OnCommand CPU report question for 2.x OPM
by Klise, Steve 21 Apr '16

21 Apr '16

>In former versions of DFM or whatever it was called now, I was able to chart individual CPU’s in Performance Manager. Now, I only see an average across all processors w/ 2.x OnCommand Performance Manager. I know I can drop down to the console, and run a sysstat -whatever... but was wondering if I was missing something for OnCommand Performance Manager to see, or graph individual CPUs. Is this an option, or how would I enable, setup? I am running the LOD, and can't see how this can be done... If its not available, that was of value to some of my customers. Steve

NFSv4 clients refused file access by FAS2240
by Ziemowit Pierzycki 19 Apr '16

19 Apr '16

Hi, I have a FAS2240 and used it as an NFSv4 storage for our Linux KVM-based cloud. Few days ago, I noticed a few NFS mounts freezing up. After some investigation, looks like the Linux clients are attempting to get access to files via NFS share and the Netapp appears to be denying it. It appears to happen at random across multiple clients as if we hit some kind of a wall. I found a "lock status -v" command by going to some posts on the internet and after running it, the last line shows the following: Free owners 7; In-Use Owners 8185 Could that be the wall/limitation that's causing my problem? I also learned of a bug in older Linux kernel that creates extra owners and found the client that appeared to have a huge amount of file locks and owners generated. After disconnecting the client and clearing the locks it didn't seem to make a difference. Here is some extra summary from the "lock status -n" command: CIFS: 13 share locks, 0 byte locks NLM: 0 share locks, 1 byte locks NFSV4: 47 share locks, 0 byte locks WAFL: 0 share locks, 0 byte locks TEST: 0 share locks, 0 byte locks FIO: 0 share locks, 0 byte locks FlexCache: 0 share locks, 0 byte locks NG: 0 share locks, 0 byte locks Total Locks: 60 share locks, 1 byte locks Max Locks: 2922432 Total Locked Files: 56 Max Locked Files: 1461216 Any help would be greatly appreciated.

iSCSI booting linux clients
by Chris Good 19 Apr '16

19 Apr '16

Has anyone got any experience using iSCSI luns from a CDOT filer as linux root partitions and would like to share experience/best practice? As background we have lots of Dell blades and it makes sense to us to put cheap SSDs in them as disposable scratch space and to network boot the root FS from our filers. We barely touch the root FS so accessing it over the network doesn't really hurt us and the usage is low enough that the impact on the filer should be negligible. Chris

node and cluster management network architecture, proxy, port forwarding
by Brian Parent 18 Apr '16

18 Apr '16

I'm running into some problems with the network layout on our AFF8020 running CDOT 8.2.3. It seems that using a private layer 2 vlan for node management provides the significant benefit of reducing potential attack sources to servers on that private vlan (where such vlan has a small number of hosts, all with lots of access restrictions, none of which run DNS, ntp, SMTP services). I was hoping to use port forwarding from a server in that vlan to enable things like https, DNS, ntp, and smtp, but have not been successful yet. Before I spend too much more time on it, I thought I should check to see whether others have had success with similar network topology. -- Brian Parent Information Technology Services Department IT Infrastructure Operations Group Workplace, Internal, Research, and Educational Platforms (WIRE) team UC San Diego (858) 534-6090

Netapp CDOT 8.3 and Peerlink software
by Sayla, Mustafa 18 Apr '16

18 Apr '16

Anyone using Peerlink software for File collaboration between offices? We have been using this software to real time sync data from Netapp to a windows server in our remote office. Software worked fine with many years but since January when we migrated our data to CDOT filer and upgrade the peerlink software to a cdot compatible version we have run into issues after issues. Anyone has experience with this software and if not is there another viable option out there for real time sync between netapp and windows server.

Hi folks, Is it possible to create a user in 7-mode without specifying a password, or alternatively disallow password logins for a specific user? My goal is to create a user that must use an ssh key to run CLI commands. Cheers!

