Subject: [PATCH] test/osd/osd-dup.sh: warn on low open file limit
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

This test fails badly when open file limit is low. Increasing to around
1536 seems to be doing the trick, so warn the user with appropriate
message and try to proceed anyway.
