fence_devices {
gnbd {
agent = "fence_gnbd"
server = "nodea"
server = "nodeb"
}
}
This example shows a fencing device named
gnbd
with two servers:
nodea
and
nodeb
.
Example 6-7. GNBD Fencing Device Named
gnbd
, without GNBD Multipath
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 {
notify_gnbd {
agent = "fence_notify_gnbd"
client = "10.0.1.1"
client = "10.0.1.2"
client = "10.0.1.3"
}
}
