Re: Lost password
by Gustavo Chaves 17 Jun '00

17 Jun '00

Hi, I want to thank everyone who sent a message trying to help me with my problem. I also want to apologize for NOT HAVING READ your answers before. Yes. I just re-subscribed to the list to send the question and forgot that I had set up a filter long ago to automatically redirect the list's messages to a folder. :-( This was a particularly hard week and I didn't have the time to find out why I wasn't receiving the list's messages. Two days ago I powered down the filer and used a diskete boot to alter the password. On Monday I'll try some of your suggestions so that I don't fall in this trap in the future. Thanks, again. Gustavo.

CIFS file locking problem
by Dave Atkin 16 Jun '00

16 Jun '00

We have a problem with file locking which occurs every few months. We have finally worked out at least part of what is happening. We have a Windows 95 system filestore exported as a read-only CIFS share. There are 1200 or so PCs which access this. Just occasionally when a user launches the Telnet client (Hummingbird) it complains that it can't access its keyboard mapping file. Once this starts to happen, it is the same for every PC. A unix user running as root can't read or do anything to this file either - it gets "permission denied". Yesterday when this happened we used (rc_toggle_basic) lock_dump -f to look at the locks, and we found that a PC appeared to have taken out an exclusive read lock on the file: ========00003a31:0006b48e \95APPLIB\york.hts state=GRANTED mode=Excl-denyA host=OFFICE1 When we found the PC called "office1", it was turned off. The user said it had hung up and she had switched it off. We managed to restore normal service by doing a "cifs terminate -t 0 office1". This raises several issues: 1) If a CIFS client is switched off, is there any sort of keepalive timer on the Filer that closes down open files and locks? 2) Should a PC with read-only access to a filestore be allowed to lock files for exclusive read? Should this perhaps be an option on a qtree or share? 3) This particular application obviously doesn't expect this file to be shared. But could any malicious user take out locks on random important files and freeze the whole network?

RE: Raid Groups and Volumes
by Deborah.Rousseau＠netapp.com 15 Jun '00

15 Jun '00

Here's the scoop on volumes, raid groups, parity drives, hot spares, qtrees, and root: Volume, Raid Groups, Parity, Hot Spares-- ----------------------------------------- A volume by definition will contain one or more raid groups, just like a tray of ice can contain one or more cubes of ice. A raid group can contain a maximum of 28 disks (one parity disk and 27 data disks). The default number of drives in a raid group is 14; that number is considered optimum for performance vs. fault tolerance. (There is data regarding MTTDL (Mean time to data loss) and other performance and mean time measures that prove 14 disks to be the optimum size for raid group.) (NetApp 202 teaches diagnostics and optimization of performance and troubleshooting.) You can setup your 14 - 36Gb drives into one volume. But it would be better to use 13 disks in the raid group and save one disk on shelf as your hot spare. In case of failure, your filer will immediately begin to reconstruct your data to your hot spare. If you have AutoSupport turned on and configured, Network Appliance will be notified by your filer (by email) that a disk has failed and a new disk will be sent to you automatically per our service agreement. Yes, hot spares and AutoSupport are great to have working for you.) Qtrees, security styles, oplocks, quotas, backup-- -------------------------------------------------- You can organize your one (13 drive) volume into qtrees. Qtrees are almost like separate file system partitions. Each qtree can be setup with its own set of properties. To be specific, each qtree can have its own: - security styles (UNIX, MIXED, or NTFS) - oplocks settings (ON or OFF) - quotas for limiting users, groups or limiting the size of the qtree itself - backup and restore schedules Snapshots are volume wide; you cannot take a snapshot of an individual qtree; however, all qtrees will be included in the volume's snapshot. If you setup 2 volumes, you will have a minimum of 2 raid groups and therefore use 2 of your 14 - 36Gb drives as parity drives. Smaller raid groups give you greater protection against a double-disk failure, but slightly less than optimum performance and less storage space. Also, if you reserved one disk as hot spare, it would serve both volumes. Hot spares are global to the filer and can be used in a disk failure of any volume when there are multiple volumes on the filer.) Root-- ------ Some like to setup root as a separate 2-disk volume (parity and data disks). Having root separate helps with backup and disaster recovery and perhaps there are other considerations I don't know about. If root is a separate 2-disk volume, of your 14 disks you would have 2 parity, 1 hot spare and 11 data disks. If you have one volume with one raid group, you will have 12 data disks. There are several other considerations about qtrees, quotas, backup, disaster recovery, snapshots and hot spares to be understood. I would highly recommend NetApp 101 and 202 for comprehensive, hands-on training on fine points such as these. You can find training schedules as well as information on NetApp Certification at http://www.netapp.com/education/#training. Also, a great place to look up technical answers is NetApp's NOW site: http://now.netapp.com/.

