direct links of old sources may well be a few messages off.

Hi all,

I'm a bit new in the field. To resize partitions, is it enough to have
the same number of MB as reported by gParted? Or is there something
special I must do to have the exact same size?

In particular, I am worried that, my disks on several nodes being of
different brands and models, having the same size in MB would not be
sufficiently similar to let DRBD accept them... What's the rule to "have
them the same size" and how would it be best done on Linux Debian-based
systems?

I haven't read much of the doc yet so feel free to RTFM me to the right
section.

Thx,

Yannick
