Hi Colin,

> 1. How repeatable is this?  Does it happen to every instance you launch (=
after a variable number of days)?

Unfortunately we are not in the habit of often redeplying our zfs nodes (si=
nce
they provide storage for whole platforms) :( It still happens to the affect=
ed
nodes though:

 bzgrep "nvme1: Missing interrupt" /var/log/messages.0.bz2 ; grep  "nvme1:
Missing interrupt" /var/log/messages
Nov 16 03:04:18 zfs01 kernel: nvme1: Missing interrupt
Nov 16 03:05:19 zfs01 kernel: nvme1: Missing interrupt

bzgrep "nvme1: Missing interrupt" /var/log/messages.0.bz2 ; grep "nvme1:
Missing interrupt" /var/log/messages
Jan 25 04:29:03 volume3 kernel: nvme1: Missing interrupt
Feb  4 04:04:45 volume3 kernel: nvme1: Missing interrupt
Feb 11 04:04:48 volume3 kernel: nvme1: Missing interrupt

Kind of interesting that zfs01 and volume03 have totally different customer=
s,
usage patterns but have a collission of 2 dates :|=20


> 2. Have you tried different instance types?

Yes. This issue is not manifesting itself on an r4.xlarge instance. Same am=
i on
r5.large: problems...

> 3. What sort of disk is this?

We use cloudformation/ansible to deploy these servers, so they are all kind=
 of
identically configured (apart from sizing).  Both instances suffering from =
this
issue are 500GB+ EBS GP2 or IO disks with GPT and a zpool configured onto t=
hem.=20

Please let me know if you would like to receive more information.

Kind regards,

Ruben
