Events: <none>I have analyzed moac log file and reconstructed the following sequence of events.
First is created volume pvc-fbceb112-8f44-4004-94a8-8c6935218cd0 with size 8.5GB:
Then we create two more pools:
After 6 seconds we publish the first volume (at 12:31:46.853):
After 13s it is unpublished:
After 26 minutes it is destroyed:
Two questions so far:
Add 1. I suspect that the reason why it takes so long is data reset. We unmap/write zeros to all volume blocks. That raises another question of this could be done asynchronously after we reply that the volume has been destroyed. Is there any risk associated with this approach? k8s would hardly create a volume with the same UUID twice so at least that one can be ignored. What about free space reporting - we won't see the free space reclaimed until the async op finishes = nondeterministic - isn't that confusing?
Let's see what happens next.
Request to create another three volumes at once. All with size 5.3GB:
A concern: I can see all create volume requests proceeding in parallel. How can moac guarantee sufficient space on pool and load balancing fairness if it does not serialize volume create requests?
After 40 minutes the volume destruction begins (at 14:04:30.030):
Oct 22 14:05:46.609 error [csi]: CSI deleteVolume failed: Error: Unexpected error in deleteVolume method: TypeError: Cannot read property 'unregisterNexus' of null
at Nexus.unbind (/nix/store/9gybr2hl3nbv4fdddkvca40zylbrm39n-node_moac-0.1.0/lib/node_modules/moac/nexus.js:92:19)
at Nexus.destroy (/nix/store/9gybr2hl3nbv4fdddkvca40zylbrm39n-node_moac-0.1.0/lib/node_modules/moac/nexus.js:219:14)Again, the destruction of volumes took a couple of minutes, but eventually it completed. Looks easy but when looking at log file it is quite a mess because original requests are mixed with retries and delayed replies for the retries.
Final request is here. We create a volume with size 6.5GB:
nothing interesting is in moac's log after that. Further analysis of mayastor and csi logs will follow.

4 years ago I have analyzed other mayastor log files and haven't found anything interesting. Based on the log files it appears as if there were two mayastor volumes that are up and healthy (the same two volumes mentioned at the end of moac log analysis above). Nothing wrong or whatsoever. There isn't even an attempt to unpublish volumes and destroy them. That is something that one would expect when the pods are terminating.
So the only clue of something wrong is the error stack in kernel log and we would need to debug the issue at a system level as likely it will be related to NVME protocol as such. I see that the kernel version is recent enough (5.9) so we cannot say that it might be an old bug in nvme initiator implementation on linux.

4 years ago You can reset the device suing the following command or one like it:
root@ip-172-20-52-180:/sys/class/nvme/nvme2/nvme2c2n1# echo 1 > device/reset_controller
root@ip-172-20-52-180:/sys/class/nvme/nvme2/nvme2c2n1# pwd
/sys/class/nvme/nvme2/nvme2c2n1@briankmatheson Let me summarize what we have discussed elsewhere.
The NVMe timeouts are set enormously high submitted IO that does not return will hang forever. This is a system configuration issue.
As the system is overload, the time it takes to serve any IO for mayastor is almost zero. That is to say if you start 10 jobs, which will spawn 10 processes, and you only have 2 CPUs, the disregarding system processed and kernel threads, we can not serve the IO at all.
Volumes destroyed that have IO's that have been submitted already -- will cause the system to wait for the IO until the end of time, this should be prevented by the finalizers which @blaisedias has validated to work correctly, did you by any chance had something do a --force?
So what can we do?
If we start with (1) the problem should not happen but 2,3,4 should for sure, always be considered.

4 years ago @gila Thanks for the summary.
IMO this ticket should aim to fix (3), that is "reduce insanely high timeout". Long timeout is the immediate root cause of fio pods stuck in terminating state. (2) and (4) are impossible to enforce as those are more recommendations for the users and falls into best practices category. (1) is something that we need but I would rather have a separate ticket for that and treat it as a new feature rather than a bug. So let's keep the ticket open and use it to deliver a fix for setting appropriate nvme timeout on its behalf.

3 years ago We have added the documentation on isolating cpu cores to mayastor gitbook. And we will be able to tweak io_timeout for nvmf targets when this PR is merged: https://github.com/openebs/Mayastor/pull/815 . The ticket will be closed when the PR is merged.
This happens on a cluster in aws set up by kops:
Looking at the log file there seems to be some kind of a problem with destroying the volumes used in the pods. More information about the resources in the cluster:
