Do you know an easy way to unset floppy-boot? on a running machine, without halting back to `ok '? If there isn't a way at the moment, I recommend that NetApp implement something a la Solaris' ``eeprom'' command, which allows modifying OpenBoot environment variables, and is really handy when you don't want to take a machine down to change stuff, or you can't get to the console due to unforseen problems (such as when you terminal concentrator locks up that port :( ).

Y2K: Any one rolled a filer forward & backwards?
by Garrett Burke 23 Apr '99

23 Apr '99

Hi All, As part of my Y2K testing I intend rolling the date forward on my filer (F230, currently 5.2.1, NFS & CIFS) to just before midnight on the 31st and then watch it as it ticks over midnight. So far, so good. The issue I have (assuming the filer is Y2K compliant!) is rolling it back again. Has anyone rolled their filer forward and then back again to put it back into production? Were there any glitches? There will be files that will have modified dates in the future, but these can be a copy of some production data which can be deleted after the test. GB

Another item that comes to mind is your /etc/syslog.conf (assuming that you have one) and other dynamicly read files. One would hope that the timers used to check this stuff actually use incrementals , not absolute time values - that is set a timer , count down to 0 when you reach 0 check file x and not check the clock every second and at 01:45:30Z01Jan2000 check the status of x. Otherwise when you set your time back, these dynamic files might not be read for some time B-}( ----- Stephen C.

Hi Ozzie, If there was a problem with going back then I'd end up restoring from tape which would probably result in downtime during business hours. Checking with others at least gives me some confidence that I wouldn't end up having a conversation with management if I hadn't checked which would go something like: Mgt: Why did you do it? Me: Y2K test Mgt: Has anyone else done it? Me: Don't know, didn't check Mgt: What do you mean you didn't check? Me: (gulp) Mgt: Better start printing your CV out! Me: can't, it's on the filer which has crapped itself! 8-) You get the picture. Many people didn't expect the Y2K problem either. 8-) GB > ---------- > From: Ozzie Sabina[SMTP:ors@cimedia.com] > Sent: 21 April 1999 17:56 > To: Garrett Burke > Cc: 'toasters(a)mathworks.com' > Subject: Re: Y2K: Any one rolled a filer forward & backwards? > > > I have done this and then reset it with no problems (I'm not sure why > you'd expect any). > > (This was with the 5.3 release) > > Oz >

Yes, Dave, but not to put too fine a point on it, this is the same thing that has been said by some employees and customers for years. I'm sure you're sincere, but I think people so far have found Netapp's progress in this area less than satisfying. There has been some, and the classes are a good step, but a lot more should be done. Saying "we're trying to get our arms around this problem in engineering" lacks a little credibility when you realize that you've been saying the same thing for 3-4 years. It might be more honest to say that "we decided to spend that time and money on more revenue-enhancing engineering projects" and that's a sound business strategy, but let's not pretend that Netapp has only now suddenly discovered this issue and is trying to come up with the best solution. Sorry for being a little critical; I rarely am on this list, but you hit one of my hot buttons. :) Bruce

There is no way to do this, and I agree with you that this is an unpleasant situation. On several occasions I have had to set a box to floppy boot (usually when an emergency forces me to run a 25/7 or prev_cp and I am somewhat distant from physical console access but can get to a console server over the net) and if I am using this hack to get the box running in the first place I am in no hurry to run it through another reboot just to turn off the floppy boot option, particularly if I am not sure the system will come up again if I do happen to reboot it... jim

>> they should've spent more money on books and >>less on leather jackets..... Seems like a good opportunity to introduce myself...NetApp has recently made a substantial investment in the Educational Services organization, allowing us to improve/expand our base courses (and materials), as well as develop new courses. The NTAP 101 student manual has been completely rewritten (with a tab based TOC) and the NTAP 202 new manual is in the works. The new manuals are a different format and have more of the 'lecture' included, requiring less 'note taking' by the students (although more vs. less note taking is a highly debated subject in the training world). Classes, overall, have more lab time (input from our class evals). We are also creating WBT (web based training). Our first WB course is currently in beta. We have scaled down the 'giveaways' in class (they were pretty substantial) but have improved the multiple student/multiple class discounts. A point I'd like to make specifically on Jason's comment: >Even after taking the class I doubt I'd play with the special commands without tech support on the phone... at least not on a production filer. This is an important point which we stress in the 202 class. For reference, here's the URL to our web page: http://www.netapp.com/support/training.html Another URL for additional feedback and/or input on new/extended courses is: http://support.netapp.com/now/survey.html If you'd like to be on our mailing list, you can fill out a form on the web or send e-mail to registrar(a)netapp.com.

