Hi everybody,
I'm trying to test heartbeat with drbd in a cluster.
My network is :
_____________ SW _____________
| Heartbeat link |
| |
|eth0 | eth0
___|___ ___|___
| | | |
| SRV 1 | | SRV 2 |
|_______ | |_______|
First time, I only used one ethernet card on each server.
Everythings work ok i have been tested all the possible options of failure, but
when I disconnected network cables from node 1, I noticed that node 2 became active. But when I restored network connections for node 1, it failed to be backup "split brain".
resource drbd0 {
protocol C;
handlers {
pri-on-incon-degr "echo 'DRBD: primary requested but inconsi! |wall; /etc/init.d/heartbeat stop"; # "halt -f";
pri-lost-after-sb "echo 'DRBD: primary requested but lost! |wall; /etc/init.d/heartbeat stop"; #"halt -f";
local-io-error "echo o > /proc/sysrq-trigger ; halt -f";
}
startup {
degr-wfc-timeout 120; # 2 minutes.
}
disk {
on-io-error detach;
}
net {
cram-hmac-alg "sha1";
shared-secret "secret";
}
syncer {
rate 10M;
al-extents 257;
}
on main {
device /dev/drbd0;
disk /dev/mapper/VolGroup00-home;
address 192.168.1.66:7788;
flexible-meta-disk internal;
}
on backup {
device /dev/drbd0;
disk /dev/mapper/VolGroup00-home;
address 192.168.1.65:7788;
meta-disk internal;
}
}
after a slit brain situation i got like this
#cat /proc/drbd
main:
0: cs:StandAlone st:Primary/Unknown ld:Consistent
ns:8 nr:0 dw:380 dr:50 al:1 bm:49 lo:0 pe:0 ua:0 ap:0
backup:
0: cs:StandAlone st:Secondary/Unknown ld:Inconsistent
ns:0 nr:8 dw:16 dr:17 al:1 bm:293 lo:0 pe:0 ua:0 ap:0
Does anybody knows how can i resolve this issue in order to to synchronize the data and to reestablish the service?
Because after handlers i wrote:
pri-on-incon-degr "echo 'DRBD: primary requested but inconsi! |wall; /etc/init.d/heartbeat stop"; # "halt -f";
pri-lost-after-sb "echo 'DRBD: primary requested but lost! |wall; /etc/init.d/heartbeat stop"; #"halt -f";
local-io-error "echo o > /proc/sysrq-trigger ; halt -f";
but it doesn't works
regards
thanks
