Coda File System

venus mount of /coda fails

Pardon what may be a stupid question but I've been running around in
circles with this for awhile.

I'm trying to setup coda for the first time, I've setup the server
according to the HOWTO and that seems to be working, cmon is able to
talk to codasrv and the appropriate ports are open and daemons are running,
nothing bad sounding in SrvLog

This is just a testing setup so the configuration is almost exactly
what is in the HOWTO as an example, except I've installed under
/usr/soft/coda [and hacked the etc/*.init scripts to reflect this].

When I start venus, it tells me to try again with -init, so when I try
with -init I get:

One thing I notice at the top is that it refers to /usr/coda/LOG and
DATA, which don't exist, the LOG and DATA devices are files in
/home/coda for testing purposes.  I don't think this is the problem,

I also notice in out of coda-src/venus that the problem line
causing the above problem is:

      error = mount("coda", venusRoot, "coda",  MS_MGC_VAL,
                    islinux20 ? (void *)&kernDevice : (void

error is true so it fails as above.

I'm running linux 2.4.x [2.4.1-pre11 for the moment] with coda support
compiled in.  I've also tried it as a module with the same results.

Initially /coda didn't exist, so it failed to mount.  I tried simply
making the /coda directory and trying again, and now the kernel prints
an error everytime 'venus -init' runs:

coda_read_super: device index: 0
coda_read_super: rootfid is (0x7f000001,0x1,0x1)
Failure of coda_cnode_make for root: error -6

Should /coda exist as a directory or no?

Coda is version 5.3.12.

One possible wrench in the works is that all the filesystems on this
machine are reiserfs.  I'd be willing to revert my root fs back to
ext2 temporarily in the name of science if it would be useful.

Has coda been confirmed to work with 2.4.x?  Has it been confirmed to
work with reiserfs?  

Any help would be appreciated. 

Thanks a lot,
