Also both virtio-blk and ahci-hd drivers now report to guest logical and
physical block sizes of underlying storage, that allow guests properly
align partitions and I/Os for best compatibility and performance.
Hi Alexander,
In a previous reply from Peter Grehan, he said that ahci-hd should
already report the correct block size in 10.1. I had some time to try
it out today, but I'm still having issues:
$ zfs create \
-o compression=off \
-o primarycache=metadata \
-o secondarycache=metadata \
-o volblocksize=4096 \
-o refreservation=none \
-V 10G \
zroot/usr/bhyve/test/img
$ geli init -B none -e AES-XTS -K test.key -l 128 -P -s 4096 \
zvol/zroot/usr/bhyve/test/img
$ geli attach -p -k test.key zvol/zroot/usr/bhyve/test/img
[set up device map, grub-bhyve, etc.]
$ bhyve -A -c 1 -H -P -m 256 \
-s 0:0,hostbridge \
-s 1:0,ahci-hd,img.eli \
-s 2:0,ahci-cd,ubuntu-14.10-server-amd64.iso \
-s 31,lpc -l com1,stdio \
test
[boot guest to recovery console]
$ fdisk -l /dev/sda
fdisk: cannot open /dev/sda: Input/output error
And syslog shows a lot of errors accessing sda.
Note that the actual HDD has 512-byte sectors, so perhaps bhyve is
getting the sector size from the hardware and not from geli / ZFS?
