Tech ONTAP Podcast: Now powered by NetApp FlexGroup volumes!

If you’re not aware, I co-host the Tech ONTAP Podcast. I also am the TME for NetApp FlexGroup volumes. Inexplicably, we weren’t actually storing our podcast files on NetApp storage – instead, we were using the local Mac SSD, which was problematic for three reasons:

  1. It was eventually going to fill up.
  2. If it failed, bye bye files.
  3. It was close to impossible to access unless were were local to the Mac, for a variety of reasons.

So, it finally dawned on me that I had an AFF8040 in my lab, barely being used for anything except testing and TR writing.

At first, I was going to use a FlexVol, out of habit. But then I realized that a FlexGroup volume would provide a great place to write a bunch of 1-400MB files while leveraging all of my cluster resources. The whole process, from creating the FlexGroup, googling autofs in Mac and setting up the NFS mount and Audio Hijack, took me all of maybe 30 minutes (most of that googling and setting up autofs). Not bad!

The podcast setup

When we record the podcast, we use software called Audio Hijack. This allows us to pipe in sound from applications like WebEx and web browsers, as well as from the in-studio microphones, which all get converted to MP3. This is where the FlexGroup NFS mount comes in – we’ll be pointing Audio Hijack to the FlexGroup volume, where the MP3 files will stream in real time.

Additionally, I also migrated all the existing data over to the FlexGroup for archival purposes. We do use OneDrive to do podcast sharing and such, but I wanted an extra layer of centralized data access, and the NFS mounted FlexGroup provides that. Setting it up to stream right from Audio Hijack removes an extra step for me when processing the files. But, before I could point the software at the NFS mount, I had to configure the Mac to automount the FlexGroup volume on boot.

Creating the FlexGroup volume

Normally, a FlexGroup volume is created with 8 member volumes per node for an AFF (as per best practice). However, my FlexGroup volume was going to be around 5TB. That means 16 member volumes would be around 350-400GB each. That violates the other best practices of no less than 500GB per member, to avoid too much remote allocation. While my file sizes weren’t going to be huge, I wanted to avoid issues as the volume filled, so I met in the middle – 8 member volumes total, 4 per node. To do that, you have to go to the CLI; System Manager doesn’t do customization like that yet. In particular, you need the -aggr-list and -aggr-list-multiplier options with volume create.

ontap9-tme-8040::*> vol create -vserver DEMO -volume TechONTAP -aggr-list aggr1_node1,aggr1_node2 -aggr-list-multiplier 4
ontap9-tme-8040::*> vol show -vserver DEMO -volume TechONTAP* -sort-by size -fields size,node

Automounting NFS on boot with a Mac

When you mount NFS with a Mac, it doesn’t retain it after you reboot. To get the mount to come back up, you have to configure the autofs service on the Mac. This is different from Linux, where you can simply edit the fstab file. The process is covered very well in this blog post (just be sure to read all the way down to avoid the issue he mentions at the end):

https://coderwall.com/p/fuoa-g/automounting-nfs-share-in-os-x-into-volumes

Here’s my configuration…. I disabled “nobrowse” to prevent issues in case Audio Hijack needed to be able to browse.

After that was set up, I copied over the existing 50-ish GBs of data into the FlexGroup and cleaned up some space on the Mac.

ontap9-tme-8040::*> vol show -vserver DEMO -volume TechONTAP* -sort-by size -fields size,used

DEMO TechONTAP__0008 640GB 6.25GB
DEMO TechONTAP 5TB 53.29GB
9 entries were displayed.

Then, I configured Audio Hijack to pump the recordings to the FlexGroup volume.

Then, we recorded a couple episodes, without an issue!
