Looking for hunting advice (MacOS X and NFS mounts)

$

By Peter Devlin -

Apologies up front for a blatantly brain-sucking post.

We have just put together a satellite facility wherein one of the artists (a genuine power user, an endangered species) works on MacOS X. He's experiencing issues which I have been unable to grokk as my Mac knowledge / expertise expired about 7 years ago. I know there are Mac heads on this list so I'm hoping someone can give me the benefit of their own more relevant experience.

The nub of the problem is automounting an NFS share from a Thecus NAS storage subsystem (shared as NFS3 in async mode for performance). The Finder does not appear to reliably copy data to/from the share. He constantly receives errors like this:

nfs server 193.168.130.211:/raid0/data/_NAS_NFS_Exports_/productions: not responding
nfs server 193.168.130.211:/raid0/data/_NAS_NFS_Exports_/productions: is alive
nfs server 193.168.130.211:/raid0/data/_NAS_NFS_Exports_/productions: not responding
nfs server 193.168.130.211:/raid0/data/_NAS_NFS_Exports_/productions: is alive

These errors are the end result of using either automounts via fstab or standard shell-level mount commands. We've exhausted all the obvious stuff like permissions on client and server. Google Fu suggests there are a few people out there who have had issues with MacOS and NFS but I am wary of taking that at face value. Instead, if anyone has general thoughts on reliability of MacOS and NFS, please share them with me?

Perhaps naively, I can't see why MacOS X wouldn't work with NFS and I'm rather thinking that we may have a hardware issue with the Mac, the switch / network gear or with the NAS box itself. To that end I tested on our main network with an older MacOS X 10.4 system using NFS Manager targeting a different NAS system and I was able to achieve stable performance. All very mysterious.

By JJ Franzen - I would turn off async as you usually only want to use that option on a tight LAN. If he's in over VPN, that can cause the timeouts you are seeing in my experience. I would also add the options timeo=600 and retrans=2. This should help with dropped packets... Also, iirc NFS v3 defaults to TCP for transport but it wouldn't hurt to be sure by adding proto=tcp into the mix as well. Good luck!

Pricing of cloud rendering service

$
0
0
By Brian Turner Ottosen - Hi all

We have a client in Brazil who is asking for advice on how to increase their render capacity for a 3D TV Series.

Project specs:
13 episodes of 25 minutes at 25 fps
3,185 shots
487,500 frames
1920x1080
Maya
Mental ray

I believe they already have a handful of render nodes on random computers but what is break even for when it is affordable to create your own farm? My feeling is that 8 months of work is far to little to really do this in house. Maybe if  they could keep 200 render nodes busy for the next 2 years we are talking. Any thoughts?

Does anyone have inputs on how to compare the true cost off cloud render services with in house rendering?

Here is what I have done so far:

First I have made some very rough estimates
The client reports that all layers and versions can rendered in 20 minutes per frame.
For 20 minutes of rendering per node per frame we need 162,500 rendering hours
In 240 production days this should be solvable by 28 render nodes disregarding the problems in keeping them busy at all times.

I am currently testing RenderRocket because they were among the top links on Google.
www.renderrocket.com

RenderRocket are pricing like this:
------------------------------------
Pre-paid credits give you up to a 30% discount by purchasing a block of time up-front. Our standard rate is USD $0.70 per processor (core) per hour. With pre-paid packages, you can get that rate down to USD $0.50 per core per hour.

Bonus feature: All our pre-paid packages give you the discount rate for 30 days after their purchase. This means that if you buy a $995 package and exceed the 1600 credits, any additional render time you use will be charged at the same discounted rate (10% off in this case).
------------------------------------

I assume our client ran his test on quad core machines so what they really need are 162,500 x 4 ~ 650,000 rendering hours

With the above listed pricing that would be $325,000. I expect a company selling in packages of $995 can make a much cheaper offer than just 10% of but still it gives us a ballpark figure.

On Zync www.zyncrender.com they would be able to get 12 x 60 cores in 28 days for $6,900. In 8 months that would be
~1,000,000 rendering hours for $55,200.

Does anyone have a rule of thumb for calculating the true cost of 28 inhouse render nodes in 8 months?

I have now tried to test render on RenderRocket and I can see that it introduces other problems when jobs are submitted via such a web interface. It would be to slow to submit 6000-8000 jobs. They would need a better integration. Do you know of any service with an API for scripting from the studio? Is there a render manager which can automatically handle submission of jobs to a cloud rendering service?

Still waiting for my 5 test frames from RenderRocket to finish.

I am looking forward to any feedback.

