OK, so here's what I've seen with this. First it will run a Smartpools job. After that, it will run a FlexProtect and a FlexProtectLin job to actually fail out the SSDs. In case any one else wonders, because Isilon won't tell you this, apparently.
I am enabling L3 on a couple of node pools in my cluster, one of which is new (S210s), and one of which is old (S200s). I have put them in their own tier, and am running Smartpools to clean stuff up. However, I do not see the SSD usage decreasing on these nodes as I would expect so the SSDs can be failed out. The admin guide and support are not particularly clear on this (support just copied the bit from the guide), so has anyone done this? I'm actually seeing SSD usage increase on the S210s.   Do I need to run FlexProtectLIN on these to get rid of the SSDs so they can be used for L3, or is it truly a completely invisible background process like the admin guide seems to indicate?   --Ken