Showmount capability in 8.2.2?
by Robert Clark 13 Apr '16

Is anyone aware of a way to check which clients have a particular NFS export mounted, in 8.2.2? I've installed and worked with the showmount command written in python, but it appears to only output the export list. Thanks, [RC]

Listing NTFS style ACLs from unix client via NFS
by John Adams 13 Apr '16

13 Apr '16

Hello, Simple question here.. If a qtree is using NTFS style permissions, and that same qtree is exported via NFS to a unix client... Is there a way to see the NTFS acl's from that unix client? The usual "ls -l" just shows what looks like mode 777. Maybe an open source tool that could be installed on the unix client or something? Thanks.

running SAN on NetApp
by Eric Peng 13 Apr '16

13 Apr '16

Folks, Does anyone have experience with running production workloads on FC-based LUNs on NetApp? Am curious to know how performance of hosting virtual machines (including Exchange, database environments) compares to more traditional block-based SANs (EMC, 3Par, Hitachi, etc), since what I've read is that NetApp's LUNs feature still sits on top of WAFL? We have some native FAS NetApps, along with many N-series rebranded NetApps, but all are run in 7-Mode and using NFS connections. Also, how do you all implement data tiering in your NetApp environments? We are currently using IBM SAN (Storwize/V7000) and this has tiering capability. We'd consider moving some SAN workloads to NetApp if we could get as good SAN performance and also address the tiering capability.

aix san boot lun - no lun id 0
by Rhodes, Richard L. 11 Apr '16

11 Apr '16

Hi Everyone, We have a AIX server that boots from a NetApp (IBM nSeries) for which we need to upgrade AIX. The AIX Admins want me to allocate a alt_boot lun, which they will make the new boot lun after upgrading. Currently the server has two luns: lun show -m LUN path Mapped to LUN ID Protocol ----------------------------------------------------------------------- /vol/v_rsxxxx_boot/q_rsxxxx_boot/lun0_boot rsxxxx 0 FCP /vol/v_rsxxxx_boot/q_rsxxxx_boot/lun1_boot rsxxxx 1 FCP lun 0 = rootvg boot lun lun 1 = non-rootvg lun with paging space If I create a new lun at id 2, we cut over to it and I delete the old boot vol at id 0, I then have a lun id gap - no lun 0. Is this a problem with NetApp storage? (I know we have problems with EMC VNX storage with LUNZ devices if no lun id at 0.)

cDOT 8.2: share NFS volume with CIFS too problems
by John Stoffel 01 Apr '16

01 Apr '16

Guys, I'm banging my head on the wall trying to setup an NFS filesystem on a cDOT 8.2 VServer to also be shared using CIFS. I can see the volume and look at it from Windows, but I can't create any files or directories. Just to make sure I'm not smoking anything, here's what I did: > vol create -vserver flsm-fs01 -vol data310 -size 1t -junction-path /data310 -aggr sas1n2 > vol modify -vserver flsm-fs01 -vol data310 -unix-permissions 777 And here's now it looks now: flsm-ntap1::> vol show (volume show) Vserver Volume Aggregate State Type Size Available Used% --------- ------------ ------------ ---------- ---- ---------- ---------- ----- flsm-fs01 data310 sas1n2 online RW 5TB 4.75TB 5% And I can see it just fine with NFS, etc. My unix username is 'stoffj' and my windows username is 'TAEC_IRV1\stoffj' so it should just map cleanly over using the defaults. > cifs show Server Status Domain/Workgroup Authentication Vserver Name Admin Name Style ----------- --------------- --------- ---------------- -------------- flsm-fs01 FLSM-FS01 up TAEC_IRV1 domain > cifs share show Vserver Share Path Properties Comment ACL -------------- ------------- ----------------- ---------- -------- ----------- flsm-fs01 data310 /data310 oplocks - Everyone / Full Control browsable changenotify I even setup and looked at the "security trace" stuff to try and figure it out. And it complains that my UNIX security is messed up. I've tried to cut'n'paste this info, but all the tabs keep expanding in wierd ways and cause all kinds of havoc here. Here's an example error: n2 1 User: TAEC_IRV1\stoffj Access is denied by UNIX permissions while creating the directory. Security Style: UNIX permissions Path: /john/dir2/New folder Now the interesting thing is that the path shown looks to be at the level UNDER the CIFS share. But it should be ok, right? Here's my permission settings: flsm-ntap1::> file-directory show -vserver flsm-fs01 -path /data310/john/dir2 (vserver security file-directory show) Vserver: flsm-fs01 File Path: /data310/john/dir2 Security Style: unix Effective Style: unix DOS Attributes: 10 DOS Attributes in Text: ----D--- Expanded Dos Attributes: - Unix User Id: 61255 Unix Group Id: 4901 Unix Mode Bits: 2775 Unix Mode Bits in Text: rwxrwsr-x ACLs: - The mode bits are what we want, so that directories and files inherit their group ownership properly. I haven't setup any local users or groups, nor have I done any mappings, since it supposedly will do that for me. On the Unix side we're using NIS to authenticate, and that seems to be working just fine. Any hints? John

