So I have been playing with a RAID 10 f2 ( 2 disks far layout) setup...thanks for all of the advice..Now I am playing with the format and want to make sure I have it setup the best that I can, my raid was built using the raid 10 option with 2 disks with the layout=far, chunk size 512....now I read all of the docs I could find about format and stride and stripe size and this is what i came up with... mkfs -t ext4 -E stride=128,stripe-width=32 /dev/md0 Someone let meknow if this looks right, but since i only have two disks to get my stride 512/4k=128 and then to get my stripe 2/2*128/4=32 Does that look right and if not let me know but more important how to obtain the right number so I can do it correctly in the future...Thanks. -------------- next part -------------- An HTML attachment was scrubbed...
