Re: rw? no, ro.

Jim, >Any ideas? This is a busy system so rebooting from floppy to bypass the >rc file and then trying another admin host is something I'd like to avoid, >though at this stage I don't see an alternative. You can unexport root using "exportfs -u /" (note that the root may alternatively be exported as /vol/vol0/ at release 5.x) You can use "exportfs -i -o access=new.admin.host,root=new.admin.host /" to re-export the root directory to a different host or list of hosts. Have you opened a call with our support on this? Andrew Bond System Engineer, NetApp UK

exports syntax
by just me. 22 Aug '98

22 Aug '98

Has anyone found better documentation on 'exports' syntax than the crappy 'administrators' guide once-over? I am specifically interested in using a 'files' based netgroups map to clean up permissions, however the administrators guide suggests that usage is somewhat non-intuitave (as does my experimental results) yet stops short of providing useful information. It does however reference one of the mysterious man pages, which I have never been able to get Netapp to give me. In fact they deny their existance. Anyone got the skinny? thanks. --matt(a)bikkle.interq.or.jp------------------------------------------- Matt Ghali MG406/GM023JP - System Administrator, interQ, Inc AS7506 "Sub-optimal is a state of mind." -Dave Rand, <dlr(a)bungi.com>

Snapshot Bug
by Raymond Brennan 21 Aug '98

21 Aug '98

Hello, I've run into a snapshot bug and was wondering if anyone else had. The details are basically that the filer ( an F520 with 128 Gb of disk, 128 Mb RAM, a Dec ALPHA CPU and running ONTAP 5.1D3) hangs when creating snapshots as instructed by BudTool. It is an ONTAP problem and is stopping me from doing backups. Has anyone else been hit with this ? :)

Bug with ACL's & MS based "Save As"
by Weeks, Thomas 20 Aug '98

20 Aug '98

Hi all.. Have a NetApp F230 running OnTap 4.3.4. I am usnig the CIFS based "cifs.home_dir" option (with a "catch all" UID in the passwd file) to allow NT Authenticated users in my domain to each map their own home drive. When one of our users (running Win98 & MS-Office 97/Outlook97) saves documents, or file attacments from any of his applications to his CIFS mapped NetApp Home drive, they have no problems. Saves fine every time. HOWEVER, if he clicks on <file> <Save As> and directs it to the NetApp CIFS drive mount, he gets the error: "[MS OUtlook] Cannot save the attachment. Access Denied." But (from Outlook) if he clicks AND DRAGS the file, or copies it to his desktop first & then to the drive mount, there's no problem. Similarly, if he just tries to do a SAVE (and not Save as) then it works fine. THE PROBLEM IS JUST WHEN HE TRIES TO "SAVE AS". I looked at the user's dir. His permissions are 777, and his dir's UID (and all file/dirs under it) match his UID in /etc/passwd on the filer. Has anyone seen this behavior before?

New F700 Series
by sirbruce＠ix.netcom.com 19 Aug '98

19 Aug '98

Okay, so the F700 series has been announced. I am, however, left with many questions: 1. Are these models Alpha based? Pentium? Other? What are the relative speeds, so I can compared to the previous models? The F760 appears to be about 50% faster than the F630, but I'm sure that's spread out over several components, not solely due to the CPU. 2. When can we expect even preliminary SPEC SFS numbers? 3. When can we expect Netbench numbers? One would guess they would be in the range of 30MB/second. 4. What is the maximum network connectivity? The spec sheet mentions 8 PCI slots, but I don't know if that includes those for tape and/or FC-AL. Bruce

The F760 actually has 9 pci slots, of which one is dedicated to the nvram card (just like in other filer models). Of the remaining 8 slots, 3 are 32-bit pci and 5 are 64-bit pci. And, yes, the power switch is in the back! Hope that helps! rgl

As I said, I *read* the spec sheets. They don't say whether all 8 slots are really "free" and it doesn't mention 64bit slots, either. Your answers were what I was looking for, but don't say that they're in the spec sheet, 'cause I looked there first and they weren't. Bruce

RE: /vol and client automounter paths.
by Kelly Wyatt 14 Aug '98

14 Aug '98

We seem to have no problem mounting stuff that is exported as /vol/volN. The automounter mounts it as /nfs/filer/vol/volN. That is OK. It works with /vol/vol0 anyway. And we have a few filers with /vol/<user defined name> that we know works. I realize this is probably not a filer problem and that this won't happen if you have a single volume filer. I just wanted to let people know what we have experienced using the "mixed style" exports. This might come in handy should they ever have a multi-volume filer. We have had no such problems with our single volume 5.01 machines. We are just fortunate (?) that this happened just before the regular monthly outage and we can change the filer exports and reboot all workstations this weekend.

