Hi List!
I'm going to stick Solaris 10 on my laptop (this is not an advocacy
post, just for info) and to do so I need to free up some physical space
on my disk which is currently allocated to LVM2.
I'm thinking that the steps below are what I need to do to get where I
want to be, but would appreciate any comments or pointers from the list
about things I may have missed, gotchas and the like.
I have:
/dev/hda1 * 1 13 104391 83 Linux
/dev/hda2 14 4864 38965657+ 8e Linux LVM
where the VG is:
VG Name VolGroup00
[snip]
VG Size 37.16 GB
and LVs are:
LV Name /dev/VolGroup00/LogVol00
VG Name VolGroup00
[snip]
LV Size 36.62 GB
[snip]
--- Logical volume ---
LV Name /dev/VolGroup00/LogVol01
VG Name VolGroup00
[snip]
LV Size 512.00 MB
[snip]
It's a standard install. That's root and swap.
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/mapper/VolGroup00-LogVol00
37801496 19290132 16591160 54% /
Filename Type Size Used
Priority
/dev/mapper/VolGroup00-LogVol01 partition 524280 57888 -1
So all my physical space is used up by volumes, but there is free space
on the filesystem. I want about 10Gb of physical free space that I can
create a Solaris partition in. The plan is:
0) back everything up ;-)
1) boot from the rescue CD, unmount/fsck filesystems
2) resize2fs "/" down by 11Gb
3) lvreduce the root volume down by 10Gb
4) resize2fs "/" back up to fill the LV
5) with fdisk, delete the partition entry and recreate from same
starting block, but ending the partition ~10Gb short of where it ends now.
6) reboot and pray.
7) with fdisk, create a space for Solaris to live, and install.
I have a bad feeling about step 5, but I can't see another way to do
this, given there's no "pvresize".
Any comments would be *really* useful!
Thanks in advance.
Craig.
