Suggestions from McAfee are that the scanners become too busy and when that happens, they drop off line and reset themselves. However, performance indicators on the scanners don't indicate any problems: CPUs almost idle, no disk I/O, very little network activity. From a filer stand-point, they're practically idle: CPU time averages less than 20%, network and disk I/O is minimal. I'd like to hear how some of you have your McAfee environments configured and what (if any) issues you've had similar to this one. As usual, much thanks in advance!

RE: Switching from NIS auth to Windows Domain
by Hill, Aaron 02 Feb '05

I believe the usermap.cfg is your ticket. But only if I am understanding your issue correctly. If your usernames are unique, i.e. only 1 fred will ever open a CIFS session on a particular filer, then you should be able to do something like this in the file with great success; <DOMAIN>\* == * <DOMAIN2>\* == * <DOMAIN3>\* == * Etc. etc. Essentially, ESERVICES\FRED will map to unix fred, but so will DONKEYDOMAIN\FRED. So your problem will be duplicate ID's. The == specifies a two-way mapping, i.e. unix fred will also map to the first domain that is found in the list that has a "fred/FRED". If you omit the ==, it will be implied by default. i.e. <DOMAIN>\* == * is the same as saying <DOMAIN>\* *. If youi want the mappings one way, use => or <= . The usermap.cfg parses from top to bottom, so the first match will be the mapping that is used. I do not know if there is a limit to the number of entries. If you need to enter many hundreds of domains, this may become an issue and you may see some slow authentication. For more details on this you will need to talk to a NetApp engineer. There may also be a way to do it thus; *\* == * And combining the cifs.search_domains option to specify the order that the domains are searched. If you omit this setting, they are randomnly searched. So, it may be wise to place your highest populated domains at the top of the list to speed up authentication. Once the mapping cached by the filer, things should move through a lot faster. Even if you have duplicates, my guess is that there will not be many. Particularly if you have good practices regarding the creation of user accounts. If there are, you simply disrupt a "few" users by modifying their user names and associated data. If this is 10% of your 30,000 users it will still be a lot of work, but a lot less than the full 30,000 coming down on you. Test it out, let me know how it goes. Good luck!

Right now when you "map network drive" and you fill in the username field in the dialog box, you do not need to specify a domain name. If you enter "fred" in the dialog box then your PC supplies a domain name for you automatically. Because we are using Unix style login for CIFS, the filer strips off the domain name and looks up your account using just "fred". However, once we switch to Windows domain auth, if you enter just "fred" in the username field, and if your PC supplies something other than "eservices" for the domain name (very likely here) then your username is incorrect and you cannot login. You don't even get to the point where your Windows domain credentials are mapped to your Unix UID, etc. Our user education problem is teaching 30,000 people who currently enter just "fred" to start entering "eservices\fred" instead. I was hoping that there might be a magic option on the filer that would help us avoid this.

Switching from NIS auth to Windows Domain
by Steve Losen 01 Feb '05

01 Feb '05

We have been using filers to store users' home directories since 1997. We started out with NFS on Unix and added CIFS access later. We have about 30,000 user accounts. We have always used NIS authentication for CIFS so that folks have the same password on Unix and CIFS. But we have been unhappy with the passwords going over the network in clear text. We have finally gotten funding for enough Windows client licenses to give all our users accounts in a Windows domain, so we want to switch our filers to Windows domain auth. This is going to cause us a serious user education problem. Currently it does not matter what domain a CIFS user specifies because the domain name is ignored when mapping a to a NIS user. For example, BOGUS\fred maps to "fred" and MYDOM\jane maps to "jane", etc. Right now when "fred" does a "map network drive" he just enters "fred" for his username. His PC supplies the windows domain, whatever that may be. Some folks login to local departmental domains. Some do local Windows logins, etc. Right now that doesn't matter because the filers ignore the domain name when mapping to a NIS username. But that will suddenly change when we switch to Windows domain auth. Fred will suddenly be required enter "ESERVICES\fred" instead of just "fred". Does the filer have any option where it "knows" that no matter what domain name the user supplies, in his heart of hearts he really means "ESERVICES" ? That would save us an awful lot of calls at our help desk when we cut over. By the way, we don't know in advance what domain name a user may supply. Many of them appear to be whatever name the user gave his PC. Steve Losen scl(a)virginia.edu phone: 434-924-0640 University of Virginia ITC Unix Support

