[zfs-discuss] Metaslab alignment on RAID-Z

2006-09-26 Thread Chris Csanady
I believe I have tracked down the problem discussed in the "low disk performance thread." It seems that an alignment issue will cause small file/block performance to be abysmal on a RAID-Z. metaslab_ff_alloc() seems to naturally align all allocations, and so all blocks will be aligned to asize o

Thanks, Chris, for digging into this and sharing your results. These seemingly stranded sectors are actually properly accounted for in terms of space utilization, since they are actually unusable while maintaining integrity in the face of a single drive failure. The way the RAID-Z space accountin

I've found a small bug in the ZFS & Zones integration in Sol10 06/06 release. This evening I started tweaking my configuration to make it consistent (I like orthogonal naming standards) and hit upon this situation: - Setup a ZFS clone as /zfspool/bluenile/cloneapps; this is a clone of my global
