Gentle admins: Has anyone done any testing to see what the right reserved block percentage (-m to tune2fs or mke2fs) is? On the Berkeley Fast Filesystem the right number was 10%; the ext2/ext3 default is 5% so I assume that's pretty good for most Linux. But with so many layers between Linux and the hardware, is that a good default on zSeries?
I ask because we've just noticed that Levanta left us with filesystems where -m was 0. That gives us an interesting time with filesystem monitoring (if you want an alarm at 90% of capacity, does it trigger at 90% of the total blocks or 85.5%?), but we're also wondering if we have any performance-related time bombs. Thanks for any help!
