More importantly, we haven't be able to pin down the root cause of this issue. If anyone is able to reproduce this with logs you will be my hero forever! sage

mount.ceph fails to understand AAAA records from SRV record

#47300 IPv6 addresses are enclosed in square brackets [ipv6addr]:port. Adapting from Ipv4 to 6 without taking the brackets in account (while parsing the address) is a common starting point for bugs :)

The reported failure:

server name not found: 2001:db8:2000:8a:ec4:7aff:fe31:d638:6789 (Name or service not known)

Building on top of #46062. ASan is enabled by defult in Crimson, which resulted in the InitModule leak. When compiling with ASan both crimson and classic report this leak. This leak seems to be intentional and can be suppressed.

Introduction

This directory contains examples on how to use Lua Scripting together with a NATS Lua client to add NATS to the list of bucket notifications endpoints.

NATS

To test your setup:

• Install NATS and start a nats-server.

• Subscribe to the NATS server using go-nats-examples repo, choosing the topic to be 'Bucket_Notification' (as defined in the script)
