Warner, are you OK with the explanation above?

About my note:

In D39867#907602, @imp wrote:

Is it better to fix it here, or where sc->max_targets is set? What's the source of this number, and how did it come to be off by one? And does vmware do it wrong consistently? Or is this nothing more than the 'number of targets' vs 'maximum target because we start at 0' issue other SIMs cope with?

rebase after baseline integration

rebase on D39634

fix uninitialized variable

move baseline file to usr.sbin/tzsetup to not clobber seemingly unrelated share/zoneinfo

• make -d take path to zonetab file, so that baseline target uses the zone1970.tab in src and not from installed system
• update summary to explain why ${SRCTOP}/share/zoneinfo location

I like this idea, but I don't think this should live under /usr/share/zoneinfo. I believe that zoneinfo should *only* contain files generated by tzdata.

Maybe this should live in /usr/share/misc instead?

deduplicate added code

grrrr, sorry, really upload the updated patch

number continent entries consistently with lower-level menus

Has this change been tested?

added IPMI_GET_MSG_DATA_NA for 0x80 magic value

• add sysctl to control the "fps"
• add pnp entries
• add to build

Add naive implementation of scheduled updates.

Sorry, I completely forgot about this review, and now another PR was filed for the same problem. Could you please take another look? (I have updated the test case a bit for more complete switch testing).

update the test case to make it cover all switches between these locales
add the spdx identifier

Apr 16 11:36:45 sun ZFS[45956]: catastrophic pool I/O failure, zpool=data

Now every FS access is stuck. I was able to save the kernel dump using NMI (in case we can get something interesting from it).

This same system works just fine using the same HBA, same disks, same cabling under illumos (using our internal smartpqi driver) transferring TBs worth of data, so I don't expect this to be hardware issue.

HBA is 1100-8i, disks are 4x WDC WD40PURZ SATA3 HDDs, connected using breakout cable.

Thanks for testing the changes, The lockup issue is new to us. Could you please provide the Z-Pool reproduction steps so we can reflect the setup in our lab too for testing.

looking at this again, i'm not sure if the logic should be simply removed and not fixed instead -- i'll file a bug in case someone else would like to fix this properly

not compatible with recent changes

It almost applied cleanly to stable/12 branch, but not to the main branch:

In the main branch, it crashed patch :(.
A quick sample of the .rej files shows the diffs likely are easy to resolve by hand, but with such a large patch I'm leery to do so. Add '-l' to patch to cope with whitespace changes didn't seem to help.
So it looks like this patch needs to be regenerated and/or moved to git where patch generation and uploading is a bit more reliable.

(Also commented on a couple of nits that didn't look quite right in the copyright stuff, but that can wait for the patch to get done).

Hi,

• 12.0 stable branch and 12.2 main branch has two different source codes. I've pulled the 12.0 source code and applied the patch. (12.0 stable branch has bug fixes which is done by community but I do not see the same changes in 12.2 main branch because of that the patch is failing on 12.2 main branch).

"main" mentioned is literally main git branch, where this change should go first (and it's 14.0-CURRENT at the moment). I have HBA 1100-8i that is misbehaving under load, so I'd really like to try this patch -- could you please rebase this against main?

This patch is for 12.2 only, I will push a new patch separately to the main branch.

@yuripv do you have any open issues for the man page?

I would approve it, but you have spend more time in reviewing it.

I'd rather not modify the contrib source, skip installing these, and use MLINKS instead.

some style.mdoc.5 cleanup
