Preparing your drives to be used in a FlexRAID storage pool

FlexRAID runs by default under the local system account on Windows or a specific user on Linux.
As such, the account under which FlexRAID runs must have full control over the drives that you intend to include in the storage pool.

Linux users: check the user’s permissions and grant as appropriate

Windows: Right click on each drive and ensure that the Local System account has full control as shown below.

    I noticed over several months of usage, my drives were going to sleep. It would take a very long time for them to wake on my first access of my drive pool in the morning…

    Then I started reading about Windows 7 performance tuning and power settings. I have never done it before, but a desktop machine first installed with the OS will have a setting to turn off drives after 20 minutes. This can cause FlexRaid to be very slow until all the drives in your pool wake from sleep settings. I would sometimes experience several minutes of delays when I would first try to access the drive pool; completely unacceptable performance no matter what the energy savings, for a server storage array.

    It was as easy as going into the control panel, Hardware and Sound, Power Settings, choosing High Performace Settings option, and then Change Plan Settings for that selection, and go to Advanced Settings, Hard Disk and setting Turn Off Hard Disk to NEVER.

    Now I experience ENTIRELY DIFFERENT PERFORMANCE from FlexRaid and I would never have known this from the FlexRaid documentation. I assume the developer is not entirely involved with Windows and has not experienced this complaint. Either way, make sure you understand this if you host FlexRaid on Windows.

      That’s not a complaint. That’s one of the big selling points of FlexRAID – allowing the drives to sleep when they’re not in use.
