Trying to Extend LV's in a VG getting error

[marvin51796]

Can someone tell me how to fix this error?? I am trying to do a lvextend in SMH and this is what i am getting. I have never seen this before and we do not have /etc/lvmpvg file.

thanks

actually i have this working now, apparently when you have snap's that are mounted for backups it creates problems with LVM if you are trying to do LV expands..

thanks anyway
