[dm-devel] Problem with creating LV - device too small for target



Hello

We have experienced problem with creating very big LV. During creating
we get:

device-mapper: reload ioctl failed: Invalid argument
Failed to activate new LV.

and in dmesg:

device-mapper: table: device 8:16 too small for target
device-mapper: table: 253:25: linear: dm-linear: Device lookup failed
device-mapper: ioctl: error adding target to table

Our structure looks:

So it looks like we should have 113581 PE free but during creating LV:

lvcreate -l 112000 vg+vg00 -n lv0004

we get Invalid argument.

Verbose shows that lvcreate tries to reserve a few free segment but
without success:

Kernel 2.6.27.39 and LVM:

   LVM version:     2.02.33 (2008-01-31)
   Library version: 1.02.24 (2007-12-20)
   Driver version:  4.14.0

We have tried to use the newest version of LVM

  LVM version:     2.02.76(2) (2010-11-08)
  Library version: 1.02.57 (2010-11-08)
  Driver version:  4.15.0


but effect was the same.

Maybe you know where the problem is? We are not able to change the
kernel version.

Thanks in advance.
