Hi,
I have an lvm root, which I am trying to expand into pv free space:
=====pvs -v
Scanning for physical volume names
PV VG Fmt Attr PSize PFree DevSize PV UUID
/dev/sda2 vg2 lvm2 a- 49.28G 0 49.29G

/dev/sda3 vg2 lvm2 a- 49.28G 0 49.29G
o8fVEA-PilV-Pwum-WDtH-O2lF-XOTW-2XPeWu
/dev/sda4 vg2 lvm2 a- 49.28G 0 49.29G

/dev/sdd3 vg2 lvm2 a- 13.86G 0 13.87G
n1kZD5-VCP2-Erj1-rtSg-3kki-5Iod-DyAmNG
so: 13GB free on vg1...
=====lvs -v

8q5eTn-6ruu-NS5E-Zf6o-e88H-Urae-gXdB2Y
and lvslash is on vg1 and I want to grow it by +4GB
=====
- boot rescue
- don't mount
- lvm vgchange -a y
- lvm lvextend -v -L+4G /dev/vg1/lvslash
Trying to remember the error:
=====
...
Loading vg1 table
device-mapper: reload ioctl failed: invalid argument
Failed to suspend lvslash
=====
Now I only looked at pvs since alastair suggested another user with a
similar problem.
In fact, while pvs says vg1 has 13.88G free, I think this is actually
really supposed to be a negative number, since:
(DevSize) - (PSize) = (PFree)
34.59G - 48.41G = -13.82 /= 13.88
, which looks like a bug in at least pvs !
I don't know how I got into this situation, nor how to proceed, but do
know that the access to all the disk partitions is working normally at
he moment, despite the above inconsistency.
Any ideas on how to solve this ?
