Re: [Dspace-tech] assetstore across multiple partitions

2008-09-16 Thread Kent Nasveschuk
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

  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.
  
  
  What do you want to accomplish by doing this?

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.

[Dspace-tech] assetstore across multiple partitions

2008-09-10 Thread John Furfey
Is it possible to split up the assetstore directory across multiple  
partitions?