But that wasn't really the goal of the floppy boot; it was for things like installs and boting up a previous OS when the current one is crashing your filer and so on. Bruce

Have you seen the nice black polo shirts? My sales rep still owes me a couple, but I'm pretty sure he's avoiding me.

I'd have settled for a Table of Contents -- an Index would've been great. The instructors were good. Too bad I don't have a phonographic memory. They did do a good job of answering any odd questions I could come up with. >there are times when the docs aren't handy and I need to remember if it is >26/7 or 28/7 that fries my disks... Not sure about putting the docs on the web. I think that's asking for somebody to trash their filer and blame NetApp for showing them how. Even after taking the class I doubt I'd play with the special commands without tech support on the phone... at least not on a production filer. jason

It used to be covered in the NTAP 202 class (if you took the class hunt around in the binder full of PowerPoint slides they called a book for "prev_cp - boot from prior consistency point" -- they should've spent more money on books and less on leather jackets) in the Special Commands Section. This worked with a 4.1.x boot floppy in class, not sure about the 5.x boot floppies. As I recall it was for recovering from a severely fubar'd filesystem. As for the date flipping, I have two F740s which aren't doing anything until I get patches to 5.3D2 (maybe Friday last I heard) to make cluster failover stable, so I'll mess around with it and get back to the list.

ramping performance
by Graham Knight 21 Apr '99

21 Apr '99

While doing some transfers to an F760 (5.1.2P2) the perfomance seems to ramp from good to lousy. I can find nothing wrong with the network - this is data coming from a system on the same subnet (100tx-fd). Data transfers between other systems on the same segment do not show these types of performance problems - here's a typical output from a sysstat 1: ( i am reading from one place on the filer and writing to another) CPU NFS CIFS HTTP Net kB/s Disk kB/s Tape kB/s Cache in out read write read write age 12% 232 1 0 949 947 640 0 0 0 12 34% 644 0 0 2425 2445 2336 0 0 0 12 12% 233 2 0 1020 1015 1049 0 0 0 12 4% 0 1 0 1 0 0 0 0 0 12 4% 2 0 0 0 0 0 0 0 0 12 19% 488 4 0 1970 1984 1724 0 0 0 12 49% 448 0 0 1700 1656 2226 7075 0 0 12 15% 139 0 0 128 158 148 3976 0 0 12 4% 0 1 0 0 0 0 0 0 0 12 19% 139 8 0 601 613 708 0 0 0 12 25% 621 0 0 2702 2719 2342 0 0 0 12 19% 467 0 0 2049 2027 1888 0 0 0 12 4% 16 1 0 20 3 0 0 0 0 12 4% 91 1 0 15 16 0 0 0 0 12 Anybody have any insights into what might be causing this?

Just FYI (nothing official), but I can say that in the limited testing I did with Legato over CIFS to the filer everything seemed to work just fine. I was able to back up and restore both UNIX- and NTFS-style files with no problems. The security and other metadata were fully preserved. Make sure you are doing the backups and restores from an NT admin account that maps to 'root' if you are working with files that have UNIX-style security. The one problem I remember is the same one Michael Salmon mentioned: make sure you are accessing the filer as a domain administrator, not the local administrator (which is the default unless you specify "domain-name\administrator").

Anybody using 3com switches with NetAPP?
by Jaye Mathisen 16 Apr '99

16 Apr '99

I have both my ports on a linkswitch 3000, at 100mb, full-duplex. Both ends are configured manually for 100mit, full duplex. I do not believe when i was running 4.3.4, that I got any errors. But now, with 5.3, I'm seeing occasional errors. (a few every 10-15 seconds). In this VLAN, there's only 1 other device talking to the netapp, and it's configure for 100mb, full-duplex as well, and it sees no errors either coming or going. As I said, I believe this is new behaviour. I have rebooted everything just to make sure, and double checked it all, and it's all full duplex 100mbit. Cabling is short, and tests fine on a Fluke 682 lan meter... Anybody else seeing something similar before I go knocking on Netapps door?

