dqlite detection issues with musl and zfs about raft HOT 10 CLOSED

Thanks @dngray. I believe I know what the issue is and how to fix it. Stay tuned :)

@dngray if you have way to re-build the libraft.so object that is installed on your system and confirm that the patch linked above works, that would be great. Thanks

I'll do that, and let you know if I have any trouble.

Okay, i've tested this and it does seem to work!

The sockets are now correctly created (seccomp.socket and unix.socket).

What kernel version are you running on? I'll try to reproduce and fix this.

from raft.

Kernel is 5.4.34-0-lts, and I'm running Alpine Linux 3.11.6, LXD/LXC 4.1

@freeekanayaka btw, if we can find out what is causing this and produce a patch I'll submit to alpinelinux.org and get it included in a package revision.

Once I nail it down, I'll cut a new release. But you can surely cherry pick the patch and submit it to Alpine.

@dngray please can you run lxd again under strace -f instead of just plain strace? Unfortunately the trace you pasted in github.com/lxc/lxd/issues/7347 includes only the main thread.

Sure I just ran strace -o ~/strace.log -f lxd here's the complete trace strace.2020_05_12_9_15_log.gz

If you need me to do anything else I'm happy to help however best I can. I did format an external disk with EXT4, and mounted it to /var/lib/lxd and that worked, therefore it must be a combination of ZFS and musl.
