Revision 1.2, Mon Nov 10 01:29:28 2003 UTC (13 years, 11 months ago) by fsgqa
Branch: MAIN
Changes since 1.1: +27 -11 lines

Make out of space test more general so I can try different scenarios more easily; add 083 into the auto group.

#! /bin/sh
# XFS QA Test No. 083
#
# Exercise filesystem full behaviour - run numerous fsstress
# processes in write mode on a small filesystem.  NB: delayed
# allocate flushing is quite deadlock prone at the filesystem
# full boundary due to the fact that we will retry allocation
# several times after flushing, before giving back ENOSPC.
