Ticket Resolution Summary Owner Reporter
#485 fixed make sure 6.824 isn't using the Athena 9 install script broder geofft

Reported by geofft, 15 years ago.

Description

We have libfuse-dev and the fuse kernel module and all the other fun stuff 6.824 wants; someone should quickly double-check that they realize this and aren't telling students to use the sketchy sketchy Athena 9 installer

#493 fixed /proc/mounts! It's over sixty-five thousand! geofft

Reported by geofft, 15 years ago.

Description

I logged in to a cluster machine today. /proc/mounts had 65571 entries in it, including 63356 instances of what appear to be bind-mounts of /media. My xterm that I launch from .startup.X started after about two minutes at a black screen. GNOME took a while longer, and I noticed this issue because stracing gnome-terminal indicated it was trying to read /proc/mounts and that was taking a long time. I think this is what people are reporting when they say some cluster machines take them several minutes to log in...

See  /mit/geofft/Public/proc-mounts-uniq-c for the output of cat /proc/mounts | uniq -c and  /mit/geofft/Public/debathena-over-65000 for the relevant kernel logs wherein I pressed alt-sysrq-T and -W a bunch.

#496 fixed fix cluster-login-config for Lucid jdreed geofft

Reported by geofft, 15 years ago.

Description

Says Evan: "There are going to be things that break in cluster-login-config. I don't know what they are... I'd have to look at the package."
