Hi everyone,

While setting up automated testing for PVE9 we noticed that scsi block
devices were missing several udev properties.

After a bit of digging, the root cause turns out to be a regression in
the sg_inq tool (from sg3_utils). This bug slipped in as part of some
refactoring related to json output formatting on Feb 7, 2023.

I filed an issue upstream -- check it out for more details:
https://github.com/doug-gilbert/sg3_utils/issues/63

I also submitted a pull request which fixes the issue:
https://github.com/doug-gilbert/sg3_utils/pull/64

The likelihood of a new upstream release coming in time for the PVE9
release seems quite low. Perhaps a local patch for sg3_utils is in
order?

Take care,
Josh

and while the fix didn't make it into Trixie itself, it's at least
called out in the release notes as an issue to be aware of:

FYI: We just uploaded a build of sg3-utils with your patch included
into the pve-test trixie repo, it's version 1.48-2+pmx1.

I could easily reproduce the issue here and thus test the patch.

E.g., the output of `sq_inq --export` with the original version:

sg_inq --export /dev/sg5
SCSI_TPGS=0
SCSI_TYPE=medium changer
SCSI_VENDOR=QUANTUM
SCSI_VENDOR_ENC=QUANTUM\x20

And after upgrading to the newer version with your patch:

sg_inq --export /dev/sg5
SCSI_TPGS=0
SCSI_TYPE=medium changer
SCSI_VENDOR=QUANTUM
SCSI_VENDOR_ENC=QUANTUM\x20
SCSI_MODEL=UHDL
SCSI_MODEL_ENC=UHDL\x20\x20\x20\x20\x20\x20\x20\x20\x20\x20\x20\x20
SCSI_REVISION=0096

Thanks!
 Thomas

Hi Thomas,

Fantastic!

Thanks for creating a Debian bug & cherry-picked MR. Fingers crossed
the changes flow through into PVE9. :)

Take care,
Josh

Thanks again for the heads up, as mentioned in the forum I also
created a Debian bug report:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1109923

And created a merge request with a cherry-pick of this patch
on the Debian package:
https://salsa.debian.org/linux-blocks-team/sg3-utils/-/merge_requests/10

Yeah, we will take a closer look and pick the fix up for our repos
if nothing comes up.

Thanks!
