Backup solution.
by foo 16 Oct '00

16 Oct '00

Ok, so I've been trying to figure out the "optimal" backup solution for my environment for awhile and haven't had much luck. I know this topic gets beaten to death, but if you can indulge me for a moment that'd be great. I have 2 760's with a 1/2 TB each (in a cluster). We'll be adding a 720 with ~1/2 TB very soon, and expect our overall storage to at least double in the next 6-12 months. We have approximately 25 servers (sparcs of various flavors) using the storage. We'd like to have a unified solution for backing up the netapp's as well as all of the servers. The questions are: 1.) Which tape library to buy (leaning towards SpectraLogic Bullfrog with 4 drives/40 tapes). 2.) To connect the library to the network via gig-e or to the netapp's via FCAL. 3.) Which software to buy and what to make it do (eh NDMP blah). Did I miss anything? So if you had this environment today what kind of solution would your propose? -Brian

RE: cifs.home_dir values

If I may submit a summary: From paul.benn(a)netapp.com: options cifs.home_dir vol\vol0\homes,vol\vol1\more_homes Data ONTAP 6.0 has another new option as well called "cifs.home_dir_namestyle." This option allows you to change how a username is used for mapping the home directory. Here are the three options with descriptions: ntname (or nothing): This is the same as with ONTAP 5.x. The user's home directory name must match the user's NT domain account name. mapped: The user's home directory name must match the user's mapped UNIX user name. domain: Under the root home directory (set with the cifs.home_dir option), you need to create one subdirectory for each domain that the filer trusts. Each user's directory is then created under their respective domain directory. The user's home directory name must match the user's NT domain account name and the domain directory must match the user's domain. and from Anissa.Mohler(a)netapp.com: Actually the syntax will be: options cifs.home_dir /vol/vol0/homes,/vol/vol1/more_homes If you type it wrong you will get a friendly error message :) There are many different ways of using home directories in ONTAP 6.x like Paul mentioned. It is one of the cooler new features from a CIFS point of view. Meanwhile, back in 5.3.x-land, there was from Eli.Lopez(a)netapp.com, jkrueger(a)qualcomm.com, and Moshel.Linzer(a)nsc.com: > > > On Wed, Sep 20, 2000 at 09:23:04AM +0200, Eli Lopez wrote: > > > > BTW, you can create a soft link on the filer called QTREE1 pointing to > > > > /vol/vol1/QTREE1 and mount using the link name. > > > > > > Cool!

So without quoting all of Chris' email, you can set your cifs homedir to a directory full of symlinks (userid -> /path/to/homedir), and each user will get a share to his own homedir upon login! Cool undocumented feature. And it appears to be true that some 6.X release will have multiple homedir paths, but this is still more versatile! So we ask: Will support for that most excellent symlink trick persist into ONTAP >=6? -- Moderation in all things, except love. Louis

Re: FILERS IN A HIGH-TRANSACTION SYBASE APP ENVIRONMENT
by Rick Hulsey 16 Oct '00

16 Oct '00

We did some performance testing on HP K class boxes running HP-UX 10.20 and 11.0. We found that the Netapp over Gig-E was on average about 30% faster than the HP Mod-20 disk arrays (AKA CLARiiON 20 slot) configured in RAID 5 for our application queries. We are planning to wait for more testing on Sybase 12.5 to make the move to the filer because the move to 12.5 will be a dump and load of our existing databases anyway.

NIS groups not showing up
by Lance R. Mehle 14 Oct '00

14 Oct '00

Hi all, I have a problem that I was wondering if any of you have seen. We have a little over 2000 groups in our NIS+ environment. When I check the nis_cache file on the filer about 399 are missing. A ypgroup also shows the group(s) missing from the filer although a ypmatch can find the group(s). It also appears that the same groups are effected all the time. The groups are fine on the UNIX side. Help! Lance

Hello James, If you're using Data ONTAP 6.0 or later you can specify multiple directories on one filer. The option you need to set is called "cifs.home_dir" and you can use a comma separated list with a maximum of 255 characters. Here's a sample command: options cifs.home_dir vol\vol0\homes,vol\vol1\more_homes Data ONTAP 6.0 has another new option as well called "cifs.home_dir_namestyle." This option allows you to change how a username is used for mapping the home directory. Here are the three options with descriptions: ntname (or nothing): This is the same as with ONTAP 5.x. The user's home directory name must match the user's NT domain account name. mapped: The user's home directory name must match the user's mapped UNIX user name. domain: Under the root home directory (set with the cifs.home_dir option), you need to create one subdirectory for each domain that the filer trusts. Each user's directory is then created under their respective domain directory. The user's home directory name must match the user's NT domain account name and the domain directory must match the user's domain.

RE: Trivia: what do the splodges on the LCD represent?

The scale is "realative" to recent readings. If the last reading or so was 12, and the current one is 3000, it'll peg. If the last reading or so was 3000, and the current one is 12, it'll sag.

Ten splodges equals how many ops? It looks to me more like some sort of autoscaling based on a rolling average, as I have seen the bar graph shoot off to the right during slack times when the number is relatively low compared to its rated max ops/sec.

After staring at that thing and wondering myself, it looks to me as if it is sort of a sliding rate-of-change meter. When there is a big surge in #/Ops over a short period of time, bar jumps up a lot. Ditto for a big decrease in ops, shaving the bar. However, I've seen the bar nearly pegged with a relatively small number of ops (say, 400 or so) and hanging around 50% when the machine in question was pushing as many as I ever have seen it push. In general, I think the main purpose is to have Cool Blinky Lights. -j
