I understand that the COW design can fragment files. I'm still trying to understand how that would affect a database. It seems like that may be bad for performance on single disks due to the seeking, but I would expect that to be less significant when you have many spindles. I've read the following blogs regarding the topic, but didn't find a lot of details: http://blogs.sun.com/bonwick/entry/zfs_block_allocation http://blogs.sun.com/realneel/entry/zfs_and_databases This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
