No, this is exactly how FlexRAID works also. The difference is that SnapRAID does only parity (and fake read-only pools but that's another topic altogether), vs. FlexRAID that does both in one software package and has one configuration option that does both behind the scenes. But it's just an illusion, it's still vitally important that all users understand that pooling and parity are vastly different and wholly unrelated to each-other, regardless of whether you use FlexRAID, SnapRAID, disParity, DrivePool, whatever...Flexraid doesn't work like this though right? It pools the drives and does parity too?
This is true only if you use Cruise Control mode. I always argue that Expert mode is the "correct" mode, and in that instance the configuration is far more similar to SnapRAID. It does not take over control of your drives, it does not change any hardware configurations, etc.Pooling in FLEXRAID F does indeed remove the drives. They disappear and only the pool shows up after you install and configure flexriad-f.
I highly recommend using only P19 or older. P20 has been known to cause multiple issues and is difficult to downgrade from. Maybe it'll be fixed if they do a P21.Finally got my IBM M1015 flashed and installed last night using Mfusick's instructions on page 140. Only thing I did different was to get the latest LSI 2118it.bin (P20) from LSI and replaced the one that came prepackaged which is a couple years old. I was unable to flash it with my AsRock Z87 Extreme4 so had to go to a friends house and use one of his older, non-uefi PC's to flash the card. Works great and I really like how the mini-SAS breakout cables cleaned up my bay!
I own both DrivePool and FlexRAID. I currently use FlexRAID for pooling but I have not yet even tested DrivePool. Both have free trial periods, so you can give them both a shot. I will say that FlexRAID pools have some issues with software that doesn't follow proper "etiquette" for opening and writing to files. FlexRAID is very strict in not allowing "proper" usage. I don't know if DrivePool is the same. For the time being, I'm sticking with FlexRAID pooling specifically for the virtual Recycle Bin. DrivePool is a much more "powerful" pooling solution aside from the lack of a virtual Recycle Bin, but I don't know that it's any faster.If I migrate to SnapRaid, is there any difference in overhead or function between FlexRaid or Drivepool? I already own fRaid so I can use that just for drive pooling. If there would be an advantage to DrivePool, I don't mind purchasing it.
