We have a FreeBSD host (FreeBSD 9.1-PRERELEASE #0 r244125) configured = with a few ZFS storage volumes. Recently we attached an external volume = to the host, created a GELI-encrypted ZFS volume, and copied some data = to it. When completed, the device was not disconnected properly. Now, = any ZFS/zpool commands that attempt to touch that missing device are = left hanging in perpetuity on the host because it seems to think it can = still access the volume when in fact it cannot. This is not affecting = any other functions of the host besides a few scripts that are intended = to check the health of the attached volumes. Is there any way to clear the apparent presence of this missing device? = We tried to re-attach the volume and perform the necessary ZFS = export/import, but these commands now hang as well (the -f option has no = effect). No doubt a reboot would take care of it, but there are some = functions running on this host that we do not wish to interrupt, if at = all possible. Can anybody make a recommendation? Thanks Joe
