Placement in different controllers and/or groups of disks

[rogerpinet 0]

Hello,

I'd like to know if it is possible to configure file placement to be able to duplicate files in disks belonging to different controllers (or, in general, in different groups of disks), in order to protect ourselves from controller problems.

I have 14 disks, 7 in one controller and 7 in another one. One of the controllers failed last week and destroyed all the information of its disks… If the files were duplicated with copies on disks pertaining to different controllers, all the information would have been available.

Thanks in advance.

You could create two pools - one for each controller - with no duplication

then make a new pool of the the two pools with duplication - i.e a pool of pools

Thanks for your reply, but how can I do that? A pool does not appear as a candidate to be added to another pool. I don't think that it's possible in Drivepool to create pools of pools...

DP has offered hierachical Pools since rencently, version 2.2.0.744 or so. If you're on an older version you'd need to update. Not sure if there has been a stable release already with this feature. I am running .746 BETA (an early adopter exactly for this feature).

Yes, I've seen that the "pool of pools" feature is available in v2.2 (currently in beta). This will be great and should be a solution to the issue I posted!

Thanks!

Yeah, the public beta (2.2.0.881, as of the time of this post) supports the hierarchical pooling.  And that's what you'd want to do.

Is there any estimated date for the stable version?

"Soon(TM)".

We don't have an ETA, but we hope to have it out very soon.
