too small for target
There's your answer: You're trying to make it bigger than the underlying
device.

Use pvs -v to check device sizes for discrepancies.
(--units s if necessary).

Thanks, now I can see what the problem is:

[root fc11-64 ~]# pvs -v
    Scanning for physical volume names
  PV         VG         Fmt  Attr PSize  PFree  DevSize PV UUID
  /dev/sda2  vg_fc1164  lvm2 a-   99.80G     0   99.80G
qunnek-OG2y-hp2j-31J8- J3HT-0Aye-3w2rMN

eCuGyH-jV7L-Tgdg-JyYW- sWK1-ehZY-OLw0WS


How is this possible?
What's the solution?
How can I grow the DevSize?
Probably a better question to ask is, how can I add the unused space into
the device and then the volume?
Hi Hugh,

taking into account this:
Maybe I should provide some more background.
I have a vmware virtual disk and I have grown the disk size by 20G.
and...

[root fc11-64 ~]# parted -l

you have to resize sdb2 partition first.

Though I do not understand why it is possible to resize PV beyond end of
device (doing that should display a warning message, but command will
pass), this is definitely not a LVM bug.

HTH,

Thank Marian,

Any idea how to resize sdb2?
Easy. Just search web for:
   linux resize partition

Or check these direct links:
   command line GNU parted: http://www.gnu.org/software/parted/index.shtml
   GNOME gparted: http://gparted.sourceforge.net/
   KDE qtparted: ...
It's lvm and maybe I could delete it and recreate it with fdisk but maybe it will break and everything will be lost.
Marian
