Hi sheepdog users and developers,
I had a presentaion at CloudOpenJapan 2015.
The slide is here:
http://events.linuxfoundation.jp/sites/events/files/slides/COJ2015_Sheepdog_20150604.pdf
This slide introduce some performance results with SSD.
Thanks,
Teruaki

SD_RES_INODE_INVALIDATED response code is used by tgtd and,
previous change broke compatibility with tgtd.
It caused errors when active path was down with using
iSCSI multipath.
This patch reverts a part of previous commit
for SD_RES_INODE_INVALIDATED.

V5:
- Change option from block_size_shift to object_size.
- Change parse type to QEMU_OPT_SIZE.
- Add operation to verify max VDI size for resizing.
- Change to use 4MB object size
To display progress bar for vdi_check, block_size_shift
information is needed.
This patch fixes to display progress bar correctly.

A resizable max VDI size was fixed value, 4TB.
So, when block_size_shift was specified more than 22,
resizing VDI size over 4TB caused error.
This patch enables to calculate a resizable max VDI properly.

Why we max VDI size is 4TB if we have object size more than 4MB? I remember
in the past max size is 4TB because object is 4MB.
Sorry
Previously dog vdi_alter_copy command was failed, because of using
a invalid block_size_shift.
This patch fix to use a right block_size_shift.

Previously, data_length was handled as integer in some places.
But, data_length of a request/response data type is uint32_t,
so there were some bad behaviors.
This patch fixes to handle data_length as uint32_t.

HyperVolume simultaneously.
But, users can create a new VDI with both options, -y and -z,
with dog command.
This patch changes that users can't specify both those options

Qemu backend driver for sheepdog used a hard-coded value
'SD_DATA_OBJ_SIZE' when you created VDI with qemu-img
command.
Then, this patch add operation SD_OP_GET_CLUSTER_DEFAULT
to get a cluster default value of block_size_shift
for creating a VDI.

Data object size was fix to 4MB and not selectable.

block_size_shift bit num to 23.
