Hi, great, thank you. So ZFS isn't picky about finding the target fs already created and attributed when replicating data into it. This is very cool! Best regards, Constantin Darren J Moffat wrote: Constantin Gonzalez wrote: Hi Darren, thank you for the clarification, I didn't know

[zfs-discuss] zfs pool unavailable!

2008-02-29 Thread Justin Vassallo
Hello, I have a zfs pool on 3 external disks, connected via usb. All 3 disks are fine and can be seen from rmformat. They all appear on the same nodes as they were before the restart (this problem started following a reboot). However, the zfs system is not recognizing them. Any clues?
