I installed drbd with hearbeat on two machine. Since both of the machines are in a production environment, rebooting the machines can be quite a task. I set up DRBD on one machine with a an flexible-internal metadata disk. The other machine had DRBD setup with a external metadata disk. Since the data we need to replicate already exists on a disk, we need to go with an external metadata disk. This is the configuration on both machines.
on apophis {
device /dev/drbd0;
disk /dev/mapper/mars-tmp;
address 199.131.563.91:7789;
flexible-meta-disk /dev/mapper/mars-boot;
}
on mars {
device /dev/drbd0;
disk /dev/cciss/c0d0p7;
address 199.131.563.90:7789;
flexible-meta-disk internal;
}
I began by zeroing out the disks for metadata with
dd if=/dev/zero of=/dev/mapper/mars-boot bs=1M count=128
dd if=/dev/zero of=/dev/cciss/c0d0p7 bs=1M count=128
I created metadata disks on both machines with the command
drbdadm create-md home
Then tried to start DRBD with the System V init script
/etc/init.d/drbd start
DRBD started on mars, but when I tried to start it on apophis I got this
message
Low.dev. smaller than requested DRBD-dev. size.
/dev/mapper/mars-tmp is 4TB
/dev/mapper/mars-boot is 9.9GB
/dev/cciss/c0d0p7 is 7 TB
mars is running
version: 8.0.14 (api:86/proto:86)
Linux 2.6.26-2-amd64
apophis is running
version: 8.3.7 (api:88/proto:86-91)
Linux 2.6.32-5-amd64
Any ideas here?
