LVM question

["William A. Mahaffey III" <wam%hiwaay.net@localhost>]

I have a newly commissioned NetBSD 6.1.5 server up & running AOK. It was 
built w/ the idea of adding some more storage after it was online for 
additional backup space on my LAN. The case is a mini-tower with 2 
unused 5.25" Bays, which can accomodate 8-12 2.5" HDD's using readily 
available accessories. I was originally planning to use a RAID10 of 
these drives for that additional storage. However, perusal of the web & 
man pages reveals that both ZFS & LVM2 are available for use. These are 
more storage efficient than a RAID10, with slightly less tolerance of 
plural HDD failures in the storage pool. Since I have had exemplary luck 
w/ 2.5" HDD's for several years now, I am willing to tolerate the risk 
for the additional usable space of either a ZFS or LVM storage setup. My 
question is: How reliable/mature are these under NetBSD ? LVM is 
obviously widely used by RHEL for years now, & believed to be 
mature/reliable enough for large enterprise settings. Is the LVM coding 
under NetBSD substantially identical to that under RHEL, absent 
necessary changes for porting ? Can anyone vouch for its reliability or 
lack thereof ? ZFS is pretty mature under FreeBSD, although the version 
under NetBSD seems to be a bit older according to Wikipedia (not a 
source I trust implicitly, but all I have for now). Has anyone onlist 
used ZFS under NetBSD 6.1.5 for mission-critical storage/backup ? Like 
it ? Hate it ? The online ZFS docs are somewhat ominous sounding, but 
undated, is development on both LVM2 & ZFS active & ongoing for NetBSD 
6.1.5 or higher ? Thanks for any info & have a nice weekend.
