I'm fine with either way since it's a simple functionality test, yet for most common cases, stratch devices are somewhat large. I tend to use a relative controllable small value. Actually, this case was from xfs/127 with some modification. > > > +_scratch_mkfs -dsize=$size -dagcount=3 2>&1 | \ > > + tee -a $seqres.full | _filter_mkfs 2>$tmp.mkfs > > +. $tmp.mkfs > > +_scratch_mount >> $seqres.full 2>&1 > > + > > +echo "Shrink fs (small size)" > > +$XFS_GROWFS_PROG -D $((dblocks-512*1024/dbsize)) $SCRATCH_MNT \ > > + >> $seqres.full 2>&1 || echo failure > > +_scratch_cycle_mount > > I don't understand the XFS Shrink new feature that much, is the "cycle_mount" > necessary?

It seems that ./check will fsck scratch device as well. Will update it. Thanks, Gao Xiang
