Description

I found this problem during the investigation on LU-2809. While running "lfs setstripe -c -1 -i n testfile", if ost index n doesn't start from 0, it shows that data can't be striped across all the OSTs and OST0 is always ignored.

• is duplicated by: LU-2893 OST index 0 never used when offset is specified
• is related to: LU-2809 fix ll_setxattr() to always ignore ll_stripe_offset
