In the log, I see, that kid5 is coordinator:
2013/01/08 11:15:46 kid5| Process Roles: coordinator
The following workers (workers 4) are now running (everything seems
working fine):
squid 28254 0.1 0.0 21052272 16032 ? S 11:15 0:00
(squid-coord-5) -f /etc/squid/squid.conf

squid 28256 0.1 0.0 21125112 19520 ? S 11:15 0:00

squid 28257 0.1 0.0 21125404 20960 ? S 11:15 0:00

squid 28258 0.1 0.0 21125096 16760 ? S 11:15 0:00
(squid-1) -f /etc/squid/squid.conf
After reconfigure, I got this error:
2013/01/08 11:15:11 kid5| /squid-cache05/swap.state: (2) No such file
or directory
FATAL: commonUfsDirOpenSwapLog: Failed to open swap log.
Squid Cache (Version 3.2.5): Terminated abnormally.
The error is OK, because there is no directory /squid-cache05.

With four workers configured, I have these processes:
squid 28254 0.1 0.0 21052272 16032 ? S 11:15 0:00
(squid-coord-5) -f /etc/squid/squid.conf

squid 28256 0.1 0.0 21125112 19520 ? S 11:15 0:00
(squid-3) -f /etc/squid/squid.conf
squid 28257 0.1 0.0 21125404 20960 ? S 11:15 0:00

With the configuration above (your propose), every kid-process owns
ALL cache-dirs (shown with squidclient mgr:storedir). I think, this is
odd.
When I configure four cache_dirs with the variable ${process_number},
then one kid own one storedir -> this seems ok.

I tried beginning with squid-cache00, but I think there's not
squid-process 0, which access this volume. Isn't it beginning counting
with 1?
