Create pool 27# 2. Populate it 28# 3. Take checkpoint 29# 4. Modify data (include at least one destructive change) 30# 5. Verify zdb finds checkpoint when run on current state 31# 6. Verify zdb finds old dataset when run on checkpointed 32# state 33# 7. Export pool, and verify the same things with zdb to 34# test the -e option. 35# 8. Import pool and discard checkpoint 36# 9. Verify zdb does not find the checkpoint anymore in the 37# current state. 38# 10.Verify that zdb cannot find the checkpointed state 39# anymore when trying to open it for verification. 40# 41 42verify_runnable "global" 43 44# 45# zdb does this thing where it imports the checkpointed state of the 46# pool under a new pool with a different name, alongside the pool 47# with the current state. The name of this temporary pool is the 48# name of the actual pool with the suffix below appended to it. 49# 50CHECKPOINT_SUFFIX="_CHECKPOINTED_UNIVERSE" 51CHECKPOINTED_FS1=$TESTPOOL$CHECKPOINT_SUFFIX/$TESTFS1 52 53setup_test_pool 54log_onexit cleanup_test_pool 55 56populate_test_pool 57log_must zpool checkpoint $TESTPOOL 58 59test_change_state_after_checkpoint 60 61zdb $TESTPOOL | grep "Checkpointed uberblock found" || \ 62 log_fail "zdb could not find checkpointed uberblock" 63 64zdb -k $TESTPOOL | grep "Checkpointed uberblock found" && \ 65 log_fail "zdb found checkpointed uberblock in checkpointed state" 66 67zdb $TESTPOOL | grep "Dataset $FS1" && \ 68 log_fail "zdb found destroyed dataset in current state" 69 70zdb -k $TESTPOOL | grep "Dataset $CHECKPOINTED_FS1" || \ 71 log_fail "zdb could not find destroyed dataset in checkpoint" 72 73log_must zpool export $TESTPOOL 74 75zdb -e $TESTPOOL | grep "Checkpointed uberblock found" || \ 76 log_fail "zdb could not find checkpointed uberblock" 77 78zdb -k -e $TESTPOOL | grep "Checkpointed uberblock found" && \ 79 log_fail "zdb found checkpointed uberblock in checkpointed state" 80 81zdb -e $TESTPOOL | grep "Dataset $FS1" && \ 82 log_fail "zdb found destroyed dataset in current state" 83 84zdb -k -e $TESTPOOL | grep "Dataset $CHECKPOINTED_FS1" || \ 85 log_fail "zdb could not find destroyed dataset in checkpoint" 86 87log_must zpool import $TESTPOOL 88 89log_must zpool checkpoint -d $TESTPOOL 90 91zdb $TESTPOOL | grep "Checkpointed uberblock found" && \ 92 log_fail "zdb found checkpointed uberblock after discarding " \ 93 "the checkpoint" 94 95zdb -k $TESTPOOL && \ 96 log_fail "zdb opened checkpointed state that was discarded" 97 98log_pass "zdb can analyze checkpointed pools." 99
