Hey, so I was thinking about my power bill today .. I run 6 HDDs at once from a file server using zfs raidz2. This is great because it allows me to utilize the space as one contiguous block and not worry unless more than a single drive bites the dust.
... but... is there an option somewhere to power down the drives after X seconds of inactivity ? Can something be stored on a flash drive to keep the power utilization low and only power up the *right* disks when certain files are *read* ? How about when written ? Has anyone done this before ? Are there other options that make sense with this in mind that still have the resiliency of raidz or raidz2 ?
Using this feature could really make a dent in cooling and power bills for a lot of people where initial access time is not much of an issue !
I eagerly await a response!
