Hello again!
I've followed the instructions below (based on an earlier post from
Michael Hoennig), and everything went ok.
Now for the test:
# dd if=/dev/zero of=/tmp/drbd_0/zero count=10
1. Nothing arrives at /tmp/drbd_1/
Does anyone confirms if this works?
2. It seems that drbd_1 is mounted read-only. I need it to be RW.
Is it possible?
3. # drbdsetup /dev/nb0 replicate
"replicate is not a command"
What? :)
This is the output for 'cat /proc/drbd' after a few tries:
version: 0.7-pre6 (api:72/proto:72)
0: cs:Connected st:Primary/Secondary ld:Consistent
ns:8292 nr:0 dw:0 dr:8192 al:2 bm:2 lo:0 pe:0 ua:0
1: cs:Connected st:Secondary/Primary ld:Consistent
ns:0 nr:8292 dw:8292 dr:0 al:0 bm:2 lo:0 pe:0 ua:0

Just wondering, this file would have an equivalent in the secondary
node, right?
Doesn't it get screwed up by using loopbacks?
The documentation is pretty outdated, I'll try to help here whenever
I understand a bit of what it's going on here. Have you ever
considered installing a wiki?

This is what I've done:
