I have a question about hierarchical pools. I have an existing Pool containing 9 disks, with a variety of duplication on various folders. I also have available several SSD's which I would like to use as accelerators for the pool, but I would prefer to avoid 'wasting' space on these by duplicating. So, thinking hierarchical pools could solve this I set out to build the following set of pools .....
Pool H (new pool, the root of my hierarchy)
/ \
/ \
Pool A (new SSDs) Pool B (existing pool 9 disks)
Pool H would not be duplicated, but would mark Pool A as being an SSD drive, and Pool B as being an Archive drive.
When I did this and opened a file browser on Pool H, there was nothing showing!! However when I browse Pool B, all my data is there.
The question is how do I "populate" Pool H with the data from Pool B?? and if this involves physically moving files on Pool B, how do I retain the replication behavior on Pool B?
Any hints? Or am I completely misunderstanding how hierarchical pools work?
