Bruce Fields" To: Christoph Hellwig Cc: Dave Chinner , linux-nfs@vger.kernel.org, xfs@oss.sgi.com Subject: panic on 4.20 server exporting xfs filesystem Message-ID: <20150303221033.GB19439@fieldses.org> MIME-Version: 1.0 Content-Type: text/plain; charset=us-ascii Sender: linux-nfs-owner@vger.kernel.org List-ID: I'm getting mysterious crashes on a server exporting an xfs filesystem. Strangely, I've reproduced this on 93aaa830fc17 "Merge tag 'xfs-pnfs-for-linus-3.20-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/dgc/linux-xfs but haven't yet managed to reproduce on either of its parents (24a52e412ef2 or 781355c6e5ae). That might just be chance, I'll try again. I can also try a serial console or something, but for now I'm not getting a lot of information about the crashes. The filesystem in question isn't on a block device available to the client, but I'm still seeing occasional GETLAYOUT and GETDEVICEINFO calls; I suppose the client's getting that far, finding no devices it can use, and giving up? Sorry for the incomplete report, I'll pass along more when I have it. --b.
