[dm-devel] lvresize fails with "reload ioctl failed: Invalid argument"

[Laurent Riffard]

Hello,

I'm unable to resize any LV, it fails with such a message:

[root at calimero ~]# lvresize --extents +1 /dev/vglinux1/lvswap2
  Extending logical volume lvswap2 to 1.00 GB
  device-mapper: reload ioctl failed: Invalid argument
  Failed to suspend lvswap2

[root at calimero ~]# lvm2 version
  LVM version:     2.02.06 (2006-05-12)
  Library version: 1.02.09 (2006-08-15)
  Driver version:  4.8.0
[root at calimero ~]# cat /proc/version 
Linux version 2.6.18-rc6-mm1 (laurent at calimero.antadix) (gcc version 4.1.1 20060724 (prerelease) (4.1.1-3mdk)) #145 Sun Sep 10 20:48:49 CEST 2006

Is it a known problem ? 


I can't tell precisely when it started to fails. This failure
appeared when I udpated my distro from Mandriva 2006.0 to 2007.0
beta. So I guess I was working with lvm 2.01.09 and libdevmapper
1.01.00. 

Here is some additional info on my environment:
