Hello everyone!
I'm new here trying to do as much research as I can before purchase. I'm liking all the information I've seen on the main site,manual, and the forums/old forums. I think I've caught a little information off Reddit to push me here. I'm hoping for loads of information and maybe this will help MANY people in the long run on what to do.
So first off on the topic string. I would like to use StableBit's products only. So in doing so I gathered some can's and can not's. That the Drivepool with Scanner are a pair made to secure any deal. But I'm also worried about parity.
My current pool is:
5x4TB Seagates
2x3TB Seagates
The purpose of my pool is family movies / music and pictures. Besides the music and pictures being of small size, the movies range from 400MB-16GB.
Here's some Reddit research that even put me on the research run about StableBit products.

So Drivepool and Drive Bender do not offer parity if a 3rd drive is used, it is simply a pooled hard drive tool?
Also I understand that you will only loose the data on that drive, but is there a way to specify which data should be stored were?

They're wrong. Drivepool offers redundancy via its duplication feature.

Not sure but the creator of drivepool has a vlog on YouTube he explains a lot. Also, the fact that they are so transparent and fairly young suggests many improvements are coming. Regardless if flexraid is better now I am betting on drivepool in the long run. Every purchase helps them develop too!

agree with
im a long time drivepool user (for reference). current setup is > 30TB.
with drivepool you can set a folder (or subfolders) to be duplicated 1-2 times across the pool. 1x duplication will protect against (at max) 1 drive failure; 2x duplication will protect against 2 drives failing (at once). you wont see the duplicated files, but they will be there (if you really need to see them, you can disconnect each drive and hunt for duplicate files).