Yeah, this has been a well known problem for years, but I had trouble getting action on it until engineers actually had to deal with the problem first hand and realized just how bad it was. As to the fix, I don't recall what it was, but I recall a proposal similar to the one you listed being considered and rejected (for example, your suggestion wouldn't work, since when the user fails to go over quota they'll generally fall right back under it, thus resetting the flag). >[Hmm; I should put support(a)netapp.com (or whatever) on autosupport; >maybe then they'll listen after getting a 30MB email message every >week ;-] I think they already filter such things.

Samba client and filers
by Garrett Burke 16 Apr '99

16 Apr '99

Hi, Anyone know of any issues with smbclient (version 1.9.18p8) and filers running CIFS (OnTap 5.2.1)? Session setup is failing. I can use smbclient to connect to my NT servers but not the filer. I notice from the debug output of smbclient that it says "Using encrypted passwords" Could this be the problem? Can't see anything on the smbclient man page to force it to use unencrypted passwords. Here's some "-d 3" output from smbclient: Connected max mux 32 max vcs 1 max raw 65536 capabilities 0x42dd Sec mode 8195 max xmt 8192 Got 8 byte crypt key Chose protocol [NT LM 0.12] Server time is Thu Apr 15 14:16:23 1999 Timezone is UTC+1.0 Password: Using encrypted passwords Session setup failed for username=<username> myname=<FreeBSD hostname> destname=TOASTER ERRSRV - ERRerror (Non-specific error code.) (Before you all say "use NFS", I'm writing some monitoring tools that will run on a FreeBSD box and will actually fetch a file from the filer and calc a CRC to ensure it's ok. This way I know the file service is available) Thanks, GB

Daniel Quinlan writes: > > Exceeded quotas are also logged to /etc/messages. > This is *damned* annoying. With 2500 students all hammering one of my filers (a F330 in this case), we generally get /etc/messages.? ranging in size from 10 MB to 150 MB (yes, 150 *megabytes* in a week!) (My local NetApp tech asked to get off my autosupport because the mail was too large ;-) This causes the filer to choke (i.e, 100% load) whilst sending the `autosupport' email, and my mail program gets a bit unhappy with it. I wrote a procmail rule to trim the mail down to a more manageble 30KB: something like: :0 w: root/netapp/$LOCK * ^TOnetapp-admin(a)cs.rmit.edu.au | egrep -v '(last message repeated [0-9]+ times$|(disk|tree) quota exceeded)' | $RCVSTORE +root/netapp I submitted a Request for Enhancment on how to solve this. Basically, I asked for something along the lines of: * Add a flag to the per-quota-entry data structure which the filer uses to maintain current state. If this flag is set, it indicates if a message has already been logged about that quota being exceeded. * Every time the quota entry is checked (during a disk write, or whatever), do the following: if (quota not exceeded) { flag = 0 } else { /* quota exceeded */ if (flag == 0) { syslog("quota exceeded ...") flag = 1 } } I.e, don't bother logging a message if that user has already had a message logged about them. However, if they go under quota, clear the flag, so we get a message when they exceed it again. The only response I've received (second hand) is along the lines of ``we've fixed it, but a different way''. [Hmm; I should put support(a)netapp.com (or whatever) on autosupport; maybe then they'll listen after getting a 30MB email message every week ;-] > > I'd recommend using a userland program (on login) to regularly tell > users how close they are to exceeding their quota, in addition to > monitoring quotas for your own information. > I wrote a perl script which can do all sorts of funky reporting based on the output of `quota report', including playing ``what if'' games based on the quota report and the `/etc/quotas' file you're about to apply. It currently works for OnTAP 5.2.1, although I could probably hack support back in for 4.x if people wanted it. Checkout: http://www.cs.rmit.edu.au/~lukem/src/quotarep An aside; on our main student filer (an F330), we have nearly 6000 users, and 2500 separate quota entries; we generate an individual quota entry per student based on subject enrolment. Works quite well, although the `quota resize' takes over two minutes to complete, and I'm a bit sick of the huge messages file :/ We've had our share of quota bugs (especially the ``quota -v doesn't display anything'' problem), but in general, the NetApp quota system works well. It's definately easier to manage than standard UFS quotas (as well as the ability to recalculate on the fly; UFS quotacheck requires a quiscient filesystem to work).
