In the last episode (Aug 11), Dick Hoogendijk said:
Where does ZFS keeps its data *on disk* for created/exported/imported
vdevs?
Is /etc/zfs the only place or are there other places?
Thanks.
I don't think there's anything in /etc/zfs apart from the NFS exports file.
The list of currently-mounted pools and their devices is stored in
/boot/zfs/zpool.cache , and I believe is only used during bootup. vdev
information itself is stored in the zpool labels; you can view that with
zdb -l /dev/nnn, where nnn is one of the devices your zpool is bulit on.
More info than you probably want:
