Description

Steps to Repro
1. Run the following longevity script on 6.6.3 for 5 days.

./sequoia -client 172.23.104.254:2375 -provider file:centos_second_cluster.yml -test tests/integration/test_allFeatures_madhatter_durability.yml -scope tests/integration/scope_Xattrs_Madhatter.yml -scale 3 -repeat 0 -log_level 0 -version 6.6.3-9808 -skip_setup=true -skip_test=false -skip_teardown=true -skip_cleanup=false -continue=false -collect_on_error=false -stop_on_error=false -duration=604800 -show_topology=true

At this point it should have a 27 node cluster ( 9 Kv, 6 Index, 3 analytics, 3 fts, 3 eventing and 3 n1ql)
2. Create 10k metakv tombstones. This has been part of our testing since ~~MB-44838~~ was fixed. We used to have a total of around 25k for CC, have reduced it here to around 12k.

 #!/bin/sh

for i in {0..10000}

do

        `curl -X PUT -u Administrator:password http://localhost:8091/_metakv/key{$i} -d 'value=foo1'`

        `curl -X DELETE -v -u Administrator:password http://localhost:8091/_metakv/key{$i}`

    done

3. Swap rebalance 6 nodes , 1 of each service with that of 7.0.2 nodes. Rebalance goes through successfully.
4. Failover 6 nodes(6.6.3 nodes)1 of each service(kv is graceful failover), Upgrade these nodes to 7.0.2, do a recovery of all the 6 node(kv is delta recovery) and rebalance.
5. Repeat step no 4 until all the nodes in cluster are upgraded to 7.0.2.

After upgrade I validated that all the metakv tombstones are purged and enabled IPv4 only + enforce tls using the below commands.

At this point I noticed that Rebalance button was enabled. Not sure why this was enabled as we had nothing to rebalance afaik(this is tracked through ~~MB-48448~~). However, when I did rebalance it failed as shown below.

Description

+Steps to Repro+
1. Run the following longevity script on 6.6.3 for 5 days.
{noformat}
./sequoia -client 172.23.104.254:2375 -provider file:centos_second_cluster.yml -test tests/integration/test_allFeatures_madhatter_durability.yml -scope tests/integration/scope_Xattrs_Madhatter.yml -scale 3 -repeat 0 -log_level 0 -version 6.6.3-9808 -skip_setup=true -skip_test=false -skip_teardown=true -skip_cleanup=false -continue=false -collect_on_error=false -stop_on_error=false -duration=604800 -show_topology=true
{noformat}
At this point it should have a 27 node cluster ( 9 Kv, 6 Index, 3 analytics, 3 fts, 3 eventing and 3 n1ql)
2. Create 10k metakv tombstones. This has been part of our testing since ~~MB-44838~~ was fixed. We used to have a total of around 25k for CC, have reduced it here to around 12k.
{noformat}
#!/bin/sh
for i in {0..10000}
    do
        `curl -X PUT -u Administrator:password http://localhost:8091/_metakv/key{$i} -d 'value=foo1'`
        `curl -X DELETE -v -u Administrator:password http://localhost:8091/_metakv/key{$i}`
    done
{noformat}
3. Swap rebalance 6 nodes , 1 of each service with that of 7.0.2 nodes. Rebalance goes through successfully.
4. Failover 6 nodes(6.6.3 nodes)1 of each service(kv is graceful failover), Upgrade these nodes to 7.0.2, do a recovery of all the 6 node(kv is delta recovery) and rebalance.
5. Repeat step no 4, until all the nodes in cluster are upgrade.

After upgrade I validated that all the metakv tombstones are purged and enabled IPv4 only + enforce tls using the below commands.

At this point I noticed that Rebalance button was enabled. Not sure why this was enabled as we had nothing to rebalance afaik(this is tracked through ~~MB-48448~~). However, when I did rebalance it failed as shown below.

Description

+Steps to Repro+
1. Run the following longevity script on 6.6.3 for 5 days.
{noformat}
./sequoia -client 172.23.104.254:2375 -provider file:centos_second_cluster.yml -test tests/integration/test_allFeatures_madhatter_durability.yml -scope tests/integration/scope_Xattrs_Madhatter.yml -scale 3 -repeat 0 -log_level 0 -version 6.6.3-9808 -skip_setup=true -skip_test=false -skip_teardown=true -skip_cleanup=false -continue=false -collect_on_error=false -stop_on_error=false -duration=604800 -show_topology=true
{noformat}
At this point it should have a 27 node cluster ( 9 Kv, 6 Index, 3 analytics, 3 fts, 3 eventing and 3 n1ql)
2. Create 10k metakv tombstones. This has been part of our testing since ~~MB-44838~~ was fixed. We used to have a total of around 25k for CC, have reduced it here to around 12k.
{noformat}
#!/bin/sh
for i in {0..10000}
    do
        `curl -X PUT -u Administrator:password http://localhost:8091/_metakv/key{$i} -d 'value=foo1'`
        `curl -X DELETE -v -u Administrator:password http://localhost:8091/_metakv/key{$i}`
    done
{noformat}
3. Swap rebalance 6 nodes , 1 of each service with that of 7.0.2 nodes. Rebalance goes through successfully.
4. Failover 6 nodes(6.6.3 nodes)1 of each service(kv is graceful failover), Upgrade these nodes to 7.0.2, do a recovery of all the 6 node(kv is delta recovery) and rebalance.
5. Repeat step no 4, until all the nodes in cluster are upgrade.

After upgrade I validated that all the metakv tombstones are purged and enabled IPv4 only + enforce tls using the below commands.

From the above logs, it appears like gocb calls to read (and subsequently update) checkPoint data from KV are failing continuously. That sort of explains why rebalance is not proceeding further. Eventing needs to update checkpoint data during rebalance. Requesting Ankit Prabhu to take a deeper look.

Summary

[System Test] - Eventing rebalance hangs post 6.6.3 -> 7.0.2 upgrade

[System Test] - Eventing rebalance fails after 1200secs consistently post enforce-tls unless functions are paused/resumed

This issue is not specific to upgrade, but a known issue/limitation with turning on 'enforce-tls' when >=1 eventing functions are in 'deployed' state. It was agreed upon during design phase that users will have to pause their eventing functions prior to changing their encryption configuration and resume them after. The same is captured at https://issues.couchbase.com/browse/MB-47707?focusedCommentId=534961&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-534961. And at https://issues.couchbase.com/browse/MB-47707?focusedCommentId=535066&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-535066.

We have also raised a documentation ticket to track the same https://issues.couchbase.com/browse/DOC-9146.

And we have an existing Neo ticket https://issues.couchbase.com/browse/MB-48334 which was logged earlier to track fixing this limitation. Hence resolving this MB duplicate.

However, we are now thinking if this limitation is going to annoy our customers & bite us back in the form of a CBSE in future. So currently exploring ways to fix this with minimal changes to stay true to our "Always On" claim. Thank you!

Could you please confirm if below works post upgrade?
1. Pause the functions
2. Change encryption level
3. Resume functions
4. Rebalance
Expectation is that above should work.
