Interesting, apparently the number one provides in the 'ceph log last
<num>' command is not the number of lines to display but the number of
lines to search for a match.
So in your case you should still see your osd log output about the
large omap if you pick a large enough number. My interpretation was
that the number of lines you provide is the number of lines to be
displayed in the selected log level. This needs to be documented.
Zitat von Eugen Block <eblock@xxxxxx>:
I just played a bit more with the 'ceph log last' command, it
doesn't have a large retention time, the messages get cleared out
quickly, I suppose because they haven't changed. I'll take a closer
look if and how that can be handled properly.
Zitat von Janek Bevendorff <janek.bevendorff@xxxxxxxxxxxxx>:
That's where the 'ceph log last' commands should help you out, but
I don't know why you don't see it, maybe increase the number of
lines to display or something?
BTW, which ceph version are we talking about here?
reef.
I tried ceph log last 100 debug cluster and that gives me the usual
DBG spam that I otherwise see in the MON logs. But there are no
messages above that level.
