i finally managed to get my system moved over to lvm2 so i won't ever have to manually move, grow, shrink, etc. partitions ever again.
however, my paritition is 120 GB:
Name Flags Part Type FS Type [Label] Size (MB)
------------------------------------------------------------------------------
sda1 Boot Primary Linux ext3 131.61
sda2 Primary Linux LVM 122885.69
and yet the volume group only has 114 GB available:
--- Volume group ---
VG Name lvg1
System ID
Format lvm2
Metadata Areas 1
Metadata Sequence No 6
VG Access read/write
VG Status resizable
MAX LV 0
Cur LV 5
Open LV 4
Max PV 0
Cur PV 1
Act PV 1
VG Size 114.44 GB
PE Size 4.00 MB
Total PE 29297
Alloc PE / Size 17408 / 68.00 GB
Free PE / Size 11889 / 46.44 GB
VG UUID blargh-blah-foob-arrr-stuff-junk-blargh
what gives? where'd those 6 gigs go?

Could this be another GiB vs GB conversion issue? I don't think the numbers look right for that, as 122885/1024 = 120 and not 114. Strange. Not as strange as whatever the hell that thing is in your avatar, but strange.

hmmm...
114.4 * 1024 * 1024 * 1024 = 122836064665.6 Bytes
122885.69 * 1024 * 1024 = 128854985277.44 Bytes
128854985277.44 - 122836064665.6 = 6018920611.84 Bytes difference
6018920611.84 / 1024 / 1024 / 1024 = 5.605556640625 GB difference
i know hardware manufacturers' marketing departments take advantage of the GiB/GB difference, but i'm going to hazard a guess that the authors of lvm2 and cfdisk don't.
i also know that partition tables, block-device encryption, and logical-volume management all entail some disk-space overhead, but
5.605556640625 / ( 122885.69 / 1024 ) = ~4.67108 %
5%. does that seem suspicious? i really don't know.
p.s.: that thing is a holoprosencephallic piglet. it's not my usual avatar, but i couldn't find that file after the harddrive switch. i like it 'cuz it's hideous and adorable all at once, kind of like a good kludge.

I suppose it's too late to care about this, but it is said in the wiki that ext3 reserves 5% of space for "special reasons". See http://wiki.archlinux.org/index.php/Ext … stem_Space
