I am using rock on one of SSD drives to check its performance . before choosing rock the filesystem was reiserfs because it shows good performance in huge number of little files but i read somewhere the rock uses one big file . so i choose ext4 with discard to got the benefits of discard/trim . the rock creates one file with the name rock in /cache2 directory with the size 105906MB from begin and still it has same size . but "df " shows 27% used and grows each day . 1. is the max-size=31000 is the maximum size rock may store ? if not what is the max safe value ? 2. is my fstab line shows bellow optimal for rock ? i have created it with "mkfs.ext4 /dev/sdb" on OCZ-VERTEX3 120GB 3. it seems the the disk is more idle since switched to rock . how to force it use the disk more aggressive ? 4. the following is output of dumpe2fs of that drive . is it better to resize the block size to 32KB which is the size of rock store size ? any other suggestion for filesystem ? dumpe2fs /dev/sdb | more -- View this message in context: http://squid-web-proxy-cache.1019090.n4.nabble.com/rock-questions-tp4662816.html Sent from the Squid - Users mailing list archive at Nabble.com.
