fence_devices {
gnbdmp {
agent = "fence_gnbd"
server = "nodea"
server = "nodeb"
option = "multipath" <--
Additional entry
retrys = "5" <--
Number of retries set to 5
wait_time = "3" <--
Wait time between retries set to 3
}
}
This example shows a fencing device named
gnbdmp
with two servers:
nodea
and
nodeb
. Because
GNBD Multipath is employed, an additional configuration entry under gnbdmp is needed:
option =
"multipath"
. Also, for GNBD multipath, the example sets the number of retries to 5 with
retrys
= 5
, and sets the wait time between retries to 3 with
wait_time = 3
.
Example 6-8. GNBD Fencing Device Named
gnbdmp
, with GNBD Multipath
fence_devices {
riloe1 {
agent = "fence_rib"
ipaddr = "10.0.4.1"
login = "admin"
passwd = "password"
}
riloe2 {
agent = "fence_rib"
ipaddr = "10.0.4.2"
login = "admin"
passwd = "password"
}
}
In this example, two RILOE fencing devices are defined for two nodes.
