Description

On ppc64, with lustre version 2.3.58-4chaos (which is 2.3.58, plus LLNL patches, plus a few that we've pulled in for testing), lfs setstripe no longer seems to work on ppc64 clients. I'm not sure at what point in time they stopped working.

Here's the error:

$ lfs setstripe -c 2 testfile
error on ioctl 0x8008669a for 'testfile' (3): Invalid argument

Afterward there is a 0-length file created that has no stripe information, which makes sense if the striping ioctl() failed, but the mknod() succeeded.

I will attach the lustre log from running the above command. It is very verbose; I used "-1" debug level.
