Options I considered where: - grep -v or otherwise filter out those lines - check the failure I am happy to switch to the grep. > > +_check_btrfs_filesystem $SCRATCH_DEV > > +_scratch_mount > > +fssum_post=$($FSSUM_PROG -A $SCRATCH_MNT) > > +[ "$fssum_pre" == "$fssum_post" ] \ > > + || echo "fssum $fssum_pre does not match $fssum_post after enabling squota" > > + > > +# do some more stuff > > +run_check $FSSTRESS_PROG -d $d2 -w -n 2000 $FSSTRESS_AVOID > > +fssum_pre=$($FSSUM_PROG -A $SCRATCH_MNT) > > +_scratch_unmount > > +_check_btrfs_filesystem $SCRATCH_DEV > > + > > +$BTRFS_TUNE_PROG --remove-simple-quota $SCRATCH_DEV >> $seqres.full 2>&1 || \ > > + _fail "remove simple quota failed" > > Same here. > > With that fixed (if it can be done): I think here, the command does generally work how we want: silent on success, spews on failure, but I wanted it to be consistent with the enable, not have to look in different files (or stick in a tee) etc..
