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. Discard checkpoint 34# 8. Verify zdb does not find the checkpoint anymore in the 35# current state. 36# 9. Verify that zdb cannot find the checkpointed state 37# anymore when trying to open it for verification. 38# 39 40verify_runnable "global" 41 42# 43# zdb does this thing where it imports the checkpointed state of the 44# pool under a new pool with a different name, alongside the pool 45# with the current state. The name of this temporary pool is the 46# name of the actual pool with the suffix below appended to it. 47# 48CHECKPOINT_SUFFIX="_CHECKPOINTED_UNIVERSE" 49CHECKPOINTED_FS1=$TESTPOOL$CHECKPOINT_SUFFIX/$TESTFS1 50 51setup_test_pool 52log_onexit cleanup_test_pool 53 54populate_test_pool 55log_must zpool checkpoint $TESTPOOL 56 57test_change_state_after_checkpoint 58 59zdb $TESTPOOL | grep "Checkpointed uberblock found" || \ 60 log_fail "zdb could not find checkpointed uberblock" 61 62zdb -k $TESTPOOL | grep "Checkpointed uberblock found" && \ 63 log_fail "zdb found checkpointed uberblock in checkpointed state" 64 65zdb $TESTPOOL | grep "Dataset $FS1" && \ 66 log_fail "zdb found destroyed dataset in current state" 67 68zdb -k $TESTPOOL | grep "Dataset $CHECKPOINTED_FS1" || \ 69 log_fail "zdb could not find destroyed dataset in checkpoint" 70 71log_must zpool checkpoint -d $TESTPOOL 72 73zdb $TESTPOOL | grep "Checkpointed uberblock found" && \ 74 log_fail "zdb found checkpointed uberblock after discarding " \ 75 "the checkpoint" 76 77zdb -k $TESTPOOL && \ 78 log_fail "zdb opened checkpointed state that was discarded" 79 80log_pass "zdb can analyze checkpointed pools." 81
