Andersen" To: freebsd-hackers@FreeBSD.ORG CC: sclawson@cs.utah.edu, mike@fast.cs.utah.edu, danderse@cs.utah.edu Subject: nfs intr hang and mount options X-Mailer: VM 6.43 under 20.4 "Emerald" XEmacs Lucid Message-ID: <13900.47610.325085.20936@torrey.cs.utah.edu> Sender: owner-freebsd-hackers@FreeBSD.ORG Precedence: bulk X-Loop: FreeBSD.ORG It seems possible that the problem is related to the handling of the 'intr' flag on NFS mounted filesystems; the filesystem where we replicate the crash is mounted with: rw, overlay, intr, bg, quotas, grpid, vers=2 (overlay is a solaris thing). If we mount the filesystem with a diffent set of options: rw, grpid, resvport, nfsv2, nosuid, nodev then we can't replicate the problem. Not too surprising, since the problem is triggered by a SIGINTR, but probably a reasonable datapoint to watch. -dave To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
