Oh well thats a good catchya! If I do use the 4*500gb disks They cannot be removed from the pool and thus I would need to create a new pool, copy all data there and destroy the original pool. Which could be very problematic if I only have 6 sata ports and I've used them all... I shall stick with the 10tb mirroring the 6tb for 6tb of storage. The day I need more I will replace it with a 10tb and move the 6tb to the offsite backup to increase its size to 10tb as well.That's right, you could add a second (and third) mirror vdev to your pool later but you cannot remove a vdev from a pool after adding it. So attempt to plan wisely.
A more beneficial experience would be to replace the 6 TB disk by a second 10 TB disk at some time in the future (expands usable storage distinctly) and then to buy a second 6 TB disk (adding a mirror of two 6TB disks to a then existing mirror of two 10 TB disks will expand usable storage distinctly as well).
And don't forget to read cyberjock's slideshow.
Also, I started reading that pdf, great info! You guys should add that on the very frontpage with a hard link of this forum! (Did I miss it?)
So then my last question:
If I do:
zfs send -Rv HomeVol@snapshot_name | zfs receive -Fdu pool2
(where pool2 resides on 10tb temp volume)followed by destroying HomeVol and recreating it with only a 6tb drive, and then:
zfs send -Rv pool2@snapshot_name | zfs receive -Fdu HomeVol
.Lastly a
zpool attach HomeVol 6tbdisk 10tbdisk
.Whats my best shot at keeping my services (like smb etc), permissions (should just come along with the send/recieve commands of snapshot, right?), and jails.
Should I stop them, and restart them after all this is done and hope they just work, or set them up again from scratch?
Many many thanks for all help here so far!
