[linux-lvm] Large disk problem with LVM2...

[Greg Varga]

I have a 3.09TB Hardware Raid 5 drive setup with, and I have already
used about 1TB worth of space on the volume group.

Today I tried to add another 500GB logical volume and it failed with:

[root at bill ~]# lvcreate -L500G -ntest VolGroup01
  device-mapper: reload ioctl failed: Invalid argument
  Aborting. Failed to activate new LV to wipe the start of it.


dmesg shows this:

device-mapper: table: device 8:3 too small for target
device-mapper: table: 253:7: linear: dm-linear: Device lookup failed
device-mapper: ioctl: error adding target to table


I have googled for the message and have read to run pvs like:

[root at bill ~]# pvs -o +dev_size
  PV         VG         Fmt  Attr PSize  PFree DevSize
  /dev/sda2  VolGroup00 lvm2 a-   99.97G    0  100.00G
  /dev/sda3  VolGroup01 lvm2 a-    3.09T 2.05T   1.09T


So my question is, how do I fix this?  I'm running the most current
(CentOS 5.2) versions of Device-Mapper and LVM and Kernel:

lvm2-2.02.32-4.el5_2.1
lvm2-cluster-2.02.32-4.el5
device-mapper-1.02.24-1.el5
device-mapper-event-1.02.24-1.el5
device-mapper-multipath-0.4.7-17.el5
kernel-2.6.18-92.1.18.el5

Anyone have any ideas why pvs shows the DevSize of 1.09TB?
