Sage,

Thanks for the great work! Could you provide any links describing how to
tune the scrub and snap trim thread pool IO priority? I couldn't find
these settings in the docs.

IIUC, 0.67.11 does not include the proposed changes to address #9487 or
#9503, right?

Thanks,
Mike Dawson

Sage,

the scrub and snap trim thread pool IO priority? I couldn't find these
settings in the docs.

It's

osd disk thread ioprio class = idle
osd disk thread ioprio priority = 0

Note that this is a short-term solution; we eventaully want to send all IO
through the same queue so that we can prioritize things more carefully.
This setting will most likely go away in the future.

IIUC, 0.67.11 does not include the proposed changes to address #9487 or
#9503, right?

Correct. That will come later once it's gone through more testing.

Thanks!

The documentation for these can be found at

Hi Mike,

Sage,

I use:

[osd]
osd disk thread ioprio class = 3
osd disk thread ioprio priority = 0

You’ll need to use the cfq io scheduler for those to have an effect.

FYI, I can make scrubs generally transparent by also adding:

osd scrub sleep = .1
osd scrub chunk max = 5
osd deep scrub stride = 1048576

Your mileage may vary.

IIUC, 0.67.11 does not include the proposed changes to address #9487 or #9503, right?

Those didn’t make it.

Cheers, Dan

Sigh.. it looks like the version that went into master and firefly uses
the string names for classes while the dumpling patch takes the numeric
ID. Oops. You'll need to take some care to adjust this setting when you
upgrade.

Looks like the packages have partially hit the repo, but at least the
following are missing:

Based on the timestamps of the files that made it, it looks like the
process to publish the packages isn't still in process, but rather
failed yesterday.

That is odd. I just went ahead and re-pushed the packages and they are
now showing up.

Thanks for letting us know!
