We had a massive power failure, beyond what the UPS could handle.
Despite attempts to find a way for the system to shut down gracefully,
it simply powered down without unmounting the disk partitions.
Nominally, the backup local UPS I am using (APC Back-UPS 650) has an
interface Port DB-9 RS-232 but I have not found any Linux application
that reliably would communicate with this model of UPS (that is, emulate
the same behavior as the application available from APC for MS Win that
senses the RS-232 information from APC, waits the appropriate time, and
then shutdown -- anyone found one?).
apcupsd, available from rpmforge?
Works fine on my ancient APC Back-UPS Pro device using the supplied
940-0024C cable. You do need the right cable though, and must configure
it accordingly.
Check your cable type and UPS compatibility here:
