Reliability of (Sys V) file systems on power failure

[LCDR Michael E. Dobson]

My system, an AT&T 3B2/600G running AT&T Sys V R 3.2.2 supposedly has a hardened
file system, however, I have had to restore from a boot floppy and tape on
occaision after a power failure.  Because of this, in addition to an UPS, I
have installed a powerfailure monitor which automaticly begins the shutdown
sequence when it senses a powerfailure from the primary power source.  The
UPS provides sufficient time for users to log off and for the sutdown sequnce to
complete.  For a cost of ~$250 for the transducer/software, it's a very good
investment.  E-mail if you want details on the product.