NetApp SDK for cDOT: any API call fails if a cluster node is not available
by Momonth 31 Mar '16

31 Mar '16

Hi All, We extensively use NetApp API calls to monitor 7Mode filers, and took the same approach for cDOT monitoring. Here is a very unpleasant discovery: 1. Take one node (or more nodes) *offline*, eg power it off for maintenance. 2. Try to run *any* API call against cluster interface and get the following error: OUTPUT: <results reason="RPC: Port mapper failure - RPC: Timed out" status="failed" errno="13001"></results> It effectively makes your cluster wide monitoring useless. Any ideas? Is it a feature or a bug? Cheers, Vladimir

metro under high latency
by josef radinger 30 Mar '16

30 Mar '16

hi i have a metro cluster (rather old) which is currently responding very slowly. 7-mode 8.1.4 there is only one aggregate per head, filled at around 72% one one head and 79% on the other head. attached is a statit and sysstat -x 1 from one head. i see lots of partial stripes and only several full stripes. i assume this should mean not enough free space, which should imho not be a problem at my aggregates. what is the correct procedure for performing a free space reallocation? i did: * stop all volume-reallocates * disable read_reallocation on all volumes * raid.lost_write.enable off * aggr options aggr0 resyncsnaptime 5 * reallocate start -A -o aggr0 * wait for finish of reallocate * aggr options aggr0 resyncsnaptime 60 * enable read_reallocation on all volumes * reenable all volume-level reallocates my aggregates have options: aggr options aggr0 root, diskroot, nosnap=off, raidtype=raid_dp, raidsize=20, ignore_inconsistent=off, snapmirrored=off, resyncsnaptime=60, fs_size_fixed=off, snapshot_autodelete=on, lost_write_protect=on, ha_policy=cfo, hybrid_enabled=off, percent_snapshot_space=5%, free_space_realloc=off any advice? josef

Transition snapmirror to regular snapmirror
by Basil 23 Mar '16

23 Mar '16

I am trying to migrate a replicated volume to CDOT, but I can't use 7mtt. My plan is to set up a transition snapmirror and do the cutover manually. I can't start the regular snapmirror of the CDOT transition snapmirror target, though. I get "Using a transition volume as a snapmirror source volume is not supported". I have a long outage window, but would prefer to pre-seed the mirror of the new volume. What would you folks suggest?

