Thank you.  We had been using multiple read-only UFS monts and one R/W mount as a \
"poor-man's" technique to move data between SAN-connected hosts.  Based on your \
discussion, this appears to be a Really Bad Idea[tm].

That said, is there a "HOWTO" anywhere on installing QFS on Solaris 9 (Sparc64) \
machines?  Is that even possible?
