I found a sentence in the HOWTO:
"raid1 and raid 10 always writes all data to all disks"
I think this is wrong for raid10.
eg
a raid10,f2 of 4 disks only writes to two of the disks -
not all 4 disks. Is that true?
I suspect that really should have read "all mirror copies," in the
raid10 case.
OK, I changed the text to:
raid1 always writes all data to all disks.
Just to be really pedantic, you might say "devices" instead of disks,
since many or most arrays are on partitions. Otherwise I like this, it's
much clearer.
raid10 always writes all data to the number of copies that the raid holds.
For example on a raid10,f2 or raid10,o2 of 6 disks, the data will only
be written 2 times.
