RE: [Linux-cluster] quickie GFS with lock_nolock question



Title: [Linux-cluster] quickie GFS with lock_nolock question
For example, in /etc/fstab an entry could look like:
 
/dev/VGCCC/lvolshare    /cluster/share          gfs     lockproto=lock_nolock  0 0
An ad-hoc mount could look like:
 
mount -t gfs -o lockproto=lock_nolock /dev/VGCCC/lvolshare /cluster/share
Make certain that this filesystem is not mounted anywhere else before overriding, because it will corrupt.

Subject: [Linux-cluster] quickie GFS with lock_nolock question

we have a funky custom application that doesnt seem to like
reading/writing to the shared GFS filesystem we have on our 2node
cluster. someone at the vendor suggested just having the main node mount
the GFS filesystem with "lock_nolock" to see if that would fix the problem.
What is the correct way to go through the motions to do this? because
currently they both mount up the gfs partition and I believe its a
dependency for the other services. feel free to direct me to the right
FM to RTFM.
