Thanks for your feedback. I finally checked the RA script and found the
error

in clvm2 RA script on non working nodes I got
# Common variables
DAEMON="${sbindir}/clvmd"
CMIRRORD="${sbindir}/cmirrord"
LVMCONF="${sbindir}/lvmconf"

on working node
DAEMON="/usr/sbin/clvmd"
CMIRRORD="/usr/sbin/cmirrord"

Looks like it was path variables were not interpreted. I just have to
check why I did get those versions

THanks again for your answer
