This message is for whoever has recently been copying Linux files onto
ninas.mit.edu via NFS.
Over the past few days the server sipb-nfs.mit.edu (canonical name
bloom-picayune.mit.edu) has been inaccessible often due to it wedging
or crashing. At SIPB, we are not yet sure of the cause or causes of
this problem, but there seems to be some correlation between the times
of the wedge/crash occurrences and times during which there were NFS
mounts of sipb-nfs from ninas.mit.edu (IP address 18.74.0.125).
This afternoon I noticed that ninas was accessing the Red Hat 6.0
packages under /redhat/6.0/i386/RedHat/RPMS. A few months ago we
noticed a problem with the sipb-nfs server wedging or crashing
whenever it was accessed by machines running a Linux 2.2.x kernel (see
http://www.mit.edu:8008/charon/linux-dev/2614). Over the past few
days, has ninas at times been running Red Hat 6.0 or another system
based on a Linux 2.2.x kernel? The approximate times of the
wedge/crash occurrences were Friday at 00:43, Monday at 12:51, and
Monday at 14:55. Were you accessing sipb-nfs.mit.edu at some or all of
those times (or, within a few hours preceding those times)?
In any case, regardless of whether ninas has been using the Linux
2.2.x kernel, having the Red Hat 6.0 RPMs available on the sipb-nfs
server could perhaps be seen as encouraging persons with Red Hat 6.0
systems to access this server via NFS, thus perhaps triggering the
wedge/crash issue. So, for now I have made the /redhat/6.0 directory
tree inaccessible (everything had been mode 644 or 755, and I did a
"chmod -R go-rwx").
Although we may later make the directory tree accessible in order to
work on our own Red Hat 6.0 development, for now please hold off on
accessing this server while we see how we can resolve the wedge/crash
issue. Probably at a later point SIPB will be making Red Hat 6.0 files
available -- this could potentially be on sipb-nfs.mit.edu or possibly
a different server -- and we'll let you know when we have that ready.
For now, one place on MIT's network with a publicly available copy of
Red Hat 6.0 is ftp://rpmfind.net/linux/redhat/redhat-6.0/
