This is RFE 6425091 "want 'zfs diff' to list files that have changed between snapshots", which covers both file & directory changes, and file removal/creation/renaming. We actually have a prototype of zfs diff. Hopefully someday we will finish it up... --matt Henu wrote: Hello Is there a p

[zfs-discuss] unionfs help

Is it possible to emulate a unionfs with zfs and zones somehow? My zones are sparse zones and I want to make part of /usr writable within a zone. (/usr/perl5/mumble to be exact) I can't just mount a writable directory on top of /usr/perl5 because then it hides all the stuff in the global zone.

Re: [zfs-discuss] Best 1.5TB drives for consumer RAID?

Sounds good. I was taking a look at the 1TB Caviar Black drives which are WD1001FALS I think. They seem to have superb user ratings and good reliability comments from many people. I consider these "full fat" drives as opposed to the LITE (green) drives, as they spin at 7200 rpm instead of 5400

Re: [zfs-discuss] Best 1.5TB drives for consumer RAID?

That's a pity about smartmontools not working. Which controllers are you using? Good news about no sleeping though, although perhaps not so economical. I think I'd rather burn a bit more power and have drives that respond properly than weird timeout issues some people seem to be experiencing wit

smartmontools doesn't work with my controllers. I can try it again when the 2 new drives I've ordered arrive. I'll try connecting to the motherboard ports and see if that works with smartmontools. I haven't noticed any sleeping with the drives. I don't get any lag accessing the array or any er
