Hi,
Our squid servers are consistently goes over their configured disk
limits. I've rm'ed the cache directories and started over several
times... yet they slowly grow to over their set limit and fill up the
filesystem.
These are du -sk's of the squid directories:
squid2: 363520856 /squid/
squid3: 343399160 /squid/
squid4: 356593016 /squid/
Okay so, about 350 GB per disk is used....
These are clearly over the 300,000K limit -- and the swap stat files
are less than 1MB.
Um, you mean the 300 GB limit configured. 307,200,000 KB to be precise.
cachemgr.cgi says we are using way less:
Store Directory Statistics:
Store Entries : 5698
Maximum Swap Size : 307200000 KB
Current Store Swap Size: 275852960 KB

Which indicates that something other than Squid data cache is going into
those disks. OR, the unlinkd eraser process is not working.
We're storing large files, some can be several GB in size.

You may want to locate and remove the "none" files created by the above
logging. If they are in /squid/cache that is likely your problem.
cache_log contains the critical and important administrative messages
when things go horribly wrong. There may be something logged there that
will make your problem clearer.
