[LU-7719] llapi_layout_test to support def.stripe count=-1

• Type: Bug
• Resolution: Low Priority
• Priority: Trivial
• Severity: 3
• Assignee: Alex Zhuravlev
• Reporter: Alex Zhuravlev

Description

at local testing (like sh sanity.sh) sanity/27D fails because default stripe count is set to -1 (STRIPES_PER_OBJ=-1), but llapi_layout_test doesn't expect "undefined" numbers.
