New admin: inn2.2.1 vagaries of cnfs, recovery

[Grant Basham]

I am running inn2.2.1 on RedHat6.1 linux.  Setup cnfs with 2 2-GB buffers
for alt.binaries.  


A.  When I run cnfsstat the buffers look underused:
...
Class BINARIES  for groups matching "alt.binaries.*"
 Buffer THREE, len: 1953.12 Mbytes, used: 1482.25 Mbytes (75.9%)  60 cycles
  Newest: 1999-12-16 11:01:10,    0 days,  0:00:02 ago
  Oldest: 1999-12-16  9:04:47,    0 days,  1:56:25 ago
 Buffer FOUR, len: 1953.12 Mbytes, used: 1538.56 Mbytes (78.8%)  60 cycles
  Newest: 1999-12-16 11:01:11,    0 days,  0:00:01 ago
  Oldest: 1999-12-16  9:04:15,    0 days,  1:56:57 ago
...

Often they are down less than 40% utilization.  Is this expected?


B.  Obviously, I need a lot more disk space.  Can I just patch in
extra file/buffers or have I got to kill/restart.

C.  Ran out of admin disk space.  History rebuild, etc failed.
ran a makehistory as per the man page and it seemed to rebuild
ok.  Was concerned that the overview/uniover databases were
out of date but was not clear what to do.  What all needs to
be done on a recovery from out-of-space in admin area?

D.  There is a lot of traffic on problems with 2.2.2 update on
newsgroup.  No info on successes.  Is update rebuild apparently
going ok for most.  Reply to this one to me rather than list and
I will summarize results next wednesday to the list.

Thanks for help
