When I set up my INN server I had allocated a number of large cycbuff to
various metacycbuff
I now find that I really should have changed the allocation of how many cycbuff
were assigned to each metacycbuff
The current setting is
metacycbuff:BIG8:BUFF01,BUFF02:SEQUENTIAL
metacycbuff:ALT:BUFF03,BUFF04:SEQUENTIAL
metacycbuff:BIN:BUFF05,BUFF06,BUFF07,BUFF08:SEQUENTIAL
metacycbuff:CTCALL:BUFF09,BUFF010:SEQUENTIAL
As I don't really carry any binaries (and had set this configuration up much
earlier in the process before this dawned) I was to use some of the cycbuff
currently assigned to BIN and move them to the other metacycbuff.
Sometime ago I recall stopping the server and changing the allocation of
cycbuffs assigned to metacycbuff but then hit issues with permissions to write
to cycbuff or similar. Can't recall.
What is the best way to reassign cycbuffs to different metacycbuffs?
In the case of the cycbuff I want to look at each has a minimal amount of data
written to them (68.4 MB, 1.6MB, 1.6MB, 1.6MB)
Buffer Class Size Used %Used Cycles KB/sec Days
BUFF01 BIG8 50.0 GB 4.1 GB 8.2% 0 0.37 1641.85
BUFF02 BIG8 50.0 GB 1.6 MB 0.0% 0 0.00 0.00
BUFF03 ALT 50.0 GB 4.7 GB 9.4% 0 0.41 1491.45
BUFF04 ALT 50.0 GB 1.6 MB 0.0% 0 0.00 0.00
BUFF05 BIN 50.0 GB 68.4 MB 0.1% 0 0.07 8691.68
BUFF06 BIN 50.0 GB 1.6 MB 0.0% 0 0.00 0.00
BUFF07 BIN 50.0 GB 1.6 MB 0.0% 0 0.00 0.00
BUFF08 BIN 50.0 GB 1.6 MB 0.0% 0 0.00 0.00
BUFF09 CTCALL 50.0 GB 14.1 GB 28.2% 0 1.27 479.32
BUFF10 CTCALL 50.0 GB 1.6 MB 0.0% 0 0.00 0.00
TOTAL: 10 - 500.0 GB 23.0 GB 4.6% 0 0.67 -
Thanks for any advice guys :-)
Best, Paul.

I haven't done this in a long time, but I thought only the cycbuff, not
the metacycbuff, was noted in the storage API tokens. So I think you can
just move the buffers to a different metacycbuff and restart INN and
things will Just Work.
Yeah, looking at the CNFS code, I think that's correct.
I don't see any reason why you'd have permission issues, since INN is
currently writing to all of those buffers anyway.