Brian.
:-)

StudioSysAdmins-Discuss Digest, Vol 47, Issue 33

By Terry Dale - The main question you have to ask is how much data are you sending and how much data are you getting back from the renderer. Then calculate how long that will take to transfer all that data if you are using a web based render service. Then cost our what it will take to expand your internet connection to handle that amount of data (if it even can) calculate the cost of bandwidth and the time costs to transfer all your data and you will probably find you can invest in a small onsite render cluster.

Windows submitting to linux render farm

By Tommy Nikjoo - Hi All, We're Mac/Linux shop with a Linux render farm, but have had a couple of Windows boxes creep onto the network which need to be able to submit Nuke renders to the farm. At the moment the linux/mac boxes all use the common mount of /mnt/sharepoint/.../... to the NAS to make the read and write file paths the same everywhere, but can't do this on windows. Does anyone know a way around this, or do I need to put a script in the middle to convert all windows file paths to /mnt/...?

By Drew Rosen - Hi List Users? Anyone super excited about a Final Cut Pro Timeline Troubleshooting experience? We have a project that has a mysterious issue where if you select an audio clip, it links to another audio clip that is not associated in any way to the original. Also, the fixing of this linking affects other timelines not active in the current timeline? Also names of the clips are randomly changed when fixes are made to the timelines? I've seen a few articles around the web, but nothing that gives a real solution or way to confirm our suspicions. The project was migrated from FCPX to FCP7, and we suspect that to be the source of the issue, and we are rebuilding the timelines, but it would be great to know if there is a XML under the hood or such that could be cleaned. Anyone seen corruption of this nature?

USB port control; related, Active Directory group policy on mac / linux

$

By Joe Chonacky -

Heya,

 

I’m working on doing some media access control in our shop – meaning limiting access to removable USB storage – as a security measure to protect client assets.

 

We’ve been researching products to help with this and have been having trouble finding anything that looks good and manageable, and ideally with some sort of logging of access granted.  The production floor is a mixture of PCs with WinXp (I know, I know), Windows 7, and Max OS 10.6.8 (played with Mt. Lion and it did some things I didn’t much like, such as being weird about binding to Active Directory… yep, pretty shocked he said in a very flat voice).

 

Two solutions that keep coming up: 1) Active Directory / group policy and 2) caulk.

 

My questions are:

 

1) What have others deployed to accomplish this sort of control, if anything, and did it do a good job,

2) Has anyone used Centrify Direct Control for Mac OS X (http://www.centrify.com/directcontrol/mac_os_x.asp) to extend Active Directory group policy to macs, and

3) What kind of caulk?

 

Thanks for any insight anyone might have,

 

--Joe

Adobe CCT strategies?

$
0
0
By Jean-Francois Panisset -
I'm trying to wrap my head around deployment of Adobe Creative Cloud for Teams (we're unfortunately not big enough to meet the minimum spend requirements for Creative Cloud for Enterprise). My initial idea was:

- deploy the un-registered software to all systems using AMEE and friends
- create "numbered" Adobe IDs corresponding to the number of seats / subscriptions we've signed up for
- create inbound email aliases for all these Adobe IDs
- "accept" the invitation to CC for Teams for these accounts
- when Adobe software is needed on a workstation, authorize it using one of the numbered Adobe IDs
- when it needs to be moved, de-authorize it and reuse the ID on a different machine.

Unfortunately, the CCT console doesn't show any information as to what host a particular Adobe ID has been authorized on, so although you can try to keep an external record of what account was used on what machine, the reality is that this will quickly get out of sync with reality. And although you can run the Creative Cloud GUI and it will show you the name of the account currently registered for that machine, I can't find a programatic way to get that info. I also can't find any kind of command line way of registering / de-registering the software, it seems that it can only be done by GUI.

So to try to keep some semblance of order, the other approach is:

- create inbound email aliases for each workstations where CCT might get run, named after those workstations
- when CCT needs to be authorized on a machine, create an Adobe ID named after that machine, accept the invitation, and use that Adobe ID to authorize CCT on that machine
- so now I should be able to see which machines have CCT on them just by looking at the list of Adobe IDs in the CCT console
- when CCT is no longer needed, de-register CCT and delete corresponding Adobe ID

Neither of those options are very attractive and will require lots of manual labor, but I don't really see a better alternative.

Has anyone come up with a better way to do this? Being able to extract the name of the Adobe ID currently registered on a machine (Windows + Mac) would already be a big win.

Hello everyone,

 

Just wondering if anyone out there has contacted Isilon support lately?  We are having some major issues with EMC support and things just aren’t getting done.  I’ve been with them on the phone many times and things keep getting escalated with no real resolution.  It would be great to hear what other people are experiencing lately.

 

Thank you and looking forward to all your replies
