Hi Everyone,
Is it possible to use send/recv to change the recordsize, or does each
file need to be individually recreated/copied within a given dataset?
Is there a way to check the recordsize of a given file, assuming that
the filesystems recordsize was changed at some point?
Also - Am I right in thinking that if a 4K write is made to a filesystem
block with a recordsize of 8K, then the original block is read (assuming
it's not in the ARC), before the new block is written elsewhere (the
"copy", from copy on write)? This would be one of the reasons that
aligning application IO size and filesystem record sizes is a good
thing, because where such IO is aligned, you remove the need for that
original read?
Thanks,
Tristan
