Re: [Libguestfs] [zfs-discuss] ZFS-on-NBD
just a few comments
+ using S3 as a block device will always suffer from the fact that it really isn’t a block
device… hiding it behind any other block device interface won’t really help except in very
constrained cases (basically, what you proved again)
+ ZFS aggregates writes, which further complicates fake block device interfaces
+ there is a dev effort to come up with an object-based vdev type, but I’m not aware of
its current status
+ L2ARC is definitely not a write-through cache
