[s-x86] Re: Anyone used DiskSuite 4.2
Reinhold,
I was hoping for something that will allow me to go to town right away. It's purely a bandwidth issue
For instance, I could get started with the disks on the "server" ie. local to the system vs on the Fibre
arrays, and create metadb, that way, I suppose I do not fragment the disks inside the arrays. I have six
drives on the local system, so I could create eight 10m slices there for the metadb. The balance could be
put into good use by making raw swap partitions on all eight disks. I've 4gig RAM. so, I'm looking for ~8gig.
min swap.
Once the above is done, I could use the "metadb" to create the replicas of metadevice state database as-
metadb <options > slice1 slice2 slice3 ... slicen
? Any disadvantage in creating the database this way, should be they inside the high speed FC storage?
Any special option or hints?
After this, I have the FC disks as a single disk, would like to use the whole disk ( all are same )
say, I use slice 7 and define it end to end, and take, for instance 50 of them ( each ~10g ) to create
a single filesystem. Key cosiderations being performance and ability to create large filesystems, as long
as I can pull out my results after my jobs complete, I do not care for anything else.
Now, what is the best way to create these matadevices? stripped, concat ... further, if I have a metadevice
md10 md20 md30 md40, can I at times make them a single large NFS? How do I do that?
I'm aware, I could do- metainit ... slice1 slice2 slice3 ... slicen to create md10. Could you provide me
a specific examples you have used in your experiences.
A commandline like-
1. create metadb
example ...
2. create metadevice
example ...
3. put a number of metadevices into a single NFS
example ...
4. newfs
example ... ( what device ? )
Thanks once again.
