uevent(add sdb) will delay and missing persistent
|
|
reseravtion check.
|
|
|
|
Here, we add persistent reseravtion check in update_map() which
|
|
is called ev_add_map().
