My only "advice" is to try and quantify the data volume and look at
nbd vs. iSCSI to provide the mirror if you go that way.
You mentioned nbd as a transport for disk to remote disk .
My Question is have you OR anyone else tried using drbd(*) as a
method to replicate disk data across networks ?
Have not. And looking at the homepage, I think it's aimed at anothjer
problem. If the local drive fails, I really don't want anything starting
applications on another machine, running fsck, etc, etc. I just want my
disk reads to go to a working device or pseudo-device.
HA and mirroring are related, but HA is more aimed at whole machine
failures.
I've looked at the projects documents & software . They're
mentioned at linux-ha . But I personally have not heard of anyone
using it in production . So I asked my question here .
