Photoshop: CS6 can not overwrite files on XSAN storage (files lost)

  • Problem

Hi,
I am using latest Photoshop CS6 on OSX. I use XSAN 3 storage on OSX server (latest, updated)

I can not overwrite existing files.

Error is: I get "Could not save "filename.psd" because of a disk error.

During this failed write original file is lost.

File permissions are OK. Disks are all good. All other applications (including Adobe's) can write/overwrite files on XSAN storage (in the same folder). This is not a permission problem.

It happened before on CS2 (other users report on apple's website)

Any help appreciated.
B.

The disk error part means that the OS returned an error.

Which OS version are you running on your client machine (not the server)?

And have you asked Apple to investigate the problem? (so far these server errors keep boiling down to bugs in Apple's file code or third party server code)

Hi,
Using mountain lion on client and server (latest at the moment)

I opened discusion on apple's website https://discussions.apple.com/message...

Save for the web works (new files and overwrites). That would suggest that there is something with Photoshop save that is not entirely ok.

Workaround is to save files over network share instead of fibre channel (but that is not realy all that great)

I red on apple's forum that there ware simmilar issues with Photoshop CS2.

All other adobe apps appear to work fine (ae, illustrator,...)

Thanks,
B

Again: every time we investigate these issues we find the root cause is in the OS file code, or third party server code.

MacOS 10.8 does have serious bugs in the resource fork handling, which has been causing program errors when saving to SMB volumes, and sometimes AFP volumes. Apple has acknowledged the bugs and is working on a fix.

You might be seeing a variant of that bug, and could try turning off all thumbnails in Photoshop's file preferences to minimize the impact. But because you're getting a disk error, that means that the OS has returned an actual disk error to Photoshop - which means it may be a different underlying problem with the file system code or interface drivers to the XSAN.

Why does this show up in Photoshop? Probably for the same reason that many other problems show up in Photoshop first - Photoshop does a lot more error checking when reading and writing files because we've seen many different OS bugs and go out of our way to try and keep your data is safe.

Thanks for the "ping-pong" answer.
(I'll probably get the same from apple)

Hi,
Chris can you please check our discussion on Apple
https://discussions.apple.com/message...

It appears that there is a problem with Photoshop CS6 (one user is running on Xsan 2.3 and Snow Leopard)... I was once running Snow Leopard with earlier version of Photoshop without any problems.

I guess this not qualifies as a bug report.

Thanks,
B

Everything you've posted makes it sounds like it's an XSAN bug.

Apple is working on fixes for a couple of network saving issues in 10.8.x, but we don't have any ETA yet.

To someone at Adobe:

Hi,

This thing is dragging too long... I can not use Photoshop to save files.

I know that you can always say: it's Apple's problem... guess what Apple say's!

This needs to be sorted out, so please call someone at Apple and sort this out!

Regards,
B.

10.8.2 fixed the major filesystem issues in the OS that were affecting file saving in Photoshop (and many other apps). Apple does not seem interested in porting their fixes to older OS versions. And we're still waiting on other OS filesystem fixes.

So far we have not found this to involve bugs in our code, just bugs in MacOS filesystem code.

We're waiting for Apple to fix it, just like you are.
If you'd let Apple know that this is important, it might move it up their list of priorities.

OK, it's one of the unfixed filesystem bugs. You'll need to tell Apple that this is a priority and that it needs to be fixed soon. (we've already asked Apple to fix these bugs, but hearing from customers can improve their priorities)

Hi, I am doing that since mid the end of august...

Can you please comment on this post:

I would love for this to get fixed, and not just have Adobe and Apple pointing at each other while the paying customer's are the ones who have to deal with the fallout. Why don't the two companies do some collaboration to get this fixed.

Apple has identified the cause of some of their other fileserver bugs recently. But we don't have an ETA for fixes on all the known OS fileserver issues.

We keep working with Apple, and they eventually find the source of their OS bugs. Meanwhile we keep trying to find workarounds to their OS bugs.

And the ETA is now: 10.8.4 fixes the known XSAN bugs in the OS.

10.8.3 was released the other day. I am curious if anyone has done any testing to see if there has been any improvement to this problem.

I plan on doing so myself in a test environment at first opportunity and will report back with what I find.

I have been struggling with this issue for months now.

Adobe please help!

My supervisor has the opinion that it is because Photoshop's saving process hasn't been updated for years and is behind other Adobe products, but who knows?

I have the latest iOS updates, Mountain Lion and Photoshop CS6.

I get the same problem as the main post + occasional "ghost files".

These "ghost" PSD files can sometimes be recognized by After Effects, but are not visible in iOS finder.

The only work around is to save your PSD to the desktop, and then drag it to the XSAN. This is not easy when you are doing tons of edits. Please help!

We're working around the OS bugs as fast as we can.

This one appears to be a combination of bugs with MacOS and XSan software, and we're not sure we can work around it.

If you would like to see the real problems fixed, please let Apple know that you consider this a priority and that they should fix their filesystem bugs as soon as possible.

Also, your supervisor really has no idea what they're talking about.

I am not defending Apple but other apps are saving files just fine.

In most cases we investigate, other apps are silently losing documents while Photoshop catches the errors from the OS -- Photoshop has added extensive error checking on file IO because we've had to debug so many of these OS bugs.

problem is that this affects few hundred users and it's not worth spending time on

I resolved this by unchecking "Native Extended Attributes" when setting up a new Xsan. The issue is reproduced every time with it checked, does not occur with it unchecked. The downside is it requires you to re-initialize your Xsan to make this change on an existing deployment.

Thanks Tony for the resolution! I bet that took a bit to figure out.

Like you said, the downside is that I doubt our admin will want to move/re-initialize 30TB just to tweak a Photoshop issue.

We're not talking about a Photoshop issue, but an OS or fileserver bug.

Resolves an issue saving files to an Xsan volume from certain applications

I have verified on a test XSan using the metadata server with Adobe installed that 10.8.4 does appear to resolve these Photoshop overwriting issues on CS6 running 10.8.4 without having to re-initialize the San to disable Native Extended Attributes.

Keep in mind that this test was done using a metadata server as the test machine running CS6.

Apple says that the known XSAN issues are fixed in 10.8.4.
And in our testing they appear to be fixed.
