Panic on NetBSD-9 using zfs receive and xen
hello. I'm experimenting with a NetBSD-9 Xen server running zfs
volumes as domU disks. While runing a zfs receive of a snapshot of a domU
disk from another server, I experienced the following crash. While this
could be zfs related, I've been running zfs receives numerous times on the
system without a problem. This is on Dom0 with 8GB of RAm and 1 CPU. This
is from NetBSD-9_BETA from about September 25, 2019. I wasn't able to get
a crash dump, but, maybe, this log will help figure out what's going wrong.
It seems like a race condition in the pool code, but I'm not familiar with
that part of the kernel enough to provide a lot of detail at the moment.
has anyone else seen this issue? Is it a known problem or should I
file a bug?
