Sounds to me like something is on its way out.
Sounds like good advice even when there's nothing suspeicious going on. The work I can't afford to lose is, in any case, duplicated on another system using a distributed revision management system (monotone). -- hendrik > > The fact that you upgraded just prior to this symptom's appearance > casts an accusing finger at the upgrade, and that certainly should be > investigated.

That doesn't seem to be the click problem, because /proc/mdstat reports all my RAID drives to be OK. Wiggling wires sounds like something to do *after* that thorough backup. One nice thing about rdiff-backup is that if it backs up a corrupt file, it's still possible to find the previous versions. -- hendrik > > I had an intermittent click several years ago that turned out to be a > defective hard disk power connector. > > SteveT > > Steve Litt > June 2018 featured book: Twenty Eight Tales of Troubleshooting > http://www.troubleshooters.com/28 > > > _______________________________________________ > Dng mailing list > [email protected] > https://mailinglists.dyne.org/cgi-bin/mailman/listinfo/dng _______________________________________________ Dng mailing list [email protected] https://mailinglists.dyne.org/cgi-bin/mailman/listinfo/dng
