Clustering filesystems

SunOS 5.10 Generic_142900-15 sun4u sparc SUNW,SPARC-Enterprise

How can I tell if "clustering" is being used in my shop?
I have to file systems that are identical. These filesystems are nfs mounted. But how can I tell if they are being kept in sync as a result of clustering or some other method?

/CV /CV nfs nodevices,bg,intr,xattr,zone=cbp011,dev=5500011 1288539528

/eabatch/EABATCH /EABATCH nfs nodevices,bg,intr,xattr,zone=cbp011,dev=5500010 1288539528

Please post your /etc/vfstab file.

One thing that's interesting from the output above, which I assume is from your /etc/mnttab file, is that normally NFS filesystems usually appear in the format of

host:/path/to/share /path/to/mountpoint nfs options

but there is no 'host:'. That could mean that some sort of clustered NFS solution is being used, such as HP ServiceGuard, or it could mean something else.

Where and how is this being mounted? Is it located in /etc/vfstab, or is it being mounted by some rc script at boot time, or ...? To check the rc scripts at boot, do something like:
find /etc/rc?.d -exec grep "mount" \{\} \;
