RE: EMC IP4700 vs NetApp F740 (philosophical/OT)

That doesn't make it true and doesn't make me >credible just because I claimed it and refute when someone else says that it >doesn't. This mindset is beginning to worry me a little. I expect a certain amount of sales banter and exaggeration. I can live with some promotion of one companies product and trashing of another by a company sales rep (although the degree to which direct comparisons are made through advertising surprises me - e.g. this liquid plumber is better than that one because we've done tests so don't buy that product as it's crap). But to sit down with a technical person from one organisation and ask specific technical questions on their company's product and apparently get lied to from not asking the exact specific question/misinformed is going a little beyond the pale. Are we heading towards the situation where a buyer needs to get products in on eval from rival companies each time because they cannot trust the technical claims of the vendors? Couldn't our time be better used rather than each company going over the same ground at every technology jump or new product? To take the example above, if someone claimed that their car did 150mph and 60mpg, but then told me when I asked them directly that was only on a downhill slope of 45 degrees on a specific road in the middle of Germany and they actually get about 110mph on a flat road and 25-30 mpg during Interstate driving, I can deal with that. From what I've experienced, it seems to be akin to asking if a car is petrol, being told it is and then finding out I have to fill it with diesel to get it to work. This may well be because I'm a stranger in a strange land (an Irishman in Houston) but is this normal business practise here? I'd be interested in how everyone else sees this.

Re: more fun with quotas
by Tom Reingold 11 May '01

11 May '01

I believe it is not necessary to have quota trees in order to have quotas. But it is highly advisable. I highly recommend putting all user home directories in quota trees. If you don't want to make false barriers, put all the users in a single quota tree. This will prevent a disaster. It's possible to have a disaster (well maybe the word is too strong) if your filer fills up. If it fills up, you could truncate an essential file such as /etc/passwd. If the quota tree(s) add up to slightly less than the entire volume, then users will never fill up the filer. Unfortunately, if existing directories are NOT in a quota tree, you have to move them into one. This can be extremely time consuming. I don't know a way around this. You may have to have a night where the filer is unavailable to users while you make the move(s).

RE: NetAppCertTest
by Fairchild, Peter 11 May '01

There are three 1 hour tests **The Hardware Test covers the 700 and 800 series filers, FC7-9 and DS14 storage shelves, the basics of racking and connecting them, and a bit on back up technology. **The General Knowledge Test looks at elements of Unix and NT, networking, DOT 5.x & 6.x (Normal Commands only), and some break/fix scenarios. **The Configuration Test examines just that: Can you configure a filer, storage shelf, and basic back up system? Volumes, qtrees, quotas, security styles, VIFs, snapshots, autosupport, OS upgrade, dump/restore, etc. Nothing tricky in these tests. Just the fundamentals. Tricky comes at the Professional level where troubleshooting and performance tuning come into play. How to prepare? Take the Hardware and ONTAP System Administration classes and DO THE LABS. Keep up with the NOW site and toasters (you guys are a great source of material ;->) and you should have no problem. Oh, and there is a grid covering all of the above in greater detail on the NOW site. Peter W. Fairchild Technical Certification Program Manager Educational Services NetworkAppliance, Inc.

Question on quotas...
by Allen, Pat 11 May '01

11 May '01

Hi all, I'm in the process of migrating our user accounts from one F740 to another; both are running 6.0.1R3. On the existing F740, I had a separate volume for the user home directories but I want to keep these in the root volume on my new filer. So I created a qtree (with Unix security style) in my /vol/vol0 volume named users. My quotas file looks like: * user@/vol/vol0 - - * user@/vol/vol0/users 500M - # User Quota My understanding from the documentation indicates that you can put a quota on a qtree - the man pages for the quotas file even shows an example. What I'm finding is that the 500M quota is being applied to the entire /vol/vol0 volume rather than just the users qtree. This is not what I want since I'll have other qtrees there as well and I don't want files in the other qtrees to impact the home directory limit. Does anybody have any suggestions??? On a similar subject, I'm finding that my user mapping isn't working as I would expect. When I copy files from a Windows client to my home directory, all the files end up being owned by root. Obviously, this screws up my quotas. The user name in the NT domain always matches the user name in the NIS domain. This occurs on both the old and the new filer; I even have an explicit mapping configured in usermap.cfg on the old filer. Any suggestions on what is going on? --- Pat Allen (pat(a)mbari.org) Monterey Bay Aquarium Research Institute (MBARI) 7700 Sandholdt Rd, Moss Landing, CA 95039 (voice) 831-775-1724; (fax) 831-775-1620
