[linux-lvm] mirror error

[Daniele Palumbo]

hi.

i have a problem, found also online without resolution.

i have compiled lvm2 2.0.22 without mirror (--with-mirror=none), but  
for every lv command i have an error:
"Unrecognised segment type mirror"

now look at that:
--
backuphost ~ # vgchange -cy XenBackupVolume
   Unrecognised segment type mirror
   Unrecognised segment type mirror
   Volume group "XenBackupVolume" is already clustered
backuphost ~ # lv
-bash: lv: command not found
backuphost ~ # lvs
   Unrecognised segment type mirror
   Unrecognised segment type mirror

   gentoo-mirror XenBackupVolume -wi-a- 100.00G
   prova         XenBackupVolume -wi-a-   4.00G
