Well, my poor hot-rodded Cobalt Qube 2 finally blew a gasket.
I shouldn't be too surprised -- I'd upgraded from 32MB of RAM
to 128MB, from 6GB of disk to 64GB, and added a wireless PCI
card to make it into a host access point. All that *had*
to have some impact.
The problems started a few days ago, when I woke up to find
the box unresponsive. I checked the serial console, and it
continuously complained about errors writing to disk.
When I turned it off and then on again, it failed to read
the kernel from the boot disk.
I had visions of losing my (un-backed-up!) mail and digital
pictures, but then I found that the disk worked on my i386
box. Argh! And the Qube would boot off of the original
I tried some more experiments, to see if the boot image on
the 64GB disk was bad. I found that the Qube would power
down as I tried to copy new files onto the original 6GB disk.
It just shut itself off!
I removed the PCI wireless card, and it stayed up a little
longer. While toggling power I saw the fan surge on and off
in about three second cycles, in the way that I saw it surge
once before, when the power adaptor went out.
Considering all the evidence, it sounds like the power is
bad. Do y'all have any suggestions? I don't mind springing
for another power unit, but I'd like to make sure that it stays
up for awhile. Is there a power unit available with more
capacity? Will removing it from the UPS it is currently using
help (due to the funky power coming out of cheap UPSes)?
Is there a good cheap place to buy power units (the cheapest
I've found online costs $76)?
