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). Thanks, Eric Peng | Enterprise Storage Systems Administrator Esri | 380 New York St. | Redlands, CA 92373 | USA T 909 793 2853 x3567 | M 909 367 1691 epeng(a)esri.com<mailto:epeng@esri.com> | esri.com<http://esri.com/>

OCPM 2.1 RC1 Client Cert?
by Carl Howell 09 Mar '16

09 Mar '16

Trying to do a fresh install of OCPM 2.1 RC1, but when I attempt to connect to it, it is demanding a client certificate that I don't have on any of my workstations. Is there a way to disable this? Thanks, --Carl

Anyone have a recommendation for a global 3rd party support vendor?
by Ilderton, James 04 Mar '16

04 Mar '16

We've got FAS systems across the globe, some of which are already EOL/EOS. Even the ones that are not, after year 3 NetApp SupportEdge gets crazy expensive. We have used 1 vendor, but I'd like to hear if anyone else has a good experience with one we could work with also. Thank you.

widelinks and catastrophic deletes?
by Rue, Randy 02 Mar '16

02 Mar '16

Hello All, We're looking at using NetApp's Widelinks features to map symbolic links such that SMB-connected users can click through to other UNCs (on different systems) regardless of whether the system they're connected to has a mount to the other system. I've never taken a close look at it before today and it feels like magic. You more or less map a regex so that any link that starts with (say) /mnt/foo/bar/ and has a counterpart on a separate SMB server i.e. \\good_times\life-is-good\<file:///\\good_times\life-is-good\> will translate along the lines of /mnt/foo/bar/giddyup/ = \\good_times\life-is-good\giddyup\<file:///\\good_times\life-is-good\giddyup\>. But I also found something really scary. If from a linux machine I go to /mnt/foo/bar/ and delete the symlink "giddyup" all is well, I just delete the symlink. But if from an SMB client I navigate to \\good_times\life-is-good\<file:///\\good_times\life-is-good\> and delete giddyup I don't remove the link, I delete all of giddyup from the target. Found this on NA's site: "Note that if a client attempts to delete a local symbolic link (absolute or relative), only the symbolic link is deleted, not the target file or directory. However, if a client attempts to delete a widelink, it might delete the actual target file or directory that the widelink refers to. Data ONTAP does not have control over this because the client can explicitly open the target file or directory outside the storage system and delete it." I've tried changing the NA CIFS Share's properties so that symlinks are RO, tried changing the properties of the actual presented link/folder to RO, and tried changing the top level of the target folder to RO, with no difference in behavior. Anybody else using this feature? If so, how are you doing it safely?

NetApp API authentication
by Edward Rolison 01 Mar '16

01 Mar '16

Having started to review some of our filer automation scripts, I'm starting to look in a bit more detail at the API. My first conclusion is - the perl SDK doesn't actually seem to do anything much - it seems to be a reimplementation of LWP and and XML Parser. Given I have LWP and XML::Twig installed, and am making API calls just fine, is there anything I'm missing here? Aside from that though - authentication types. I currently use ssh public-private key pairs, in a trusted account on a management station to enable 'doing stuff' with filers. It _looks_ like my only option with the API is to create a designated service account, and assign permissions... and then embed a username and password in a script somewhere. That just doesn't sit well with me - I like what ssh-agent will do in 'unlocking' key files, and I don't like embedding (potentially privileged) usernames and passwords ... anywhere. Does anyone have a better solution than a couple of designated API users (privileged and read only) with a file somewhere embedding their username and password? Does anyone have a better approach?
