The following reply was made to PR kern/122833; it has been noted by GNATS. From: =?iso-8859-1?q?Ga=EBl_Roualland?= <gael.roualland@dial.oleane.com> To: bug-followup@freebsd.org, leon.kos@lecad.fs.uni-lj.si Cc: Subject: Re: kern/122833: [snapshots] [patch] mountd fails on nmount() after UFS snapshot creation with mount Date: Sun, 11 May 2008 13:14:27 +0200 Same problem here. After looking a bit in mount and mksnap_ffs, this seems due to a difference in the way the snapshot is created : mount calls nmount(2), while mksnap_ffs only calls mount(2). There might also be differences in the options passed to the syscalls, that needs investigating. Note that mount sends a HUP signal to mountd after each successful mount (including snapshots), while mksnap_ffs does not, however manually restarting mountd after a mksnap_ffs does not exhibit the bug.
