John,
The reason your command fails is that you didn't specify a UUID for an ost after the option. However, if you are trying to retrieve the starting ost, then you don't know it ahead of time and can't supply it on the command line. So that option is clearly not working as intended. Plus, the man page does not indicate --ost requires an option, but the error output does (a clear discrepancy). I would suggest filing a bug report.

All,
While working with the lfs getstripe command I came across this. The getstripe --pool works as expected, but getstripe --ost fails. The usage info that gets printed after the fail indicates it should be a valid option. Am I misunderstanding the man page?