RE: /vol and client automounter paths.
by Kelly Wyatt 14 Aug '98

14 Aug '98

I'm curious about this. We have had a situation where our automounter daemon (amd on hpux10.20) has been chewing up CPU trying to resolve a mount to a filer: Aug 13 21:30:00 build034 amd[4993]: No mount point for /remote/ronco/vol/vol1 - skipping Aug 13 21:30:00 build034 amd[552]: "/nfs/ronco.unx.sas.com" on /remote/ronco sti ll active Aug 13 21:34:27 build034 amd[5426]: No mount point for /remote/ronco/vol/vol1 - skipping Aug 13 21:34:27 build034 amd[552]: "/nfs/ronco.unx.sas.com" on /remote/ronco sti ll active This is showing up *hundreds of thousands of times* in the syslogs, and is causing out automounter daemon to take a 50-60% of the CPU across hundreds of workstations, if not thousands and filling disks with syslog entries. Our exports are: / -root=server2:server3 /home -root=server2:server3 /builddir -root=server2:server3 /vol/vol1 -root=server2:server3 Note that /vol/vol1 does exist. So, I read on the NOW site what I have pasted below. The second to the last paragraph is what seems to stand out to me - "If you use paths of the / form for export points in the root volume, the automounter might not be able to mount directories in other volumes, or it might create new directories in your root volume to serve as mount points." We are planning on changing the exports to: /vol/vol0 -root=server2:server3 /vol/vol1 -root=server2:server3 this weekend and rebooting all machines (and changing references from /nfs/filer/builddir to /nfs/filer/vol/vol0/builddir...). We are *really* hoping that this fixes the amd problem. Any thoughts about whether this is going to work or not... or if something else might be causing our automounter problem???? Note that we have this problem only with the filer ronco. The other filers at 5.01 do not have /vol/vol1 yet. Thanks, Kelly Data ONTAP 5.0R2 Export point notation Both / and /vol/vol0 identify the root volume. You can use either form to list exported directories in /etc/exports. For most purposes, the two forms are equivalent. However, when an NFS client requests a list of export points from the filer (for instance, as the result of a showmount -e command), the filer returns the paths exactly as they appear in /etc/exports. This affects the behavior of the automounter. For example, if toaster exports /, the automounter mounts the root volume for toaster on /net/toaster, but if it exports /vol/vol0, the root volume appears in /net/toaster/vol/vol0. If you have more than one volume, use paths of the /vol/vol0 form for all your export points in the root volume. If you use paths of the / form for export points in the root volume, the automounter might not be able to mount directories in other volumes, or it might create new directories in your root volume to serve as mount points. Note that /vol/ is not a valid syntax for filers

Re: /vol and client automounter paths.

Ummm, as far as the manual was concerned /vol/vol0/home should be accessible over the automounter as /home, likewise anything else on vol0. From what I read (which may be completely incorrect ;) only for volumes other than vol0 are you required to use the /vol/vol# syntax. I've set up a number of filer here and I'm referencing all homes and projects from /vol/vol0/dirname as filer:/dirname successfully. Soooo, looking at one of my filers... All directories in /vol/vol0 are "mirrored" in / under /net/filername, and also available over the automounter that way. --Steve > From jdavis(a)CS.Arizona.EDU Thu Aug 13 14:56:53 1998 > Date: Thu, 13 Aug 1998 14:19:13 -0700 (MST) > From: Jim Davis <jdavis(a)CS.Arizona.EDU> > To: toasters(a)mathworks.com > Subject: /vol and client automounter paths. > MIME-Version: 1.0 > > Due to some sloppy RTFMing, I apparently missed that as part of moving > from one F520 to another I need to change every fscking client's home > automounter map entries from > > user server:/home/user > > to > > user server:/vol/vol0/home/user > > (Or maybe try some symlink tricks but I'd really like to avoid that for > efficiency and general non-grossness.) > > <freak out>Aww, nutbunnies!<freak in> > > There appears to be some backward-compatibility mode iff (and the manual > isn't crystal-clear on this) you upgrade from 4.x to 5.x.
