opensm logs can go anywhere in size?

opensm logs can go anywhere in size?

[Or Gerlitz]

Hi Alex,

I just noted that opensm logs can go anywhere in size when one of my
nodes had no space left on device after the opensm log level was raised...

I see that the rpm provided with RHEL6 is setting an  
/etc/logrotate.d/opensm
entry which is a copy of ./scripts/opensm.logrotate from the opensm git 
saying

/var/log/opensm.log {
     missingok
     notifempty
     copytruncate
     weekly
     compress
}

this lacks size limitation, isn't that?

I opened ofa bz ticket #2280 to track that,

Or.

It's a good point. What should be the limit? 1MB, 10MB, 100MB? How many
history files (rotate) should be kept?
Moreover, this flooding would also happen if you don't enable logroatate, so
should we enable some default limit to opensm log (--log_limit)?
