Hi, I'm reading the source code of generic/044 in xfstests, and I cannot figure out the difference compared with 043 testcase: ------------------------------------------------------------------------------- $ diff -Nu 043 044 --- 043 2015-03-09 10:03:48.013887582 +0800 +++ 044 2015-03-09 10:03:48.013887582 +0800 @@ -1,5 +1,5 @@ #! /bin/bash -# FSQA Test No. 043 +# FSQA Test No. 044 # # Test for NULL files problem # @@ -56,6 +56,12 @@ echo error creating/writing file $file exit fi + xfs_io -c "truncate 64k" $file > /dev/null + if [ $? -ne 0 ] + then + echo error truncating file $file + exit + fi let i=$i+1 done But before the 'truncate 64K', only 64K sized files are created: xfs_io -f -c "pwrite -b 64k -S 0xff 0 64k" $file > /dev/null So I think it's useless here, or some typo e.g smaller truncate needed?