Removing vol0
by Brian Hostetter 15 Jun '00

15 Jun '00

I got two filers recently each configured a different way. They each contain two shelves. One had 2 drives used and the other marked spare, which was nice because I could config it any way I wanted. The other has all the drives setup into one 300G volume. Is it possible to pair a volume back down to just the two drives and create another volume? --Brian

RE: Raid Groups and Volumes
by jeffrey.soto＠netapp.com 15 Jun '00

15 Jun '00

Brian, You can have a volume with one or more RAID groups, but not a RAID group with multiple volumes. Disks added to a volume will automatically be added to the first existing raid group until that raid group reaches it's maximum size. After the maximum number of disks per the RAID group "raidsize" is reached, a new raidgroup is automatically created with a parity disk. However, you can create logical partitions on the volume using qtrees. Raid size is set either at volume creation by ; vol create volname [ -r raidsize ] example: filer > vol create vol1 -r 14 or on an existing volume by vol options volname optname optval example: filer > vol options vol0 raidsize 21 ( sets the size of the raid size on existing raid group and subsequent ones for this volume ) >From the manual; The default number of disks in a RAID group (including the parity disk) is 14 ( 2 shelves). A RAID group must contain at least two disks. The largest RAID group size you can create manually is 28 disks. The maximum RAID group size is 52 disks. Using smaller RAID groups reduces disk reconstruction time if a disk fails. Using smaller (therefore, more) RAID groups provides higher reliability by reducing the risk of data loss due to multiple-disk failure. Conversely, configuring with larger (therefore, fewer) RAID groups in a filer uses fewer disks for parity, leaving more disks available for data storage.

See System Administrator's Guide: page 72 Disk Concepts, page 80 Volume Concepts. Raid Groups are subsets of Volumes, not the other way around (for NetApp filers).

RE: Unix group permission and NT access on a filer
by rob.hawley＠netapp.com 14 Jun '00

14 Jun '00

There are a number of important bug fixes and improvements in the security model in 5.3. I would encourage you to upgrade as soon as practical. When you say multiprotocol I believe you mean is what would happen if you started using a more NT style of security. That is another good reason to upgrade. The UNIX portion of the mixed security model was not fully implemented in 5.2. 5.2 fully implemented pure UNIX security as you are currently using. It also implements ACLs from the NT side. It did not fully implement UNIX access to files with ACLs. The NOW articles I cited describe the full implementation that is contained in 5.3. The reference I cited earlier also is a more detailed discussion on the security model then what I could present in an email. I would encourage you to have a look at that document. -----Original Message----- From: Elizabeth Schwartz [mailto:eschwart@genuity.net] Sent: Tuesday, June 13, 2000 9:59 AM To: Hawley, Rob; mstjohn(a)genuity.net Cc: eschwart(a)genuity.net; Muhlestein, Mark; toasters(a)mathworks.com Subject: RE: Unix group permission and NT access on a filer Thanks! We're running 5.2.3P1 I've been talking to the filer admin about upgrading. It sounds like the immediate short-term fix to our problem might be to create a small multiprotocol qtree while we evaluate whether to upgrade the OS and/or change the main qtrees. We need to make sure that we understand all the security implications of changing a qtree from unix to multiprotocol. Do you have anything that shows how the filer stores permission, whatever the filer equivalent of an inode is? (qnode? Wnode?) We were trying to whiteboard how the permissions work. Specifically: 1) I start with a Unix qtree on the filer 2) User directory is created with unix permissions set to 755 3) We then change the qtree from unix to multiprotocol 4) User accesses his directory as a CIFS share 5) User creates a subdirectory and files under his home What will the permissions be on those files? 755? Will they have anything in their NT ACL's? I am under the impression that the filer stores permissions in some "neutral" format which it translates to Unix permission bits or NT ACL's, PLUS has some extra storage for NT ACL's - is that how it works? Also, What happens if you create a multiprotocol file system and then change it later to unix? Is the additional ACL information a) translated, b) deleted, c) stored but not used (so that if you changed it back to multiprotocol again it might still be there?) thanks for any pictures Betsy At 07:06 AM 6/13/00 -0700, rob.hawley(a)netapp.com wrote: >What version of the filer are you running?

