I am using SUSE 11SP3 and formatted the devices with a block size of 4KB using mkfs.ext3.
/sys/block/sda/queue/physical_block_size show the OS is using 512 bytes.
- How can I change the OS block size to match the 4KB FS block size?
- I created a RAID0 array form the disks. Do I need to change the block size of the RAID array and the disks it is comprised of or should I only change the RAID0 array?
