AFAIK there is no complete guide for using FS types for squid . Historically i am using ReiserFS 3.6 on Ubuntu 12.10 64bit . Here is my /etc/fstab /dev/sda1 /cache1 reiserfs notail,noatime,nodiratime,data=writeback,barrier=none,async,commit=10 0 0 /dev/sdb1 /cache2 reiserfs notail,noatime,nodiratime,data=writeback,barrier=none,async,commit=10 0 0 /dev/sdc1 /cache3 reiserfs notail,noatime,nodiratime,data=writeback,barrier=none,async,commit=10 0 0 and root@cache:~# cat /sys/block/sd*/queue/scheduler noop [deadline] cfq And some references https://reiser4.wiki.kernel.org/index.php/Mount http://doc.opensuse.org/products/draft/SLES/SLES-tuning_sd_draft/cha.tuning.io.html sda id SSD and sdb,sdc are SCSI 19k RPM and i think they should not be same . Note :For people who are not aware , i suggest investigating on these configs because they are very important for performance tuning of cache server . Anybody has suggestions ? 2 more questions . 1 - Why squid does not going to implement its own FS ? even it may based on other filesystems . 2 - Why squid experts does not share their such configs and customizations on wiki ? -- View this message in context: http://squid-web-proxy-cache.1019090.n4.nabble.com/FileSystem-mount-options-and-other-parameters-tp4665275.html Sent from the Squid - Users mailing list archive at Nabble.com.
