A frantic Friday
Jun. 12th, 2009 09:27 pmToday has been even tougher than I predicted yesterday, thanks to a combination of manic firefighting at work and frantic philosophy writing.
Work, in particular, was a real slog, with the day capped by a particularly nasty HSM problem on the old machine which started when we brought down Unitree in an attempt to clear a problem with a non-existant cap. The software shut itself down successfully — always a relief — but, when we attempted to restart it, the tape movers complained that their network port was busy and refused to come back up. Reconciled to a reboot, I started quiescing the batch subsystem and cleared out a whole load of stale
I'm still not entirely sure what happened but my best guess is that one of the ports normally used by Unitree had been grabbed by an
My philosophy work too, was a bit of a death-march, but I managed to finish my current chapter ready for today's deadline. It was rather weak, with too much exposition and not enough argument, but hopefully it's enough to give an idea of the sort of thing I'm aiming for.

ftpd processes. Just as I was about to start bringing the OS down, operations called me to say that the movers had just restarted themselves and that the reboot was no longer necessary.I'm still not entirely sure what happened but my best guess is that one of the ports normally used by Unitree had been grabbed by an
ftpd process which had hung because the HSM NFS archive directory hadn't been unmounted correctly when the software was first taken down. This ftpd process then blocked all the subsequent attempts to bring the HSM back up until I when through and kill them all off, freeing up the troublesome port in the process. Once I'd done this, taped, the tape service minder daemon, was able to bring the movers up, to kick start the tape server and to resume normal production.My philosophy work too, was a bit of a death-march, but I managed to finish my current chapter ready for today's deadline.
