Hello!
I have created "Compression VBDEV" on top of Malloc0 BDEV.
$ sudo /data/devadm/spdk/scripts/rpc.py bdev_compress_create -p ./pmem_files -b
"CryMalloc0A"
COMP_CryMalloc0A
$sudo /data/devadm/spdk/scripts/rpc.py vhost_scsi_controller_add_target vhost.0 0
COMP_CryMalloc0A
0
When I try to execute "mkfs /dev/sda" (where /dev/sda is the COMP_Malloc0 ) in
the inner VM I got error on the VHOST's output:
[2021-09-13 11:32:51.759692] vbdev_compress.c: 811:_comp_bdev_io_submit: *ERROR*: Unknown
I/O type 4
[2021-09-13 11:32:51.759741] vbdev_compress.c: 822:_comp_bdev_io_submit: *ERROR*: on
bdev_io submission!
...
Is there what I'm need to check ?
Thanks in advance!
10:42 a.m.
I/O type 4 is SPDK_BDEV_IO_TYPE_FLUSH
Looks like Compress vbdev does not support this I/O type

I can’t remember off the top of my head why that’s not supported, Jim may recall. I’ll
look through the code today and jog my memory though

Hello!
Do I'm need to check something in the SPDK (may be configuration option for build?) ?
Or this is a problem inspired by the VM's?

It’s listed in a block of other non-RW bdev IO types as TODO. I believe at the time it
was just a matter of priorities. We’d need change the reporting of supported types to
match the underlying device, update the reduce lib to allow the bdev module to determine
which blocks are associated with the incoming range and then just plumb the flush.
I may be missing something (Jim feel free to jump in). Is this something you might be
interested in working on?
Thx

Or add a new spdk_reduce_vol_flush() API. Then the reduce library can drive the flush
operations just like it does for readv/writev.
We also need support for RESET operation.

Hello!
At this nanosecond I'm not sure about of necessity of this feature in my local
project. May be in a near future ...
Thanks to all for the support and explanation!
Sincerely yours, Russian/Ruslan. :-)

Hi Rusian,
As it turns out Monica on the team here in AZ is interested in working on this… look for
it over the coming weeks ☺
Thanks
