Hi Niall, I noticed that ZFS won't automatically import pools myself. I didn't really consider it a problem since I wanted to script a bunch of stuff on USB insertion. I was hoping to be able to write a script that would detect the insertion, attempt to automatically mount pools on devices

I have been reading this forum for a little while, and am interested in more information about the performance of ZFS when creating large amounts of filesystems. We are considering using ZFS for the user's home folders, and this could potentially be 30'000 filesystems, and if using snapshots

I believe the answer is in the last email in that thread. hald doesn't offer the notifications and it's not clear that ZFS can handle them. As is noted, there are complications with ZFS due to the possibility of multiple disks comprising a volume, etc. It would be a lot of work to make it work

Hey guys, This may be a dumb thought from an end user, but why does it have to be hard for ZFS to automatically mount volumes on removable media? Mounting single volumes should be straightforward and couldn't you just try to import any others and just silently fail if any required pieces are
