Re: [Dspace-tech] assetstore across multiple partitions
Hi Mark, John F wrote to you on the partitioning question, but I'm the one who posed the question. We are building a dspace installation to upgrade the current which is running on an old box. It is new hardware. The assetstore(s) will me on a Dell MD1000 array. I want to partition the array into 2T partitions with XFS file system to aid in recovery in the event recovery is forced. I don't have a lot experience with recovery times on large partitions, but smaller partitions will recover faster. It sounds like to me you can manually balance data stored on each partition. How can you configure this through dspace.cfg? Any suggestions would be appreciated.Thanks. Kent On Tue, 2008-09-16 at 14:19 -0400, John Furfey wrote: Begin forwarded message: From: Mark H.

You can configure multiple assetstore directories, and they can be on different partitions. Only one is designated to be the place that new submissions go at any particular time.

I don't have a lot experience with recovery times on large partitions, but smaller partitions will recover faster. On the other hand, you'll have more partitions to recover. fsck will try to do them all in parallel, if they all have the same fs_passno in /etc/fstab, but there are limits all along the data path which may constrain the saving you can achieve. I'm not really into high-performance storage so I can't offer specific advice about the potential bottlenecks. It sounds like to me you can manually balance data stored on each partition. How can you configure this through dspace.cfg? This is the section you need to look at: # File Storage ## # Asset (bitstream) store number 0 (zero) assetstore.dir = /first/assetstore # Specify extra asset stores like this, counting from 1 upwards: # assetstore.dir.1 = /second/assetstore # assetstore.dir.2 = /third/assetstore # Specify the number of the store to use for new bitstreams with this property # The default is 0 (zero) which corresponds to the 'assetstore.dir' above # assetstore.incoming = 1 You would mount a bunch of partitions somewhere, configure [assetstore.dir, assetstore.dir.1 ... assetstore.dir.99 or whatever] to point to those mount points, and then from time to time change assetstore.incoming to the number of the assetstore you want new submissions to go into. Each change to assetstore.incoming will require restarting DSpace. DSpace will only fill one assetstore at a time. -- Mark H.
