ufs without logging is the only safe option for the inode fileserver on 
solaris.

The default logging option was changed in Solaris 9 9/04
See http://docs.sun.com/app/docs/doc/817-5770/6ml72d6kd?a=view

It's sneaky because the default is logging is on for disks over 100G or 
some similar threshold.

UFS with logging WILL eat data with the inode server, you will have to 
salvage on each service restart when the /vicepX is unmounted and 
remounted (i.e. every boot/reboot).

The namei fileserver is safe for ufs (with or without logging) and ZFS 
filesystems on solaris.

Use namei, it's safer and faster on ufs w/logging than inode without 
logging.

BTW, where should I document tidbits like this?
