Single SSD Feeder disk - Duplicated pool

hopester

If you want to use a single feeder disk to duplicated pool this feature is now working correctly with the latest beta (1.3.2.7545). To use the feature carry out the following steps.

• Install the Archive Optimizer plugin.
• Optional:If you wish to set your own duplication time slot do the following extra step 

Locate the DrivePool.Service.exe.config_default file in C:\Program Files\StableBit\DrivePool and rename to  DrivePool.Service.exe.config

Edit the file and set the FileDuplication_DuplicateTime to whatever time you wish. 

• Configure the plugin how you wish specifying which disk is the feeder and the others archive drives.
• Ensure only the Archive Optimizer balancer is enabled.
• Set the automatic balancing time 1 hour before the duplication time.
• Select the duplicate files later option in drivepool server settings.
• Reboot.

Drivepool will then copy all new files to the single feeder disk then once a day move all the files off the feeder to the pool and duplicate. I use this option as I had a spare SSD drive and because if I copied a large iso bluray rip to the pool, if that file landed on a drive that was already streaming video content to a client in the house, it would cause buffering due to the hard drive having to read/write at the same time. With an ssd drive that is not an issue as it can handle the read/write IO at the same time.

Hope this helps if someone else is thinking of trying it out.

p.s. be careful if you select a sandforce based ssd as they can have issues with trim with data like video files that cant be compressed. Its best not to fill those drives over 70% going by information on anandtech.
