Bug#306200: lvm2: please use SI units

[Benoît Dejean]

Package: lvm2
Version: 2.01.04-3
Severity: important

The lvresize manpages says:

"A size suffix of M for megabytes, G for gigabytes or T for terabytes is optional."

it's unclear if M, G, T mean

a) 2^20B, 2^30B, 2^40B 
b) 10^6B, 10^9B, 10^12B

if (a), then the manpage should use SI units MiB, GiB and TiB.

lvdisplay --units is undocumented
 [--units hsbkmgtHKMGT] ? what are these units ? Does M stand for MB or MiB ?


The BIPM brochure says:

"These SI prefixes refer strictly to powers of 10. They should not be used to
indicate powers of 2 (for example, one kilobit represents 1000 bits and not 1024
bits)"

Please consider using [KMG]iB instead of [kMG]B
