# Short-Description: Start and stop the MD multipath monitor |
15 |
# Description: The mdmpd service checks the status of all MD based multipath |
16 |
# devices on the system. If a path to a device goes down, it removes |
17 |
# that path from the md multipath array. It also periodically attempts |
18 |
# to contact the device via the down path. When it succeeds repeatedly, |
19 |
# it re-adds the downed path to the multipath array. There is a roughly |
20 |
# 60 second delay between when a path becomes live again and when mdmpd |
21 |
# adds it back into service. |
