Path device fds were changed to be opened read/write when the mpathpersist code was added. However, I have talked with Vijay, and this doesn't appear to be necessary for mpathpersist to work correctly. If the path fds are opened read/write, when the are closed a change uevent is triggered, which was causing problems during shutdown with LVM on top of multipath devices. This patch reverts them to being read-only again. Signed-off-by: Benjamin Marzinski <bmarzins@redhat.com> --- libmultipath/discovery.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)
