On a squid 2.7 Stable 6, 2 CPU 3.6 Ghz, 10 GB ram, 1 raid1 300gb disk, partition /u02 is ext3 mounted with noatime, noatimedir, I have these two cache_dirs - the setup for coss I took from a previous message : cache_dir aufs /u02/squid 150000 256 256 min-size=4288 cache_dir COSS /dev/cciss/c0d0p5 38000 max-stripe-waste=32768 block-size=4096 maxfullbufs=10 max-size=524289 During normal use, I see that almost all objects are sent to the coss storage, and only big ones ( > 550 KB ) are sent to the aufs storage. Actually it stores flv, swf, jpg.... If I stop squid and restart it, during the time coss reads its stripes I get SO_FAIL error for objects less than 4288 bytes (and it is correct), and I have objects more than 4288 bytes long correctly stored to aufs... >From what I understand, these cache_dirs say: - objects less than 4288 bytes ALLWAYS to coss - objects more than 524289 ALLWAYS to aufs - objects more than 4288 bytes AND less than 524289 split to aufs and coss.... But I'm probably wrong... .. can you tell me what is wrong in my reasoning ? Because 524289 is probably too big for 38 gb coss.... Thank you, Francesco PS: Mean Object Size: 30.65 KB