RE: Unix group permission and NT access on a filer
by mark.muhlestein＠netapp.com 13 Jun '00

For the release you are running, it is possible to get the group permission checking you want by doing a "cifs terminate" then "cifs setup", and specifying that you want to "enforce UNIX semantics" when asked that setup question. However, there are a lot of good reasons to upgrade to 5.3x, and not just for CIFS-related issues. The links we gave before describe the 5.3 and later security model, and answer your questions. Briefly, in the situation you described, the files would continue to use UNIX-style permissions, since you did not include a step of having the CIFS clients setting an ACL (which sets NTFS-style permissions). See http://now.netapp.com/NOW/knowledge/docs/olio/guides/53_troubleshooting/ind… tml particularly the "Basic Concepts" section.

question about shuffling disk drives around
by David H. Brierley 13 Jun '00

13 Jun '00

I have a situation where I need to replace one of the shelves in an F740 and I want to make sure that what I am planning to do will work ok. I am replacing the shelf because it has some kind of strange fault that causes the second power supply to immediately fail upon power up. I called it in to tech support and after trying a couple of things they ended up shipping me a replacement shelf. Unfortunately, the shelf has already been brought online because the initial failure appeared to be simply a bad power supply and I knew I would get a replacement within a day or so. The machine in question is heavily used and the project does not want me to take the machine down for any longer than is required. What I thought I would do is to shut down the machine and move all of the drives from the bad shelf to open slots on the other shelves (none of the shelves are full yet). I can then remove the bad shelf from the cabinet and install the replacement shelf, this time being careful to do a power up test before connecting the shelf to the filer. Once the new shelf is physically installed in the cabinet I can then shut down the filer, move the drives back to the new shelf, and reboot again. My understanding of the way the filer works tells me that this plan will work but I just wanted to get some feedback before attempting it. The alternative would be to shut down the filer and keep it down for an extended period while the bad shelf is removed and the new shelf is installed but obviously that would involve more down time and I am trying to avoid down time. -- David H.

DLT Problems
by Tom Arlington 13 Jun '00

13 Jun '00

Has anybody seen this ? There's something wrong with the tape drive and/or its configuration on our new Netapp box; the unload-reload command that's supposed to eject the tape and load the next one doesn't seem to work: iron> mt -f urst0a offline Tape device (0b.4) unload/reload failed - please check drive. mt: close of tape urst0a failed The tape ejects from the "DLT1" drive, but doesn't get replaced in the magazine and the next tape doesn't get loaded. This command works properly on our F540s with the smaller 10-tape Overland tape robots. I've talked with both Netapp and Overland and each company blamed the other one. I'm inclined to believe that it's something that I haven't configured properly on the tape drive, but the documentation is less than wonderful about explaining how to configure the auto-advance stuff. I have tried rebooting the tape drive and the netapp box to no avail. Any thoughts? Thanks!

RE: Unix group permission and NT access on a filer
by Elizabeth Schwartz 13 Jun '00

Thanks! We're running 5.2.3P1 I've been talking to the filer admin about upgrading. It sounds like the immediate short-term fix to our problem might be to create a small multiprotocol qtree while we evaluate whether to upgrade the OS and/or change the main qtrees. We need to make sure that we understand all the security implications of changing a qtree from unix to multiprotocol. Do you have anything that shows how the filer stores permission, whatever the filer equivalent of an inode is? (qnode? Wnode?) We were trying to whiteboard how the permissions work. Specifically: 1) I start with a Unix qtree on the filer 2) User directory is created with unix permissions set to 755 3) We then change the qtree from unix to multiprotocol 4) User accesses his directory as a CIFS share 5) User creates a subdirectory and files under his home What will the permissions be on those files? 755? Will they have anything in their NT ACL's? I am under the impression that the filer stores permissions in some "neutral" format which it translates to Unix permission bits or NT ACL's, PLUS has some extra storage for NT ACL's - is that how it works? Also, What happens if you create a multiprotocol file system and then change it later to unix? Is the additional ACL information a) translated, b) deleted, c) stored but not used (so that if you changed it back to multiprotocol again it might still be there?) thanks for any pictures Betsy At 07:06 AM 6/13/00 -0700, rob.hawley(a)netapp.com wrote: >What version of the filer are you running?

Sincere apology for the F330 SPAM

I was naive to not expect a hue and cry from the toasters group re: the message I sent re: the F330 equipment and not recognizing it to be the SPAM that, in hindsight, I guess that it was. I offer my sincere apology to the group. Scott Fischmann Union Computer Exchange, Inc.
