CIFS, ownership and chowning from nfs
by Rune Bakken 27 Jul '00

27 Jul '00

After on of the NT/Admins went bonkers last night moving a bunch of users to the NetApp (without consulting me first), I have found that appox 10% of the user catalogs is owned by root, with unix-style permissions are drwxrwxrwx, and I am unable to change owner or permissions from either nfs-side or using SecureShare tool on the NT. The users are unable to write to their nfs-mounted files At the time of migration, the usermap.cfg did not contain mapping of the Admin account/group to root, and wafl.nt_admin_priv_map_to_root on wafl.root_only_chown on Does anyone have a clue to what can remedy this? >>>>>>>>>>>>>>.rune -- Rune Bakken "I feel sorry for people who don't drink.

Hi! Are the qtree/volume security style "ntfs"? In that case right can only be changed by users with apropriate right in the NT domain/local groups. When you look at the acl's from the UNIX side they look like this sometimes. Ex in the case where the local Administrator group has FC on the files and the users ex has change. Does this make a sense ?

NDMP Questions
by jmiddlebrooks＠datalink.com 26 Jul '00

26 Jul '00

If anybody has dug deep into using Veritas Netbackup NDMP to backup the filer. 1) Since NDMP uses dump, if you loose tape 5 of 8 does that mean you loose the entire backup / restore? 2) Can you restore file X without spanning all tapes that are part of the dump? Any help would be greatly appreciated.

Hi All, We already updated Todd but I wanted to make sure to send this out to everyone: We've moved all the 'Tools & Utilities' over to the main download page based upon customer feedback that all downloads should be in one consolidated section on the NOW site. Go to the main download page (http://now.netapp.com/NOW/cgi-bin/software/) Towards the top of the page, in the 'Software Tools' section, you'll see the 'Tools & Utilities' link. We have also added in 'quick links' to RAWRITE, MRTG etc. so you can get to them directly from the software download page. (If you click on the 'Tools & Utilities' page, you'll find a consolidated list of all our scripts and tools. We also added columns which indicate if they are 'supported', 'recommended', etc.) Email me directly if you have any problems finding what you are looking for!

To preserve ACLs when copying you can just use scopy.exe. It comes with the NT resource kit. Alternatively you can use a backup/restore process. There are also some very nice third party migration tools, such as SecureCopy from smallwonders.com, which copy files+ACLs, shares, local groups, etc. between servers.

I believe every CIFS statistic that we keep is in MIB 1.2, even the propeller-head stuff IIRC, and most of them are in the MIB that ships with 5.3.x. Do an snmpwalk of .1.3.6.1.4.1.789.1.7 and you'll see everything that's there. There only seem to be two MIB entries for http running on a filer in MIB 1.2. They report the low and high 32 bits of a 64 bit quantity representing the total number of http operations. Please send mail to me directly regarding which other statistics would be desirable, and I'll file an RFE. Alan =============================================================== Alan G.

With WCCP 2 you will be able to in the (near?) future. And Foundry will hopefully add the support soon too...

So web servers can get access to it that way if they want to... ] Cheers, Niall

Yeah, I've also heard the case presented by the faction that proposes Mibibyte, Mibibit, Kibibyte, Kibibit, etc. (sp for all those) to denote the 2^10^3n quantities. Seems quite reasonable to me.. except in the face of enormous socio-linguistic inertia I'm not sure I'd fight that hard. It's very nearly always been denary powers in raw disk sizes. I still think the binary powers are firmly ensconced in RAM, file sizes and bandwidth (MHz -> Mb and MB seems to pose less problem for people headers and preambles notwithstanding) in the mind of both the novice and the old-hand. More same-old same-old I think. I'll continue using whatever units my listeners/readers will understand most readily - anything else is poor communication. The issue that causes _me_ the most irritation is when people insist on using lowercase 'b' in Kb, Mb, etc. when they really mean 'byte' which, for me, and I suspect for many of us, would suggest 'bit'. Or when they're inconsistent. Sometimes it's not always possible to deduce from the context what they really mean, and, worse yet, they often don't see the issue as a problem! > Camiel Vanderhoeven wrote: > > > > Yes, the Ki, Mi, Gi etc. prefixes are a nice initiative to avoid > confusion. > > However, I have never seen anyone who seriously uses it.

RE: Ndmp vs. Nfs backups.
by Kelly Wyatt 25 Jul '00

25 Jul '00

We use DLT7000, the compression devices on the netapp. Right now the master for these backups is a sun ultra 2. He really does not do much other than schedule jobs, perform database updates, etc. He has to create the list of files to backup and has to have a lot of temporary disk space and memory to handle this task. During the backups, most (all?) of the CPU cycles come from the filers -- all 760's. Here is some info on our sun: Sun Ultra 2 UPA/SBus (UltraSPARC-II 296MHz) with 384MB of memory. We have a 70GB raid array for /usr/openv to allow space for database growth. I thought he had more memory it may have been "borrowed" for an unexpected project. We do stagger our backups so that all backups jobs are not going for resources at one time. Each filer volume is a class for a lot of reasons. Originally we tried to limit our volumes to a size that can be restored within a 4 hour window... in reality, it is probably closer to 6 hours on some volumes, and we have a couple of "legacy" volumes from pre-multi volume days that are about 150GB. We have tested restores and seem to get around 15-17gb/hour restoring data, depending on the data.

RE: Ndmp vs. Nfs backups.

I have not tested NFS mounted backups versus NDMP direct attach (we use these in a multiprotocol manner, and with NFS mounts you lose the CIFS acls), but I have done backups to remote NDMP storage units using NetBackup. I hope this data is useful. Following is a note I sent to our management earlier this year. This is using NetBackup. The data was collected from NetBackup and thrown through SAS to perform the calculations. Kelly ----- I have been wondering what the affect of local (direct attach drive) versus remote (over the network) backups is on the NetApps. The following reports show that difference... For both reports (Full backups first report, Incr backups second report), the LOCAL is the mean GB/hour for local backups and the REMOTE is the mean GB/hour for remote backups. Where there is no REMOTE it means that there have been no remote backups for that volume. The PERDIFF is the difference between the LOCAL and the REMOTE (REMOTE/LOCAL). The anomalies (where remote is > ) probably means that the first big backup was an incremental backup, which, in reality, is equivalent to a full. Also, there are some volumes that always backup to remote filers... and this is indeed correct. This is on 100ethernet. We are looking at setting up a private GB network for remote backups.

Has anyone tested the speeds of ndmp backups vs nfs? I am looking at three different backup packages, and all have fuctions that will not work with ndmp (archiving, tape duplication, cataloging). I am wondering if nfs is any where near the backup speed of ndmp. If it is close then the benefits may outweigh the speed loss. Right now I am getting about ~8M/s per drive with ndmp which is really nice.

RE: Netapp examples - replication for disaster recovery?

Hello Jim! Yes, at Ericsson in Stockholm we use this setup for disaster/recovery reasons. But we also use the replicated data to take our backups from. I.e we dont have to load our "Frontend Filers" with backup traffic. We have 10 F760's in 5 clusters replicating there volumes to 5 other F760's on another location. 5-6TB of data. We do this twice an hour and see 10-20sec bursts of data going over.

Thanks for responses - I noted that there was little mention of replication. Does anyone out there use replication filer-to-filer for disaster recovery or fail-over? I would like filers at sister sites replicating to one another to allow faster disaster recovery. Does anyone do this? * James A. Klun Sterling Commerce 4600 Lakehurst Ct.
