I actually stumbled upon this last night backing up my computers. Thing is, I got several platforms, so not only vhd's, and would like to exclude the disk images folders instead of particular files. Is this possible ?
Create a rule for that specific folder, Uncheck the disks that you don't want the files to reside on.
So I was experimenting a bit, when it hit me that I might do a workaround by having a pool of SSD inside the original drivepool. Will this help or is it still an issue with big files, biggest SSD must be bigger than the big file ?
Yes. StableBit DrivePool stores the actual files on the underlying disks. that means that any file you add to the pool must be able to fit onto the disk(s) in the pool. So if you're using an SSD, the file must be small enough to fit on the SSD. So, larger SSDs are a good idea, especially if you plan on using the SSD Optimizer balancer plugin.
An update here, since even having 1 ssd drivepool in the main drivepool as cache wont work (i guess), i made a storage space of the 2 ssds and added them to the main drivepool.
Now I got 330gb of SSD write cache. But I need to force DrivePool move EVERYTHING from that "disk" (again 2 ssds in SS) as soon as I am done writing to the file to make room for the next file. How do I achieve this Christopher ?
To clarify, you want everything to be written to the SSD drive(s) and then moved off?
If so, then you want the SSD Optimizer Balancer.
Install it and enable it, and configure it.
Though, keep in mind, that if you're using duplication, you really need two disks for this. And two PHYSICAL disks.
Additionally, if you're using File Placement Rules along side of the SSD Optimizer, check the notes for recommended configuration.
And to make sure this happens immediately, make sure that in the balancing settings, that it's set to "balance immediately".
