[Drbd-dev] crm_attribute --quiet (was Fwd: [Linux-HA] Should This Worry Me?)

[Florian Haas]

Lars/Andrew,

While Eric is evidently on a DRBD version whose ocf:linbit:drbd does not
invoke crm_attribute with the flag to suppress logging, I'm mildly
confused as to what the correct flag actually is. ocf:linbit:drbd (in
both 8.3 and 8.4) uses "-Q" whereas Pacemaker expects "-q" as of this
commit:

commit c11ce5e9b0b13ead02b5fc4add928d7e7f95092e
Author: Andrew Beekhof <andrew@beekhof.net>
Date:   Tue Sep 22 17:29:38 2009 +0200

    Medium: Tools: Use -q as the short form for --quiet (for consistency)

    Mercurial revision: 7289e661e4923beee4b7b45bc85592564ccdc438

Should ocf:linbit:drbd be using "-q"?

Cheers,
Florian

Should I be concerned that the standby node of a 2-node cluster is
logging these messages about every 15 seconds? This cluster has been up
and running apparently fine for a year.

FYI, this particular cluster is running DRBD 8.3.2.

Right, and this changeset:

commit e71e95975f2c4231a240ad856a5ac37d65685061
Author: Florian Haas <florian.haas@linbit.com>
Date:   Fri Sep 18 15:18:31 2009 +0200

    OCF RA: use crm_master in quiet mode in set_master_score()

... was committed during the 8.3.3 development cycle. So the fact that
you are getting this message (which is benign, though admittedly
annoying) is expected in your version.

What I'm wondering is merely whether the -Q flag is still correct.

Cheers,
Florian

Fair enough. I was only concerned because of that --reboot switch in
there.

No, that only means that the node attribute being set has a lifetime of
"until the next cluster reboot", meaning it's only stored in the
volatile "status" section of the CIB.

Correct.  Sorry about that.

-Q is still accepted, though.
As it is accepted for a larger range of crm_attribute versions,
I'll keep it for now.
