Hi, I do not yet have HP-UX 8.0, and was wondering if HP-UX 8.0 includes an NFS automounter (i.e. dynamic NFS mounting on demand). The only NFS automounter for HP-UX that I am currently aware of is a public domain (i think) program called AMD, and I have heard that AMD has lots of bugs and other assorted strangeness. Thus, I am hoping HP includes an automounter in 8.0..... Does anyone who already has 8.0 know one way or another? Thanks much. --Todd Tannenbaum -- -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Todd Tannenbaum | e-mail: tannenba@engr.wisc.edu Computer Aided Engineering Center | Voice Ph: (608) 262-3118 University of Wisconsin-Madison | Fax Ph: (608) 262-6707

We use AMD in our multi-vendor (Sun, HP, Ultrix, SGI, AIX) environment and it works great - I don't know how we would get by without it. It even seems to handle system crashes on both the client and server side fairly well. There is one (minor(?)) problem with the current release when an NFS server is exporting multiple file systems. AMD will mount all of the exported file systems, and then after a timeout period, will attempt to clean up and umount un-used file systems (leaving, of course, the one that you are using). However, when you go to reference one of the file systems that has been umounted, AMD doesn't remount it and you're left with empty space (well, actually you have an empty directory that's the mount point on the server). However, the author has informed me that this is fixed in the next release - I believe he has a Beta release available on ucb.edu. I should say that we don't use the more "exotic" features of the automounter, but it works fine for our simple needs: /nfs/hostname/... By the way, one fix (spell that k-l-u-d-g-e) to the above problem is to add a few lines to one of the RC files on the client side that "busies up" the filesystems from servers that export more than one. alek, Dumb MBA Student, University of Colorado P.S. I'd also like to know if HP plans on including this in 8.x ?!?

I have been told that HPUX 8.0 does NOT have automounter. I have customers in town who MUST have it, but In general, is it required or not? I am trying to get some concensus. Respond by posting or email. I will summarize. a3197se.hp.com

It can use yellow pages for getting automount maps, in fact, the manpage says it was "designed as a value-added replacement for the SunOS 4 automount program". We still run automount on the suns. The amd YP maps are maintained by an awk script which builds them from the automount YP maps. The amd maps get regenerated whenever the automount maps change. A nice solution to the problem, and you don't have to wait for HP/UX to come up with something similar in 8.0. -bruce. -- Bruce Walton systems administrator bruce@ai.mit.edu MIT artificial intelligence lab 617-253-9667 cambridge, MA

Has anyone here tried running it on HP? We use amd in our multi-vendor network (DEC, HP, IBM, SGI, Sun) and it works like a champ (we use the Sun Automounter on those machines). There is a bug that causes it to "lose" filesystems if more than one is exported, but one can fix (spell that k-l-u-d-g-e) that, and the author has assured me that the next release will provide a real fix for this (but hey, who needs to worry about multiple file systems/partitions from HP systems :-) FYI: We do not use the more advanced features of amd, but it sound like both Bruce Walton at MIT and myself are happy users of it.
