Create pool # 2. Populate it # 3. Take checkpoint # 4. Modify data (include at least one destructive change) # 5. Verify zdb finds checkpoint when run on current state # 6. Verify zdb finds old dataset when run on checkpointed # state # 7. Export pool, and verify the same things with zdb to # test the -e option. # 8. Import pool and discard checkpoint # 9. Verify zdb does not find the checkpoint anymore in the # current state. # 10.Verify that zdb cannot find the checkpointed state # anymore when trying to open it for verification. # verify_runnable "global" # # zdb does this thing where it imports the checkpointed state of the # pool under a new pool with a different name, alongside the pool # with the current state. The name of this temporary pool is the # name of the actual pool with the suffix below appended to it. # CHECKPOINT_SUFFIX="_CHECKPOINTED_UNIVERSE" CHECKPOINTED_FS1=$TESTPOOL$CHECKPOINT_SUFFIX/$TESTFS1 setup_test_pool log_onexit cleanup_test_pool populate_test_pool log_must zpool checkpoint $TESTPOOL test_change_state_after_checkpoint zdb $TESTPOOL | grep "Checkpointed uberblock found" || \ log_fail "zdb could not find checkpointed uberblock" zdb -k $TESTPOOL | grep "Checkpointed uberblock found" && \ log_fail "zdb found checkpointed uberblock in checkpointed state" zdb $TESTPOOL | grep "Dataset $FS1" && \ log_fail "zdb found destroyed dataset in current state" zdb -k $TESTPOOL | grep "Dataset $CHECKPOINTED_FS1" || \ log_fail "zdb could not find destroyed dataset in checkpoint" log_must zpool export $TESTPOOL zdb -e $TESTPOOL | grep "Checkpointed uberblock found" || \ log_fail "zdb could not find checkpointed uberblock" zdb -k -e $TESTPOOL | grep "Checkpointed uberblock found" && \ log_fail "zdb found checkpointed uberblock in checkpointed state" zdb -e $TESTPOOL | grep "Dataset $FS1" && \ log_fail "zdb found destroyed dataset in current state" zdb -k -e $TESTPOOL | grep "Dataset $CHECKPOINTED_FS1" || \ log_fail "zdb could not find destroyed dataset in checkpoint" log_must zpool import $TESTPOOL log_must zpool checkpoint -d $TESTPOOL zdb $TESTPOOL | grep "Checkpointed uberblock found" && \ log_fail "zdb found checkpointed uberblock after discarding " \ "the checkpoint" zdb -k $TESTPOOL && \ log_fail "zdb opened checkpointed state that was discarded" log_pass "zdb can analyze checkpointed pools."
