I am getting this errors when running the command "drbdadm adjust mysql" on
WAHOO:
Failure: (114) Lower device is already claimed. This usually means it is
mounted.
Command 'drbdsetup /dev/drbd0 disk /dev/sda2 /dev/sda2 internal
--set-defaults --create-device --on-io-error=detach' terminated with exit
code 10
And on my second node WAHOO2, I get:
No response from the DRBD driver! Is the module loaded?
Command 'drbdsetup /dev/drbd0 disk /dev/sda2 /dev/sda2 internal
--set-defaults --create-device --on-io-error=detach' terminated with exit
code 20
This is what my /etc/drbd.conf file looks like:
resource mysql
{
protocol C;
# incon-degr-cmd "echo '!DRBD! pri on incon-degr' | wall ; sleep 60 ; halt
-f";
startup { wfc-timeout 0; degr-wfc-timeout 120; }
disk { on-io-error detach; } # or panic, ...
syncer {
rate 6M;
}
on wahoo {
device /dev/drbd0;
disk /dev/sda2;
address 10.100.1.170:7789;
meta-disk internal;
}
on wahoo2 {
device /dev/drbd0;
disk /dev/sda2;
address 10.100.1.171:7789;
meta-disk internal;
}
}
-------------------------
Any ideas?
thanks,
