How can I verify the read speed of a btrfs raid0 pair in archlinux.?
I assume raid0 means striped activity in a paralleled mode at lease
similar to raid0 in mdadm.
How can I measure the btrfs read speed since it is copy-on-write which
is not the norm in mdadm raid0.?
Perhaps I cannot use the same approach in btrfs to determine the
performance.
Secondly, I see a methodology for raid10 using the command....mkfs.btrfs
-m raid10 -d raid10 /dev/sda/dev/sdb /dev/sdc /dev/sdd...
Can I apply the parameters above for -m and -d for raid0?
If using raid0 for two devices and add another device, is it striped as
raid0 also or does the system change it to raid1.
What happens to the speed of the system when a new device is added? Is
it increased ?
Much I have at hand for mdadm software raido and it doubles the read
speed. What parallel exists in raid0 btrfs? Or is it completely off
base to expect a speed increase?
