Hi,
I have a weird problem with one of the hard drives spin-down (going into standby mode) in 4 minutes and 30 seconds on its own and I haven't found a way to stop that.
I'm running OMV5 on a Lenovo laptop W540. Two WD red 10TB hard drives are configured as mirror mode in ZFS. This laptop has M.2 slot and I used it for the boot drive. It has 2 SATA interfaces available, one from the original hard drive and another on the optical drive. Even though I set the same disk configuration to disable all power management on both drives. The drive that connects to the original optical drive SATA interface will always spin-down in 4 minutes and 30 seconds. The other hard drive has no problem and never spins down. I tried to swap the drive and found out the problem sticking with the physical interface (optical SATA), not with the particular hard drive.
I'd like to get help on how to prevent that hard drive from spinning down. Thanks a lot.
