Either there is something wrong with the formatting of the information that you pasted, or you don't have any qtrees. Could you please somehow either fix the formatting or explicitly tell us the name of the volume or volumes? Deleting a qtree just removes the qtree and the data that in that qtree.  Those blocks well be held in snapshots until they "rotate out" if you use scheduled snapshots. I can't really tell what is going on.  Having multiple snapvault destinations on one volume can't be good idea either, but like I said, the formatting is a mess. ... View more

The chances of running into a bug are pretty even for almost all functionality you use on NetApp so that shouldn't be a criteria for using reallocate or not.  I've used it for probably more than 4 years on lots of different platforms and load configurations without hitting any bugs that caused a panic.  Other panics have occurred, but that is another discussion. I don't think we need to scare anyone about panics and reallocate.  If you have never panic'd a NetApp, then you just aren't using it right, hehe. ... View more

The example that I posted will get you a "backup" link.  The examples that you posted will get you blocked interfaces.  You can't add e0d to an existing ifgrp if that configuration isn't supported by the switches, i.e. on two separate switches that can't build etherchannel/link aggregate groups.  You can't just pack e0d into another ifgrp and force them together either. I'm not sure how you think you solved this, but with the configuration attempts that you posted, you are unlikely to have success. ... View more

Hi, Basically, the ability to run port aggregationg/etherchannel is also dependent upon the switch supporting it.  Since you are running an active aggregation of multiple links over more than one switch, the switches have to support etherchannel/port aggregation over multiple switches.  There are a limited number of switches that support this.  The end result is, as was already posted, the switch spanning-tree exchanges notice the same MAC address on more than one switch and to avoid loops, one or more ports will be blocked on the switch. If your switches don't support link aggregation over multiple switches, you need to set up 2 levels of link aggregation: one "ifgrp" with the original 3 interfaces and then a "failover" ifgrp above that in which you have one passive port for failover and 3 active ports, like this: ifgrp create lacp ifgrp1 -b ip e0a e0b e0c ifgrp create single s_ifgrp1 ifgrp1 e0d ifgrp favor ifgrp1 Otherwise you basically have to fix your choice of switches or switch configuration to support what you are trying to do. ...

Hi, You probably need to read the system documentation to help you understand what a qtree is. Basically, at the very least, you will delete the few bytes that the qtree needs within the system.  At the most you will remove all of the data residing under the qtree in the filesystem. Some more information (examples if not excerpts) would be helpful in giving a more complete picture of what you are proposing and additionally, to get you correct answers. ... View more

Hi, The point I tried to make at the very beginning is that your question is not clearly stated.  Simply by looking at the question, I was pretty sure that you did not understand some of the underlying terminologies and technologies. 1. Taking a CIFS share offline does not delete it. 2. Deleting a CIFS share (which you haven't done) doesn't delete the data, just the CIFS share (a pointer to a directory) 3. Have you actually listened to the suggestion that you create a share pointing to /vol/volStaging?  And then try to delete the directory (or as you call it, folder). I think your life would probably be a lot easier with fewer shares anyway.  Your backup/staging script can surely find \\<netapp>\staging\$machine_name   instead of \\<netapp>\$machine_name. The "directories" under /vol/volStaging  would probably be more flexible as qtrees.  In the end, you aren't going to get the help you need until you ask more specific questions and understand the terms and technology. ...

I'm not entirely sure what you mean by "the information" "options" settings are kept in a file (actually a number of files) in the /etc directory on the filer.  These files are not meant to be edited. Manual changes to the files will be overwritten unless you are running in a limited operating mode. Your NTP problems are most likely fixed in 8.0.1P3. ONTap isn't a linux OS... in case that isn't apparent. ... View more

Hi, Generally you can run reallocate on any volume.  NetApp says the system will measure the filesystem and try to avoid reallocating if it will impact performance negatively.  Now, that isn't something that I have tested for myself.  Generally, your corner cases come in combination with deduplication because they can work "against" each other as the two processes have different goals: space saving vs. performance/defragmentation. Here, again, some understanding of how both work can help you to decide if you should run reallocate on a scheduled/incremental basis.  When you add a few disks to an aggregate, for example, it may very well be a good idea to run a full reallocate job on your deduplicated volumes as well to insure performance across all disks.  Very highly deduplicated volumes and very low deduplicated volumes probably won't suffer much from reallocate.  Those that are in-between are more a matter of experience.  The type of access pattern (frequent/infrequent, random, sequential, high/low change rate) will also be a factor to consider. You will have more problems setting up a sensible schedule and monitoring the results than deciding what you are going to reallocate.  Unfortunately, NetApp's new features are rarely accompanied by any sensible way of managing them.  Reallocate has existed for over 5 years now and still there is no way to monitor results other than analyzing the logs. Good luck. ... View more

Athough I think the answers to your questions were probably already answered in the preceding discussion: 1. No. There may be ClusterMode/GX configurations that uses plexes in ways that I am not familiar with. 2. A plex contains one or more raidgroups: data and parity disks belonging logically together for purposes of data redundancy. ... View more

