[zfs-discuss] panic after zfs mount

Dear all We ran into a nasty problem the other day. One of our mirrored zpool hosts several ZFS filesystems. After a reboot (all FS mounted at that time an in use) the machine paniced (console output further down). After detaching one of the mirrors the pool fortunately imported automatically in

I found a thread that mentions an undocumented parameter -V (http://opensolaris.org/jive/thread.jspa?messageID=444810) and that did the trick! The pool is now online and seems to be working well. Thanks everyone who helped! -- This message posted from opensolaris.org

Well, for me it was a cure. Nothing else I tried got the pool back. As far as I can tell, the way to get it back should be to use symlinks to the fdisk partitions on my SSD, but that did not work for me. Using -V got the pool back. What is wrong with that? If you have a better suggestion as to

Thank you. The -D option works. And yes, now I feel a lot more confident about playing around with the FS. I'm planning on moving an existing raid1 NTFS setup to ZFS, but since I'm on a budget I only have three drive in total to work with. I want to make sure I know what I'm doing before I

Howdy all, I too dabbled with dedup and found the performance poor with only 4gb ram. I've since disabled dedup and find the performance better but zpool list still shows a 1.15x dedup ratio. Is this still a hit on disk io performance? Aside from copying the data off and back onto the
