It's about time the man pages for na_savecore and na_crash were updated, isn't it? They don't even admit the existence of core.*.nz files, which have certainly existed at least since 5.2.1.
I agree.
Incidentally, has anyone found a way of significantly compressing the .nz dumps before transfer to NetApp? When I tried gzip, I got only about a 2% reduction in size, which wasn't worth it.
Isn't that the point of .nz cores? They are pre-compressed.
<soapbox>
Incidentally, have you noticed that it now takes about five times longer to dump a core now that they are .nz compressed? This is a very frustrating "feature". The savecore process works while the filer is ON-LINE, whereas the dump process works while the filer is OFF-LINE.
If the goal is for the filer to be ON-LINE more than it is OFF-LINE, why delay the time it spends dumping with compressing a core when we could all gzip it when the filer is ON-LINE? Or why not put the compression code in the savecore process which can be executed after the filer is back ON-LINE?
I don't know about other SysAdmins, but I hate watching dots fly across the screen for 10 minutes while some Director of Engineering is screaming into the phone because their box isn't back ON-LINE. I'm especially frustrated when I know those dots could be doing their job after the Director has "enhanced their calm" when the box is back ON-LINE and making them money again.
</soapbox>

It would be nice if:
1) Compression was done during "savecore" rather than "dumping core" 2) Compression could be turned off via "options compress.cores.enable off"
Either would have the end result of allowing us to get boxes back on-line faster and compress the cores on our own time rather than on our customers' time.

Thanks!
