Cheers -------- Original Message -------- Subject: [xfs-masters] [Bug 11813] New: xfs filesystem exported via nfs don't work in 2.6.27.3 Date: Thu, 23 Oct 2008 12:32:51 -0700 (PDT) From: bugme-daemon@bugzilla.kernel.org Reply-To: xfs-masters@oss.sgi.com To: xfs-masters@oss.sgi.com http://bugzilla.kernel.org/show_bug.cgi?id=11813 Summary: xfs filesystem exported via nfs don't work in 2.6.27.3 Product: File System Version: 2.5 KernelVersion: 2.6.27.3 Platform: All OS/Version: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: XFS AssignedTo: xfs-masters@oss.sgi.com ReportedBy: francois.valenduc@tvcablenet.be Latest working kernel version: 2.6.27.2 Earliest failing kernel version: 2.6.27.3 Distribution: Gentoo Hardware Environment: Software Environment: Problem Description: With kernel 2.6.27.3, it's impossible to use a xfs filesystem exported via NFS. I am using gentoo and I share a portage tree mounted on an xfs filesystem via NFS. Each time packages are fetched, the emerge process is blocked. It seems the problematic commit is the following: commit c068663ae65e507814545b59a8e2090f48a85613 Author: Christoph Hellwig Date: Sun Oct 12 14:30:44 2008 +0200 xfs: fix remount rw with unrecognized options commit 6c5e51dae2c37127e00be392f40842e08077e96a upstream When we skip unrecognized options in xfs_fs_remount we should just break out of the switch and not return because otherwise we may skip clearing the xfs-internal read-only flag. This will only show up on some operations like touch because most read-only checks are done by the VFS which thinks this filesystem is r/w. Eventually we should replace the XFS read-only flag with a helper that always checks the VFS flag to make sure they can never get out of sync. Bug reported and fix verified by Marcel Beister on #xfs. Bug fix verified by updated xfstests/189. If I revert it, the problem doesn't occur.
