hi all,

I would like to use coda as a kind of backup system, where I 
periodically write dumps onto. Such that the system can restore from any 
host (replicate) if the real system is down. the files are around 
200-400 MB each. my servers have about 500 MB RAM and 4 GB swap files.

now i have 40GB of vicepa storage. i have a question about how to tune 
the LOG and the DATA files in order to be able to store those files.

copying yielded on venus: no space left on device;

currently my DATA file is 32 MB
my LOG file is 20 MB

the vicepa has only 8.3 MB data.
copying a 7MB file worked wihtout a problem...

on the server it showed the following:
