Hi there,
today I came across a problem: I have a cell with /afs like
# ls /afs
.agricola-gymnasium.de
agc -> agricola-gymnasium.de
agricola-gymnasium.de
#
agricola-gymnasium.de is a mountpoint for #root.cell; I had a RO copy of
root.cell. To make things simpler (we've got only one server so far), I
tried to get rid of the RO copy. I removed the volume and the effect was
that /afs/agricola-gymnasium.de became unaccessible.
I tried to rmmount and mkmount it but it did not help. I had to
shutdown/restart the afsd. I found that quite annoying...
BTW: I used the situation to upgrade from 1.2.0 to 1.2.2. But starting
the 1.2.2 client produced an Oops. (I rmmod'ed the old libafs module,
the startup script took care of the rest.) ksymoops output is attached -
it looks a bit weird because of the ipv6 module which I do not use but
which is loaded automatically at system startup somehow (with usage
counter -1...).
Bye, Tino.

ksymoops 2.4.1 on i686 2.4.9. Options used
-V (default)
-k /proc/ksyms (default)
-l /proc/modules (default)
-o /lib/modules/2.4.9/ (default)
-m /boot/System.map-2.4.9 (default)
Warning: You did not tell me where to find symbol information. I will
assume that the log matches the kernel and modules that are running
right now and I'll use the default options above for symbol resolution.
If the current kernel and/or modules do not match the log, you can get
more accurate output by telling me the kernel version and where to find
map, modules, ksyms etc. ksymoops -h explains the options.
