hi,
problem:
I want to merge 2 partitions into one partition,
as 80g part 1 has run out of space. It has OS and
most space used is /home occupying about 66 g.
CentOS 6.4 or 5, 2 gig ram ( runs pretty good for single core )
HD = 160g drive ( serial onboard IF )
HD = (part 1 = 80 gig ext4 )+ (part 2 /swap 4 (?) gig) + (part 3 = 80 gig)
(fdisk data below)
***for the avid reader:
part 1 contains OS + /boot + /home ( all except swap )
part 3 empty. Will simply remove /swap until done.
# mount
/dev/sda1 on / type ext4 (rw)
desire a little discussion, but no longer desire to be
a partitioning expert. In particular,
looks like I need to remove swap. this is easy.
To extend, it looks like cylinder total is 19457,
I'd use 10200 to ~18948 ? )
then remake swap at 18949 ( hopefully software just lets me
select num of gigs ).
1. grow part 1 into part 2 and 3?
( probably boot from live CD, fedora 12, or 16 or something
similar most likely. )
2. utility to use ?
3. effect of LVM being turned on ? )
I've never "used" a LVM other than selecting ON/OFF
from install menu.
4. effect of selinux in permissive mode.
5. any other config's/options to think about ?
6. The complicated way ( for me ) would be to partition
the empty 80 gig, mkfs ext4 and use LVM to add it to
part 1. generally, I don't want to think about this..
( but a little/short info about it may be handy )
7. I have a 32 gig flash drive. I suppose I could move
the whole OS except home to this first ? I can backup
/home to a spare 80 gig ide drive I have here..
