Hi,
I have a system with 2.73 TB partition on witch a VG group was created:
# pvdisplay
--- Physical volume ---
PV Name /dev/sdc1
VG Name storage0
PV Size 2.73 TB / not usable 2.00 TB
Allocatable yes
PE Size (KByte) 65536
Total PE 44701
Free PE 32803
Allocated PE 11898
PV UUID n1wiZE-PmlM-sAaH-I8cl-ORUZ-GReQ-54xlf7
Notice that it says that 2 TB is not usable, which according to
https://www.redhat.com/archives/linux-lvm/2005-August/msg00033.html
is a sign of lvm tools is not able to handle devices this large.
After upgrading lvm tools the pvdisplay says that all the space is
usable. However creating LVs that total in size over 0.73 TB (2.73 - 2)
is not possible and fails with following error messages:
# lvcreate -L 65g -n export storage0
device-mapper ioctl cmd 9 failed: Invalid argument
Couldn't load device 'storage0-export'.
Failed to activate new LV.
following errors are logged in /var/log/messages:
Oct 2 17:48:35 sinclair kernel: device-mapper: device /dev/sdc1 too
small for target
Oct 2 17:48:35 sinclair kernel: device-mapper: dm-linear: Device lookup
failed
Oct 2 17:48:35 sinclair kernel: device-mapper: error adding target to table
Anyone knows what's going on ? How can i reclaim this 2TB of storage ?
Here follows some version details:
The VG was originaly created with following tools:
# lvm version
LVM version: 2.00.31 (2004-12-12)
Library version: 1.00.19-ioctl (2004-07-03)
Driver version: 4.1.0
Since then the tools have been upgraded to following versions:
# lvm version
LVM version: 2.01.08 (2005-03-22)
Library version: 1.01.01 (2005-03-29)
Driver version: 4.4.0
The upgraded pvdisplay then says:
# pvdisplay
--- Physical volume ---
PV Name /dev/sdc1
VG Name storage0
PV Size 2.73 TB / not usable 0
Allocatable yes
PE Size (KByte) 65536
Total PE 44701
Free PE 32803
Allocated PE 11898
PV UUID n1wiZE-PmlM-sAaH-I8cl-ORUZ-GReQ-54xlf7
T.i.a,
