Subject: df strangeness on solaris 9/sparc with nfs
Date: Mon, 07 Mar 2011 22:18:09 -0500

Hi All,

I'm building an 8.10 update package for OpenCSW and found what I
believe to be a bug in df (8.8 is the current version).  This is
uncovered by the fiemap_capable_ function in the test suite and causes
the cp/fiemap-perf and cp/fiemap-2 tests to fail on sparc only.

The filesystem is NFS in both cases (from the same source).  I don't
presently have time to dig into the cause (and it may be fixed in
newer 8.9 or 8.10 anyway) but will try to do so in the next few
days...Please let me know if there is something specific you'd find
useful in the meantime.

On i386, I get:

$ gdf --version

Hi,

That specific 8.10 test failure is addressed separately upstream.
I'm leaving this bug open to record the df behavior you detail above.
It triggers when df can't read the list of mounted file systems
(why can it not on your sparc system?)

We may try to match the output of statfs() in this case,
and if no direct match, then fail?  I'm not sure.

cheers,
Pádraig.

Hi Pádraig,

Thanks for the quick reply and apologies for my slow response.

Ok, that's good to know.

It is able to read the list, but it then proceeds to behave very
differently compared to the i386 version.  I've attached truss output
from the two boxes.  Hopefully it's of use.

Thanks

Can you send the contents of the two /etc/mtab files.
Perhaps there isn't a type field in the sparc one,
or perhaps your libc is behaving differently on sparc.

thanks,
Pádraig.

Certainly.  See attached.

Also, the sparc host is a solaris 9 branded zone inside a solaris 10
update 9 box, while the i386 box is native.