Just a note that in Drivepool "1x" means no duplication, "2x" means duplication and "3x" means triplication etc but absolutely, you can have as many copies as you have drives in the pool if you are paranoid and have something you would hate to lose.
I have 3x for the family photos as well as a backup online.
Ok in this I was told that :
1. Drivepool offers redundancy via duplication
2. Creator of StableBit products has a Youtube vLog channel (Couldn't find it but found Stablebit.com's and only had two videos no vLogs)
3. One user that spoke so highly of StableBit products (Has owned it for 4-5 years now)
4. Drivepools duplication works via client setting the folders or subfolders. To be duplicated 2x,x3 so on.
I was confused on the duplication settings. And if there is a parity for at least one HDD failure or more depending on settings. I really love the way these products looks, the active community and the progressiveness of the Covecube staff for their products! I need to really strongly put it out here that I would really rather use StableBit's products less programs running and wouldn't have to worry about which one is or isn't causing problems.
This is a two part thread so this is the end of the first research part.
-----------------------------------------------------------------------------------------------------------------------------------------------------------------------
Now for the second part of the researching. I've seen this in a few places doing a StableBit Drivepool for pooling the drives with FlexRaid (Raid-F) for the parity set up. But mostly using all the programs from StableBit where as setting and forgetting "almost" the FlexRaid setup. Here's the research I've dug up well what I could. Oddly I found a couple hints on the Flexraid forums but nothing saying where it was on the forums or what to search for or anything. So most of it was on the old Covecube forums that are read only. I would put links but I think I'll just select the little information I need so this thread doesn't get kicked.
I would think this would work fine, since DP doesn't require the use of drive letters. Removing the drive that way, without waiting for files to be moved off should be quick too. Between DP folder duplication, and FlexRAID DRU protection of the other folders on the drive, you have lost NOTHING. Duplication should rebuild it's files, and the remaining folder contents from that drive will be restored from FlexRAID.
Remember, you can direct FlexRAID to restore a DRU to another destination if you wish, such as a "reserved" empty share you have for this purpose or even a drive outside the pool. If a share in the pool, then "move" the folders there to your proper shares, which will not really physically move anything, just update links to those folders/files. Or just restore to \\Shares and let DP place the files back on the drives in your pool.
I run FlexRAID on my WHS V1 system. I have never had to do a restore, but this is how I would basically manage a drive failure. I use a combination of folder duplication for some shares (photos) and snapshot raid for my other shares with each drive as a DRU + 1 PPU. 9 Drives total, 18TB
I am planning to move to WHS 2011 this week and will be utilizing Stablebit DP for pooling and folder duplication along with FlexRAID as you guys are.
Thanks for all the great information on your experiences with this setup. Admittedly, I don't know much about FlexRAID, but I'm curious to the benefit of running both DP and FlexRAID on the same system. Aren't the two similiar to each other? I looked at FlexRAID a while back before deicding on DrivePoll, but am I missing something with not running both on my WHS2011? Your advice is appreciated. Running FR along side DP has the benefit that you dont need to run duplication on your Media data which would cause a lost of space. FR does also have a pooling feature but its not as stable as DP, but its Raid feature helps cover from drive failure without compromising DP functionality Does that mean you use the pooling of DP and the data protection of FR? I might have to look into that so that I won't have to duplicate over 4TB of visual media. Interesting thought. Are there any basic tutorials out there on how to set up FR with DP already installed? Also, does FR need a dedicated drive for the raid? FR requires you to sacrifice at least 1 disks to be use as a parity drive that will be as big as the biggest single drive in your system. This prarity drive will not be part of your pool since you dont want to have any other data on it besides FR parity data. The amount of parity drives will depend on how much protection you want , the more you have the more you can survive multiple drive failures at once. I only have 1 parity drive because its rare to have 2 drives die exactly at the same time.Check the FR website to learn how FR works, all you need to know really for using both in the same setup, is Dont make your parity drive part of the DP pool and that your protection is dont on each drive individually and not on the pool drive itself. You can also check this forum, i have posted a few screenshots of my setup which could help you understand the setup a bit better Gotcha. I have a new 3TB drive coming in today and I think I'm going to use that for my parity drive then.
Thanks for your help. I know some of the questions are on the FR site, so thanks for getting back to me. np and good luck Hi saitoh183,
I was looking at documentation to set up my first parity drive and I think I'm a bit confused. it looks like the guide located here would be what I want since I don't plan on using FR for pooling:http://wiki.flexraid.com/2011/08/29/setting-up-your-snapshot-raid/
The other write up goes through setting up a pool and then doing your raid. The question I have is about where I set up DRUs and PPUs. Since I'm not using FR for pooling does that mean no DRUs? Or is that where I put the amount of discs I am using in my DP pool? And then possibly extra since I plan on adding more drives at a later date. I'm guessing all of that can be changed later though.
This sounds great, but I will need to keep on reading to see what I need to do. I browsed for you of your screenshots, but only came up with the one from this topic and I didn't notice the FR interface in it. Have a look here http://forum.covecube.com/discussion/554/parity-drive#Item_4DRU/PPu applies to the raid setup and not the pooling so you will want to use the advanced setup and not the Cruise control (Raid-F +Pooling). If i take my setup as an example:I have 1X2TB as PPU and 6 DRUsUnder 1 DRU i have 6 drives which total 2TBUnder each other DRU, I have 1X2TB and 1 DRU with 1x1TBif you compare this to a traditional Raid 5, each DRU = 1 drive in a Raid 5 setup so my DRU with 6 drives under it is considered as 1 failure even if multiple drives fail in that DRU but it would be 2 failures if that DRU failed + 1 of my DRUs that contains only 1x2TB drive. So PPU would recover only 1 DRU regarless of the amount of drives under that single DRU but would only be able to recover 1 DRU if 2 separate DRUs failed.For Expansion i suggest using the Raid Tx engine because this will allow for the best expansion as the other modes are limited to a certain number of PPUs and DRUs. http://wiki.flexraid.com/about/1355-2/Your link in your post is the right one to setup your raid. You are also not obligated to put a entire drive as DRU, you can also put just a folder.. Like for my PPU i put L:\PPU. For my DRU,s, since all my drives are in the DP pool, i put the entire drive instead of just the PD hidden poolpart folder incase 1 day somehappens or i need to recreate the pool, the poolpart folder might not have the same exact name which would force me to recreate the raid from scratch. Also before creating the raid, i would suggest mapping your drive to NTFS folders like i show above so that you wont have to recreate your raid down the line.
And the second part.
Hi,Just wondering if there's any plans to add any RAID5 like features in DrivePool. Being able to swap a failing drive and not having to worry about copying / losing data would be a big plus for me.If there's no plans to add this in DrivePool, does anybody know if something like FlexRAID will play nicely with DrivePool? Thanks!-Dan I don't think DP will ever have Raid capability because it already has duplication(file and folder) in place. As for if plays nice with Flexraid, yes it does. I have been running both for more then a year now and have never had an issue. Since i use Flexraid, i have no use for duplication. If you do decide to go this route and also add Stablebit scanner, just remember to configure your Flexraid schedule to not conflict with scannerThis image has been resized to fit in the page. Click to enlarge. MemberHi saitoh183,How does this work exactly then? I'm assuming I set up FlexRAID first, with my DRUs and one or more PPUs, then add the DRUs to the DrivePool pool. Does that sound right? Also, does read/write performance take a hit when compared to using just DrivePool? Thanks very much for your replies!-Dan It doesn't matter in which order you set them up. DP just merges your drives, Your performance comes from DP and Flexraid doesn't affect it. Flexraid is only relevant for performance if you were using the pooling feature of it. Since you aren't, the only performance you will see is when your parity drive is being updated. Also dont forget to not add your PPU to the pool
Ok I read the information on the first thread above and that it talking about how it was possible. Saitoh183 posted a few times on that thread with more information on Drivepooling and Flexraiding. Goes through making sure everyone knows that you lose one or more drives (largest or equal size of a every drive"Not put together") for a parity disk or a PPU so called.
In the second quote of research it is a small thread "explaining" how to setup the both of them. I know and understand that Saitoh183 said "It doesn't matter in which order you set them up. DP just merges your drives, Your performance comes from DP and Flexraid doesn't affect it. Flexraid is only relevant for performance if you were using the pooling feature of it. Since you aren't, the only performance you will see is when your parity drive is being updated. Also dont forget to not add your PPU to the pool"
I know from what Saitoh183 it doesn't matter. But I figured you would make the StableBit Drivepool setup the drive letter.
Now going to the FlexRaid:
1. Add new configuration
2. Name Cruise Control with Snapshot and Create
3. Open the new configuration to edit and open Drive Manager
4. Add the DRU's (Data drives) and one or more PPU for parity backup's (Snapshots) I've read a few setup guides and I've heard 1 PPU drive for every 6 and I've heard 1 PPU drive for every 10 both are fine.
5. Initialize the raid if data is on the DRU's it will now do a parity snapshot, now back to the home page for the named configuration and Start Storage Pool.
Not sure what else to after that if it's even right. I don't think the FlexRaid should have a drive letter or it would make things more confusing than it already is using two programs.
Please enlighten my with any information that can help this research that will help with my purchase and hopefully more people that decide to do this setup also. I would like to firstly so I appreciate everyone up front for there past help with others to even get me here with this information! Thanks again.
