Note: "permalinks" may not be as permanent as we would like,
direct links of old sources may well be a few messages off.


at the moment I'm trying two different DRBD setups:

1. RAID -> LVM -> DRBD -> NFS
2. RAID -> DRBD -> LVM -> NFS

I always use "meta-disk internal;" as DRBD config. Looking at DRBD
http://www.drbd.org/users-guide/ch-internals.html#s-internal-meta-data I
have to resize the lower-level LVM volume, "as long as you have free space
available in the corresponding volume group or container". According to the
documentation this would mean setup 1. Other sources in the web say it is
the other way round (setup 2 has to be resized). I also think so.

Can anyone give some information in which scenario resize is really

Thanks for every reply.

Best wishes
