Hi,
I'm trying to unload I/O on a bussy server (about 100M/bit Internet link
and 3000 ISP customers), by splitting cache_dir on two different
storages(and media) as an starting point (later I would like also to use
SMP features, but for now I'm getting too many errors)
What I'have done is
workers 1
cache_dir rock /var/spool/squid/rock 10000 max-size=31000
max-swap-rate=250 swap-timeout=350
cache_dir aufs /var/spool/squid/aufs 300000 16 256 min-size=310001
But this results in the rock storage growing and the aufs storage not.
root@proxy:/etc/squid3# du -h --max-depth=1 /mnt/cache/squid3/
100K /mnt/cache/squid3/aufs
206M /mnt/cache/squid3/rock
As you can see the aufs storage size is the same as when it was
initialized and after hours having squid running it keeps the same.
Any help will be preciated.
