(resending, first try didn't seem to make it to the archives)
Due to dracut creating huge initrds, I now need a larger /boot. So I'd
like to reduce my lvm physical volume on the same disk in order to make
room.
However, lvm doesn't want me to:
lvm> pvs
PV VG Fmt Attr PSize PFree
/dev/sda2 vg0 lvm2 a- 148.94G 10.00G
Seems I have enough room.
lvm> pvresize --setphysicalvolumesize 148.54G /dev/sda2
/dev/sda2: cannot resize to 4753 extents as later ones are allocated.
0 physical volume(s) resized / 1 physical volume(s) not resized
So it seems lvm wants me to move the data around instead of doing it by
itself. What did I do (besides not reading the manual)?
Let's find a new home for the data:
[root@violet-regb ~]# pvs --segments
PV VG Fmt Attr PSize PFree Start SSize
/dev/sda2 vg0 lvm2 a- 148.94G 10.00G 0 480
/dev/sda2 vg0 lvm2 a- 148.94G 10.00G 480 192
/dev/sda2 vg0 lvm2 a- 148.94G 10.00G 672 320
/dev/sda2 vg0 lvm2 a- 148.94G 10.00G 992 320
/dev/sda2 vg0 lvm2 a- 148.94G 10.00G 1312 320
/dev/sda2 vg0 lvm2 a- 148.94G 10.00G 1632 2560
/dev/sda2 vg0 lvm2 a- 148.94G 10.00G 4192 128
/dev/sda2 vg0 lvm2 a- 148.94G 10.00G 4320 64
/dev/sda2 vg0 lvm2 a- 148.94G 10.00G 4384 320
/dev/sda2 vg0 lvm2 a- 148.94G 10.00G 4704 62
Looks like all extents are already allocated (that's the 'a', right?).
But it claims that 10G are free! And sure, if I create a new volume,
space is found at extent 4384:
[root@violet-regb ~]# lvcreate -L 1G -n new vg0
Logical volume "new" created
[root@violet-regb ~]# pvs --segments
PV VG Fmt Attr PSize PFree Start SSize
/dev/sda2 vg0 lvm2 a- 148.94G 9.00G 0 480
/dev/sda2 vg0 lvm2 a- 148.94G 9.00G 480 192
/dev/sda2 vg0 lvm2 a- 148.94G 9.00G 672 320
/dev/sda2 vg0 lvm2 a- 148.94G 9.00G 992 320
/dev/sda2 vg0 lvm2 a- 148.94G 9.00G 1312 320
/dev/sda2 vg0 lvm2 a- 148.94G 9.00G 1632 2560
/dev/sda2 vg0 lvm2 a- 148.94G 9.00G 4192 128
/dev/sda2 vg0 lvm2 a- 148.94G 9.00G 4320 64
/dev/sda2 vg0 lvm2 a- 148.94G 9.00G 4384 32
/dev/sda2 vg0 lvm2 a- 148.94G 9.00G 4416 288
/dev/sda2 vg0 lvm2 a- 148.94G 9.00G 4704 62
32 extents, 32MB each = 1GB. Let's move the 62 extents at the end manually:
[root@violet-regb ~]# lvremove vg0/new
Do you really want to remove active logical volume new? [y/n]: y
Logical volume "new" successfully removed
[root@violet-regb ~]# pvmove /dev/sda2:4704-4765 /dev/sda2:4384-4445
No extents available for allocation
At this point I gave up. Is there any way to accomplish this?