RE: Switching from NIS auth to Windows Domain

If the user names are the same on the Windows side and the Unix side, regardless of what Domain those users are a part of, you shouldn't have any issues with the drive mappings. As defined in the "System Administration - File Access Management Guide for Data ONTAP 6.5" pg.93, these are the steps taken when a CIFS session is requested: - It searches the /etc/usermap.cfg to see whether an entry matches the user's Windows domain name and user name. - If an entry is found, Data ONTAP uses the UNIX name specified in the entry to look up the UID and GID from the UNIX password database. If the UNIX name is a null string, Data ONTAP denies access to the CIFS user. - If an entry is not found, Data ONTAP converts the Windows name to lowercase and considers the UNIX name to be the same as the Windows name. Data ONTAP uses this UNIX name to look up the UID and GID from the UNIX password database. If that doesn't work, you also might want to look into setting up the usermap.cfg file in such a way that will work in your environment.

[SUMMARY]: Archiving, R200 and SnapVault.
by Ngoh, Clarence 31 Jan '05

31 Jan '05

Thanks to the following people who replied: Aaron Hill Bill Holland It turns out that at the end of the day, using SnapVault was not the most straighforward solution. We simply wish to copy an EOM (end-of-month) snapshot to the R200 temporarily to conserve snapshot space on the production filer whilst getting our backup problem fixed. The use of Snapvault did not meet our need to duplicate the whole volume when compared to how how SnapMirror duplicates its volume. One of the significant difference between the two is that the basic unit in Snapvault is NOT the valume, but the qtree. As such, a transfer must be made to replicate each qtree. It was also pointed out that complexity is added to the restoration process because a snapshot from SnapVault is essentially restored and Snapvault has its way of doing its thing. A third point of complexity is configuring Veritas NetBackup to backup the snapshot - an option that we are not willing to experiment with. So, what are we doing? We have two volumes that are running low on disk space on the Production filers. We have created two volumes on the R200 to reflect those on production and we are snapmirring these across. Once the data is replicated, we remove the older EOM snapshot to free disk space. Backups of the snapshots are then done via 3-way-NDMP. A much more simple and elegant solution.

RE: Solaris patch 118463-01, NetApp filers, and du
by Barnes, Simon 28 Jan '05

28 Jan '05

Hi Chris, Sorry it's taken me a while to reply. I'm very interested in your take on the Solaris 9 du patch, as I was instrumental in its creation. One of the customers I work with at NetApp had noticed that du returned a "cycle detected" error in Solaris 9, whereas it had not in Solaris 8. (Incidentally, I'm told Solaris 10 doesn't return this error either). With the help of my customer and Sun, we were able to identify the code change which had provoked this behaviour. As I understand it, Sun's patch does indeed, as you say, revert to the earlier Solaris 8-like behaviour, in that it ignores the error condition rather than fall over when it hits it. (Although Sun themselves are far better placed to comment than I am). This is what the customer in question wanted from the patch. Unfortunately I will be out of the office all of next week (back on 7th February), but I'd be happy to discuss this further with you when I return. My customer, I'm sure, would also be most interested to hear what you think of this solution, as so far he appears to be the only one to have reported this issue to us - unlikely as that sounds. Please feel free to drop me a line or give me a call. Regards, Simon.

Maybe I will have more luck here. A patch 118463-01 was released by Sun for Solaris 9 du(1) on 2004-12-06. It "fixes" 5068958 Solaris 9 du exits with "cycle detected" The description of this on SunSolve includes the following: | Description: | | Solaris 9 du exits with: | | du: failed for /: Cycle detected from XXX to XXX | | when a hardlink in the filesystem is detected. While at first sight | this seems reasonable behaviour due to the potentially harmful nature | of hardlinked directories, there is a genuine need to handle this in a more graceful way. | | One such example comes from using a NetApp File Server with snapshots. | The NetApp server exports snapshot heirarchies with file ids (aka | inode | numbers) which appear to be identical to existing directory file ids. | | While this is an implementation issue concerning the interaction | between Sun's NFS clients and NetApp File Servers, in the interests of | interoperability, the Solaris 9 du should simply ignore directories | with apparent duplicate inode numbers. I wonder what other users of Solaris in conjunction with NetApp filers think of this? Personally I thought the change in Solaris 9 was positively beneficial ... an error (even if obscurely expressed from the end-user's point of view) rather than a totally misleading result. It might have been useful if the patch had been to produce warning messages "I've seen this directory inode number before, I'm leaving this [snapshot] out of the space calculation altogether" and carry on with the rest of the tree. (One might think that this was what was implied by "simply ignore directories with apparent duplicate | inode numbers".) But it seems that it actually restores the Solaris 8-and-earlier behaviour, in which you get a total which is a naive sum over all snapshots, which is never (well, hardly ever) meaningful.

