Hi guys, In the RAIDZ implementation of ZFS - there is a concept called Dynamic Stripe. I read that Every block is its own RAID-Z stripe, regardless of blocksize. Can any body pour more light on this. Like how this dynamic stripe actually works, how it is implemented on disk etc., Regards Ganesh This message posted from opensolaris.org
Hi. With traditional Volume managers (or hardware raid) when you create raid 0, 10, 5, ... you''ve got fixed (specified during creation) stripe width. With zfs stripe width is not fixed. In case of raid-z every block is it''s own raid-z stripe which means that when you write a block (which is also variable in size) then stripe size used to write this block will be the same size (I guess). I also guess that it''s the case for other raids in zfs. This message posted from opensolaris.org
