[OpenAFS] Strange backup volume behavior

[Rick Cochran]

Hello, John of printing fame!

After rehabilitating my typing fingers, as Andrew Deason suggests, I get
the following:

samuel> ls /afs/.afsdemo.cit.cornell.edu/users/rcc2
afs  Private  Yesterday
samuel> ls /afs/.afsdemo.cit.cornell.edu/users/rcc2/Yesterday
ls: cannot access /afs/.afsdemo.cit.cornell.edu/users/rcc2/Yesterday:
Connection timed out
samuel> fs exa /afs/.afsdemo.cit.cornell.edu/users/rcc2/Yesterday
fs: File '/afs/.afsdemo.cit.cornell.edu/users/rcc2/Yesterday' doesn't exist
samuel> fs lsm /afs/.afsdemo.cit.cornell.edu/users/rcc2/Yesterday
'/afs/.afsdemo.cit.cornell.edu/users/rcc2/Yesterday' is a mount point
for volume '#rcc2.backup'
samuel> vos exa rcc2.backup
rcc2.backup                       536870926 BK    1000930 K  On-line

      number of sites -> 1
         server avoca01.serverfarm.cornell.edu partition /vicepb RW Site
samuel> fs rmm /afs/.afsdemo.cit.cornell.edu/users/rcc2/Yesterday

samuel> chmod 775 /afs/.afsdemo.cit.cornell.edu/users/rcc2/Yesterday
chmod: cannot access

samuel> ls /afs/.afsdemo.cit.cornell.edu/users/rcc2/

samuel> fs mkm /afs/.afsdemo.cit.cornell.edu/users/rcc2/Yesterday
rcc2.backup
samuel> fs exa /afs/.afsdemo.cit.cornell.edu/users/rcc2/Yesterday
fs: File '/afs/.afsdemo.cit.cornell.edu/users/rcc2/Yesterday' doesn't exist

But then:

samuel> fs checkvolumes
All volumeID/name mappings checked.
samuel> fs exa /afs/.afsdemo.cit.cornell.edu/users/rcc2/Yesterday
File /afs/.afsdemo.cit.cornell.edu/users/rcc2/Yesterday (536870926.1.1)
contained in volume 536870926
Volume status for vid = 536870926 named rcc2.backup
Current disk quota is 1100000
Current blocks used are 1000930
The partition has 9050308 blocks available out of 10208244

What I did previous to losing track of this backup volume was to move
volume "rcc2" from one server to another.  Should that cause this kind
of behavior?
