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 <a href="http://10.100.1.170:7789">10.100.1.170:7789</a>; meta-disk internal; } on wahoo2 { device /dev/drbd0; disk /dev/sda2; address <a href="http://10.100.1.171:7789">10.100.1.171:7789</a>; meta-disk internal; } } ------------------------- Any ideas? thanks, rotseN
