Hello,
Is it possible to spin down disks/put them in idle/standby mode, which are using ZFS? I suspect there might be issues depending on how ZFS access these disks but I wasn't sure from the info I found. As a note, I tried both camcontrol(8) and ataidle. What happens is that disks do spin down but immediately spin up again after issuing these commands. After that however, they never spin down again.
Finally is it even practical to spin down disks like this from time to time? The power consumption might add up with large number of disks, which might matter for something like home NAS solution/desktop.
Any suggestions welcome.
