[Lustre-discuss] What stripe size and extent size to choose for Lustre

[Jagga Soorma]

Hi Guys,

I am new to Lustre and will be deploying a small 20 node cluster using the
Lustre FS.  I do not have many requirements from my users :( and not sure
what type of workload they will be putting on this filesystem.  All nodes
will be interconnected using Infiniband.  My question is what stripe size
and extent size to use for my environment:

Stripe Size: I was thinking of just setting this to -1 since I will be
adding more OSS's at a later time and will probably have 4-5 OST's per OSS.
Any downfalls of using -1?
Extent Size: I was thinking of setting this to 1MB.

Regards,
-Simran