Moving shelves with root aggr and root vol (7-mode) from one Filer to another
by Martin 22 Mar '16

22 Mar '16

Hi, I have one 7-mode Filer that I will be decommissioning which has data on it I need to migrate to another 7-mode Filer. We don't have space to mirror the data to the new Filer, want to reuse the shelves on the new Filer and this is a quicker cut over. The four DS4243 shelves have a single aggregate (aggr0) with various volumes on it (exported via NFS) including the root volume for the controller (vol0). I found the KB on moving shelves and aggregates between controllers but it doesn't mention what to do about a Filer that has vol0 and root aggr on the shelves. My plan is: 1. Disable disk auto assign on both source and destination Filer on both controllers options disk.auto_assign off 1. Reboot the source controller into maintenance mode 2. Offline aggr0 aggr offline aggr0 3. Uknown the disks on the shelves on the source controller disk assign disk_name -s unowned -f 4. Shutdown the Source Filer and power off along with shelves 4. Power down the destination Filer and add SAS card to new Filer (not enough SAS ports for new loop) 5. Physically moves shelves from source Filer to destination Filer 6. Cable shelves and change shelf IDs along with a powercycle to ensure shelf IDs don't conflict 7. Assign the disks on the new Filer disk assign disk_name 8. As the aggregate is aggr0 and new Filer also has aggr0 it gets renamed to aggr0(1) and foreign 9. Check the status of the new aggregate aggr status aggr_name 10. Rename the new aggregate from aggr0(1) to aggr1 aggr rename aggr0(1) aggr1 11. Online the aggregate on the destination Filer as it is longer labelled as foreign aggregate. aggr online aggr1 12. Check the aggregate status on the destination Filer aggr status aggr1 13. Export the volumes on the destination Filer via /etc/exports and exportfs -r -- View this message in context: http://network-appliance-toasters.10978.n7.nabble.com/Moving-shelves-with-r… Sent from the Network Appliance - Toasters mailing list archive at Nabble.com.

disk ownership question
by Mark Flint 22 Mar '16

22 Mar '16

Hi list. I have a 3170 running 8.0P1 7-Mode, and am having a problem with auto-assignment of disks. The unit reports that it can’t do auto-assign, because not all of the disks on the loop are owned by the same controller. I was under the impression that software ownership made that unnecessary (you can laugh), but it seems not. KB from 2014 says the same thing. So, question is, has anyone done anything like this (had to reassign a shedload of disks) to make auto-assign work, and could they pass any info on how I can fix this please? Thanks, Mark

7Mode junction-path style on cDOT
by Momonth 18 Mar '16

18 Mar '16

Hi, I wonder if it's possible to employ 7Mode mount point behavior on cDOT NFS SVM? An example: 1. I create a volume "share_01" and by default it shows up as "toaster:/share_01". 2. I'd like to access it as "toaset:/vol/share_01" So, my question is how to add "/vol/" to its junction_path? Cheers, Vladimir

Dealing with a really large number of files in a single directory
by Edward Rolison 17 Mar '16

17 Mar '16

I've got a directory on an NFS server. I think it's been filling up with log files, and may be in excess of a million. (ls -d shows me a 350MB rather than the usual 4k). strace -fTt ls -1 -f is stalling on 'getdents' system call. I assume it'll complete eventually, but ... well, the 'leave it and wait' hasn't yet. Does anyone have any good tricks on a filer for helping me tell that a) this directory is in fact, absurdly large and b) starting to retrieve filenames so I can delete/move them in sensibly sized baches? (I'm wondering if a filer-side ls is going to help or hinder, for example).

missing NFS exports after controller reboot
by Eric Peng 10 Mar '16

10 Mar '16

This is a bit of a quirky issue, wondering if anyone has come across this before? We are hosting a vFiler on a 7-mode array. The other day we had a controller reboot, and it seems after the HA-failover that the NFS exports of the vFiler somehow went "missing" - the /etc/exports file was missing most of the entries. We ended up having to manually recreate the entries, but am wondering if anyone has come across any type of quirky behavior such as this? We are running 8.1.4 P1 on this array, it is hosting many CIFS & NFS shares, as well as VM workloads. We are on 3rd party support now, so cannot open a ticket with IBM Support (rebranded NetApp).
