I also experimented 1k block size on GFS1. Although you can improve the disk usage using a smaller block size, typically it is recommended to use the block size same as the page size, which is 4k in Linux. I don't remember all the details of results. However, for large files, the overall performan

2010-12-17 Thread Jeff Sturm
One of our GFS filesystems tends to have a large number of very small files, on average about 1000 bytes each. I realized this week we'd created our filesystems with default options. As an experiment on a test system, I've recreated a GFS filesystem with "-b 1024" to reduce overall disk usage a

Hello again, I'm planning to run GFS cluster of two nodes on some SAN storage over fabric - 4TB ( 5 disk in RAID 5 - with stripe 128k). I'm having some mixed feelings about setting the GFS block size for my fs... The nodes are going to hold some WWW files (let say for video streaming) which can be
