[lustre-discuss] Real cases where setstripe is useful

[jeevan.patnaik at wipro.com]

Two Quick questions:

For suppose, there are 4 OSTs (5 OSS), no striping. And the no. of clients are 50.

Will the OSS, picks different OSTs automatically when all the clients starts requesting for storage, and will there be evenly distribution of load?

And on top of that, can this be a good configuration? I must say we are trying to replace Netapps NFS solution with Lustre.

The above example may going to be the real case in our setup, or there may be chance of using more OSTs. Unfortunately, I don't have much technical details of our current configuration as of now, if you ask.

Hi,

I have been reading about using setstripe exclusively for files or directories. I would like to know if it is helpful for a grid jobs.

We are going to use lustre in grid environment in place of NFS. So, at what stage, can I exactly use setstripe?

These jobs would generate files and the creation of those files are not in our control and the size to my knowledge, may not be determined in prior.

So, does it mean that in grid, we could only use the default stripe for all files and directories?
