Hello,
I am new to drbd, and I am just getting this set up. I am having a few
problems. I am running 8.3 now on CentOS 5.3 64bit version. All latest
patches applied.
I am getting errors, see way below.. I am just at the initial sync
step.
nas1 is configured with:
6 x 1TB & 2 x 250 drives, 8gb ram, adaptec 5805 raid card RAID 5 on
the 6 drives
nas2 is configured with
4 x 1.5TB & 2 x 250 drives, 8gb ram, adaptec 5805 raid card RAID 5
on the 4 drives
/data partition is /dev/sdb1 which is a total of 4,200,000 MB (about
4TB)
/meta partition is /dev/sdb2
configuration: /etc/drbd.conf
uname -a:

When first starting up, it starts syncing for about 10-15 minutes...
(you can see it's down to 3,513,200 left to sync)...

As soon as that starts, then we get all kinds of errors like this

At this point, ssh is extremely sluggish on nas2.. to the point it
takes 30-60 seconds to type anything...
and you'll see it's no longer syncing

My only thought is that the switch between the 2 machines is bad, but
why would that lockup the machine...?
thanks
Marc
