So the thing is, I've been using zfs for a while but I'm not really sure how it works. In my mind it will look something like a cake, and I've made a picture.. just in case
I hope the image explains at least something (correct)
And I also was wondering how the adding and removing of vdev's worked. When I add a vdev to a pool does the new vdev stay empty or does it equalize with the rest of the pool? And if I remove a vdev, what happends to the data?
And what is the difference between scrub and resilvering? (also whats the time difference?)
And also, can someone give/get me some numbers on raidz with 6 vs. 8 disks? like transfer speed and resilvering time. I've heard that somewhere around 6-8 disks in a raidz the resilver time goes WAY up.
The thing is, I have a file server right now with 6x 1TB in RAIDz and has used about 80% of the space. So I was wondering how would things go if I start to add more space. I was thinking about adding 6 or 8 new 2TB disks in a RAIDz to my current pool. And so I was hoping someone here could come recommending and stuff, showering me in their wisdom.. (maybe that last part was a little to much..)
a little off topic, but getting these messages.. and I'm thinking its a sign of re0 dying?
note: added the picture as an attachment.. just in case, online imagehosting seems to be somewhat unreliable sometimes..
note 2: why would you set resolution limits on attachments?? Now I have to zip it, and that should be unnecessary.

Code:
re0: watchdog timeout
re0: reset never completed!
re0: PHY write failed