NFS hangs from linux clients
by Gil Freund 28 Jan '05

28 Jan '05

Hi, We have three Debian systems (two with 2.6.x Kernel and one with 2.4) using a NetApp 720 (6.5.3) as an NFS server. On two occasions in the last two weeks, when one of the Linux hosts tried to mount a file system from the netapp we got the error: Host nono not responding. (nono being the filer name) From that moment, no action could be preformed from any of the Linux hosts on the netapp. We see not errors in the log files of either the Linux nor the netapp. Other functions (CIFS, NIS and DNS lookups) continue with not issues. Attempting to stop and start the NFS service on the netapp did not have any effect, neither did rebooting the clients. The only workaround was rebooting the filer, after which all NFS operations resumed without a problem. I have started a trace on NFS, but did not get the same hangup yet. Did anyone encounter a similar situation, or alternatively can advise on where and what to check? Thanks Gil

Archiving, R200 and SnapVault.
by Ngoh, Clarence 28 Jan '05

28 Jan '05

G'day toaster folks, Our backups in Lidcombe are having issues completing its backups - the cause is yet unknown. As a result of our EOM backups not completing successfully, it is eating into our snapshot space. We have raised a case with NetApp and we are trying to isolate the root case of the problem. I am not after suggestions to fix this at the moment. Rather ... We have just purchased a R200 for achiving purpose and we are thinking of utilising this to alleviate the issue we are having. We wish to dump some of the EOMs to this box and backup to tape when we resolve the backup issue. Our scenario is common ... A production site and a DR site. We backup our EOMs at the DR site. We are wondering if the process is as simple of copying over the EOM snapshots from the DR filer to the R200 via SnapVault and configuring our backups (Veritas NetBackup) to backup from the R200 to cassette. Question : From what I have read, backups to cassette can be done straight from the R200. Any real life experiences to share? Are they any caveats that we should be aware of? Sorry if this question seems somewhat simple -- I am still ploughing through a pile of whitepapers at the moment, but because this issue is somewhat urgent, any suggestions would be much appreciated.

SNMP CPU queries suddenly returning zero
by Gavin Kelman 27 Jan '05

27 Jan '05

Hi, I recently started graphing CPU busy time with SNMP and it worked fine for a few weeks, and then all of sudden one day, it always returned 0 and has done ever since. I suspect rebooting the filer would bring the SNMP CPU reading back to life, but I was wondering if anyone had a better idea... I'm running NetApp Release 6.5.2R1P9 on an F940 and using the following command to get the information: snmpget netapp public -m NETWORK-APPLIANCE-MIB.txt \ NETWORK-APPLIANCE-MIB::cpuBusyTimePerCent.0 Telneting to the filer and running "sysstat" returns normal (non-zero) CPU usage information. Ideas? Cheers, Gavin. -- Gavin Kelman gavin(a)metahusky.net

The man page for the vol command specifies that one can use suffixes of d/m/y for days/months/years when specifying the volume retention period parameters. A Snaplock Enterprise volume doesn't let an admin "expire the volume" but it does let an admin destroy it. >From a Linux system, you can see the atime (access time of a file, which is overloaded to keep the retention date if the file is on a WORM volume) by mounting the file system and running "stat <filename>" >From Solaris, mount the file system and run "ls -lu <filename>" Jeff -----Original Message----- From: aaron hirsch [mailto:aaronh@uptime.net] Sent: Thursday, January 27, 2005 7:01 AM To: toasters(a)mathworks.com Subject: RE: SnapLock Questions Rene, SnapLock comes in two versions, Compliance and Enterprise.

DFM 3.1 Events
by Holland, William L 26 Jan '05

26 Jan '05

Anyone found a way to stop DFM 3.1 from recording certain events? For instance, we have AutoSupport turned off due to security configuration policies. However, every few hours the filers dutifully report that AutoSupport is turned off and try to cajole me with all the benefits of turning it on. I know it's off, I purposefully turned it off, stop notifying me about it. I don't want to see this event in my DFM events. Another example is when CIFS event log is full and it creates another one - I get LOTS of these every day. I don't care about them. Only tell me if you couldn't create one. These two events alone spread across 3 filers, I have gathered approximately 1700 events in the week I've had DFM running. I don't want these events taking up space in my database, I don't want to filter through them every day looking to see if there is some event worth my paying attention to that I may not have yet established an alarm for. In short, by being inundated with informational events that I don't care about, the usefulness is being diluted.
