Ok. Type "ifconfig".

node1 must be one of the IP addresses listed by ifconfig/ip addr show.

Hi,

ok - I forwent the drbdsetup route and used the /etc/drbd.conf route - THIS
seems to work and I have the "mirror" up and /dev/nb0 mounted on both node1
and node2.

Question : It mounts /dev/nb0 as READ-ONLY on node2 - is this correct ???

Many Thanks for all you help and patience :)

Yes. You can only have one node writing to the device and any given time, and
very likely you are going to shot yourself in the foot royally if you mount it
r/o on the secondary too.

Hi,

thanks for the reply :)

ok - so I understand that part - no for the difficult question ....

Say the Primary server (node1) dies and I need to use the secondary - what
is the procedure for mounting the /dev/nb0 on secondary and then using it
???

Thanks again :)

lowlevel:

drbdsetup /dev/nb0 primary
fsck /dev/nb0
mount /dev/nb0 ...

highlevel:

/etc/ha.d/resource.d/datadisk drbd0 start
