I might be doing something wrong, because you say "you are fine" but didn't
work :(
All servers have "/opt/app" mounted in same internal disk partition.
They are not shared, it is just that all have identical layout.
I tried to create:
Resource name: Central_FS
Device: /dev/mapper/VolGroup00-optvol
FS Type: ext3
Mount point: /opt
And
Resource name: Collector_FS
Device: /dev/mapper/VolGroup00-optvol
FS Type: ext3
Mount point: /opt
When I tried to save it I found in the /var/log/messages:
clurgmgrd[4174]: <notice> Reconfiguring
clurgmgrd[4174]: <err> Unique attribute collision. type=fs attr=mountpoint
value=/opt
clurgmgrd[4174]: <err> Error storing fs resource
Thanks for your help and ideas!
