It is the amount of VM that matters, with the private mmapings there should be a lot less disk trashing when the RVM size exceeds the amount of physical ram, as unmodified pages are not swapped out/in but simply paged in from the RVM data file.

One problem we still have is that on linux it is not yet possible to do a private mmap of a raw device, but hopefully that will be resolved soon in the development kernels. Talk about implementing it has already started.

Ehh, config.tape, I don't thing we have one, ah yes... This is the one on our backup server.

-8<--------------------------------------------------------

sleep_interval 200
backupmachine dvorak.coda.cs.cmu.edu

notify "/usr/sbin/zwrite -v -d -n -c backup -i coda " #message "echo "
message "mail -s 'Backup notification' admin_at_coda.cs.cmu.edu"

-8<--------------------------------------------------------

These are the configurable options and their defaults:

dbdir		"/vice/db"
labelsdb	"/vice/db/TAPELABELS"
sleep_interval	200
notify_cutoff	5
maxretries	25
backupmachine	undefined
message		undefined
notify		undefined

I know, haven't checked what the cause is yet. It is possible to generate a tokenfile with `tokentool' and use that one from the commandline with "-fromfile token", so it is either the parsing/reading of the password, or the RPC message sent to the auth2 server.