Hi, If you want to create a CIFS share that is meant to be accessed only by a machine account, you can map the IP address of the server to a local account on the filer in usermap.cfg and then add that user with useradmin and finally add full control for that user on the share.  You may want to add other rights to the share for administration of files.  I found it helpful to make the shares hidden to reduce the chance of others accessing the file. We've done this for Notes storage on a set of filers for a lot of years.  It seemed like a hack at the time, but it has been suprisingly stable. 10.10.10.10:"" => sccmuser      (a backend storage IP subnet to limit access via IP spoofing can be a good idea) useradmin user add sccmuser -g administrators -c "SCCM server"  (or some other more limited group) cifs access <sccm_share> sccmuser Full Controll Something like this should get things rolling. The documentation says that machine accounts should be able to access the data.  Not sure if you've looked at that specifically or not. ... View more

I think you can pretty safely assume that this is a documentation oversight.  7.3.5 broke in spectacular ways.  7.3.5.1 is just 7.3.5P1 + 2 smaller patches.  Running patch levels after a release is probably no less risky than running the release itself, in my (humble) experience and just as supported, for what that is worth.  I'd say you're good to go.  You might even want to go 7.3.5.1P2 or better.  Looks like there is some general brokenness in FlashCache starting to show up. ...

This isn't a NetApp issue at all.  The fact that we all have to live with gazillions of GB of unstructured data in the modern world is largely the result of Mickeysoft's marketing train and the fact that everyone has been brainwashed to think in a PC centric world.... NAS shares are just a bigger garbage can (dustbin) than ye' ole C: drive... Now that fact that one can dump nearly endless amounts of information on largely unrestrained central file storage systems in the same unstructured manner that Bill Gates cursed us with under DOS is hardly NetApp's fault.  Indexing files on a per server basis helps very little for large enterprises anyway, so basically it is still a SOHO solution for a SOHO operating system. Sharepoint is a start in the right direction, but again, so hoplelessly imature and featureless that it will be years before it helps with any sort of major data structure changes. NetApp does many things infinitely better than what Microsoft has managed to acquire/buy and has done it much longer.  Frankly, I've never seen a directory structure that everyone thought was intuitive and at the same time no huge outcries for being able to search everything.  Most people use their mailbox to find their way back to whatever was important, unfortunately. Enterprise level archiving and search systems will probably have to play a larger role in the future as well since we are going to be stuck with the legacy of the PC world for a long time, but the closed proprietary formats make it all just that more difficult and finding a hundred files of the same name is hardly useful.  Again, this is an MS-created problem (like virus, insecure windowing systems, hopelessly immature mail servers, inseparable GUI's for management, etc), not really something that one can blame NetApp for. Getting rid of windows file servers saves infinite work with licenses and patching and virus scanning and makes backup and redundancy a management dream. I, for one, am happy that I don't have to deal with the brokenness of Windows files any more than keep virus scanning running.  ... View more

I think you are going to have to try to ask your question in a way that is more understandable. Try to include a bit of information about how it looks on the filer... the volume, qtree... cifs share and what commands you have used.  (the CLI is really very effective) Try to get familiar with the system documentation on NOW. You will probably get more help if you ask the question a bit more clearly. ... View more

Hi, You probably should read the system documentation for your release, specifically the sections on CIFS administration. Basically, you just need to re-run 'cifs setup' to change your domains.  You need to be the "root" user and have an AD user that has enough permissions to add machines to the domain and some information on what container they will go into, etc. The real problem starts if you haven't migrated your users as-is (no SID changes) to the new domain.  You then have to go through and change the rights and ownership on all of your files to reflect the changes in user and groups. Good luck. ... View more

What makes you think that there should be an ntp.conf file? The configuration for time syncronization is the same as always.  The fact that the underlying time-keeping software may now be a real ntpd instead of the old java hack doesn't mean the documentation for the system suddenly became worthless. Just add some servers, set the protocol (think only ntp works), and turn it on. The ordering of the servers is something that I am not sure is of any consequence. ... View more

Well, I hate to belabor the point or be this confrontational, but you are wrong, at least about me being wrong, but your refutation doesn't ever actually meet what I am talking about. This is easily demonstrable. 1. Setup a unix/linux host with 2 IP's in the same subnet and one IP on a NetApp in the same subnet.  Create an export rule for just one of the IP's on the unix host.  Try to mount the export a few times.  At random times it will fail. 2. Put a NetApp filer in a different subnet.  Setup 2 IP's on the filer in that subnet.  Setup firewall rules that allow for snmp requests to one of the interfaces.  Run snmpwalks for a while.  It might not fail right away, but at some point it will fail.  The NetApp will answer from the IP/interface that is not allowed. 3. Just sniff the traffic from example one.  Even add another IP on the NetApp side to make it even more interesting. But basically, there is no difference between interfaces on the same subnet.  If the OS chooses to initiate traffic from any one of them, it is behaving correctly, and to a point deterministically, that is, it is following routing rules, it is behaving correctly, but not predictably for a specific interface/IP.  The OS just makes the choice. This will basically work with any 2 interfaces in the same subnet.  I guess I wouldn't be sitting here writing all of this if you had ever tried this.  Even if I had 2 interfaces on the same subnet on this laptop, I couldn't, without some source route hack, determine which of them would contact this website.  The OS would just choose an IP, because they have equal value in reaching the default gateway, because they are in the same subnet. Basically, you are avoiding direct refuation.  That connections have source and destination IP's is defined, but that is hardly the point here.  Qualifying your arguments with "quite" and "pretty much" does seem to detract a bit from your contentions as well. Anyway, like you said, we are wondering off topic here. ... View more
