Create a pool and create file in it. 35# 2. Zinject errors and read using dd to log errors to disk. 36# 3. Make sure file name is mentioned in the list of error files. 37# 4. Start error scrub and wait for it finish. 38# 5. Check scrub ran and errors are still reported. 39# 6. Clear corruption and error scrub again. 40# 7. Check scrub ran and errors are cleared. 41# 42 43verify_runnable "global" 44 45function cleanup 46{ 47 zinject -c all 48 rm -f /$TESTPOOL2/$TESTFILE0 49 destroy_pool $TESTPOOL2 50} 51 52log_onexit cleanup 53 54log_assert "Verify error scrub clears the errorlog, if errors no longer exist." 55 56truncate -s $MINVDEVSIZE $TESTDIR/vdev_a 57log_must zpool create -f -O primarycache=none $TESTPOOL2 $TESTDIR/vdev_a 58log_must zfs create $TESTPOOL2/$TESTFS1 59typeset file=/$TESTPOOL2/$TESTFS1/$TESTFILE0 60log_must dd if=/dev/urandom of=$file bs=2M count=10 61 62lastfs="$(zfs list -r $TESTPOOL2 | tail -1 | awk '{print $1}')" 63for i in {1..3}; do 64 log_must zfs snap $lastfs@snap$i 65 log_must zfs clone $lastfs@snap$i $TESTPOOL2/clone$i 66 lastfs="$(zfs list -r $TESTPOOL2/clone$i | tail -1 | awk '{print $1}')" 67done 68 69log_must zinject -t data -e checksum -f 100 -a $file 70dd if=$file of=/dev/null bs=2M count=10 71 72# Important: sync error log to disk 73log_must sync_pool $TESTPOOL2 74 75# Check reported errors 76log_must zpool status -v $TESTPOOL2 77log_must eval "zpool status -v $TESTPOOL2 | \ 78 grep \"Permanent errors have been detected\"" 79log_must eval "zpool status -v | grep '$TESTPOOL2/$TESTFS1/$TESTFILE0'" 80log_must eval "zpool status -v | grep '$TESTPOOL2/$TESTFS1@snap1:/$TESTFILE0'" 81log_must eval "zpool status -v | grep '$TESTPOOL2/clone1/$TESTFILE0'" 82log_must eval "zpool status -v | grep '$TESTPOOL2/clone1@snap2:/$TESTFILE0'" 83log_must eval "zpool status -v | grep '$TESTPOOL2/clone2/$TESTFILE0'" 84log_must eval "zpool status -v | grep '$TESTPOOL2/clone2@snap3:/$TESTFILE0'" 85log_must eval "zpool status -v | grep '$TESTPOOL2/clone3/$TESTFILE0'" 86 87# Check errors are reported if corruption persists 88log_must zpool scrub -e -w $TESTPOOL2 89log_must eval "zpool status -v | grep 'error blocks'" 90log_must zpool status -v $TESTPOOL2 91log_must eval "zpool status -v $TESTPOOL2 | \ 92 grep \"Permanent errors have been detected\"" 93log_must eval "zpool status -v | grep '$TESTPOOL2/$TESTFS1/$TESTFILE0'" 94log_must eval "zpool status -v | grep '$TESTPOOL2/$TESTFS1@snap1:/$TESTFILE0'" 95log_must eval "zpool status -v | grep '$TESTPOOL2/clone1/$TESTFILE0'" 96log_must eval "zpool status -v | grep '$TESTPOOL2/clone1@snap2:/$TESTFILE0'" 97log_must eval "zpool status -v | grep '$TESTPOOL2/clone2/$TESTFILE0'" 98log_must eval "zpool status -v | grep '$TESTPOOL2/clone2@snap3:/$TESTFILE0'" 99log_must eval "zpool status -v | grep '$TESTPOOL2/clone3/$TESTFILE0'" 100 101# Check errors are cleared 102log_must zinject -c all 103log_must zpool scrub -e -w $TESTPOOL2 104log_must zpool status -v $TESTPOOL2 105log_must eval "zpool status -v | grep 'error blocks'" 106log_mustnot eval "zpool status -v | grep '$TESTFILE0'" 107 108 109log_pass "Verify error scrub clears the errorlog, if errors no longer exist." 110
