(After all, even hitting the reset button is not supposed to get an NFS server into an inconsistent state.) Is it possible that your Slowaris NFS server sometimes trashes your device nodes? Note that FreeBSD uses 32-bit major/minor numbers, this is not a problem for the NFS protocol (not even for NFSv2 -- it did infact reserve one 32-bit integer field for these numbers), but might be a problem for some server. The upper bits are only rarely used, so you might not immediately notice the problem. Watch out for things like /dev/rsd0.ctl which have the 0x20000000 bit set in the minor number. -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ -- NIC: JW11-RIPE Never trust an operating system you don't have sources for. ;-)
