Q: deleting reference master files

Os Lion 10.7.1

OK we'll need to recreate the .Trashes file on the external volume.

In the terminal type

• sudo rm -rf  /Volumes/DriveName/.Trashes

Make absolutely sure there is no space after the drive name and the /.Trashes or  anywhere else in the file designation. If this line is incorrect you will wipe the disk.

Now unmount the disk then remount it. The .Trashes directory will be recreated with the correct permissions.

Do an

• ls -la /Volumes/DriveName/

Note the permissions on the .Trashes directory. You should be able to delete the masters again.

Again the rm -rf run as root is a dangerous thing. If you follow these instructions you'll be OK. But make sure you're comfortable with them before going on.

We have done the rules in the Terminal and it looks like this now on our External Drive:

d-wx-wx-wt    2 levindenboer  staff     68 19 aug 09:25 .Trashes

And serious, we still can't delete the Master Images files!!!!!! AAAAAAAHHHHH!!!GRMLFFFF

• You don’t have access to the System Trash on the master files’ volume.

Again!!! On our iMac the line looks like:

iMac = drwx------    2 levindenboer  staff     68 19 aug 09:17 .Trash

External disk = d-wx-wx-wt    2 levindenboer  staff     68 19 aug 09:25 .Trashes

Sorry to hear that the last steps did not resolve your problem. In all instances in the past where I've seen this situation this has fixed it. The permissions on the .Trashes file on the external drive are now correct.

Just to be clear you deleted the .Trashes folder using the rm -rf command, unmourned and then mounted the drive and the .Trashes file was created with the permissions you are showing?

I don't beleive the .Trash file on the root drive is causing you problems. Do you have root login turned on by any chance?

Just to  to be sure; the masters are on the external drive and your home folder is on the root drive.  Any other information you can supply might help figure this out. Any customization of logins or permissions, etc?

One test you can try, copy or create a file on the external drive then attempt to delete it with the Finder (not in the terminal). What happens? You can also try doing (in tthe terminal) sudo ls -la /Volumes/DriveName/.Trashes . I'm looking to see what if anything is in the .Trashes Folder.

One last thing you could try posting to the Lion list here explaining what is happening and what you have already doen. Perhaps there is some quirk in Lion that I am unaware of.

good luck

Hello Frank,

Yes, we deleted the .Trashes folder using the rm -rf command, and unmounted and mounted the disk back on.

This will show the rule : d-wx-wx-wt    2 levindenboer  staff     68 20 aug 12:13 .Trashes

Yes, the Master images are on the External Drive and the Aperture Library's are on our iMac.

The Vaults of those Library's are on a second external drive, but only the Backup Vaults from Aperture.

Yes, we can delte files, folders on our External Drive where the masters from Aperture are. But when we whan't to delete files directly from Aperture we get the error message.

So, i think it's a Lion thing indeed. But where can i put this problem than?

This big problem apears indeed after we updated to Os X Lion from Apple.

Can it be the RAID system of the External Drive. We use the new Pegasus R6 from Promise Technology . There are several settings in the control system. But we don't touch that because it works fine now.

Does anyone have a solution with this problem! We still have the problem. The thing is now, when we have done al those ls -la /Volumes/DriveName/ codes the old maps are available to delete.

But when we make a new map true the applicatian Aperture , we get the same message again!

So it looks like that Aperture is making the folders on our external disk with a permission that it not be able to download the master images from that disk??

It's so frustrated that we can't delete the master images...

Sorry to hear you still have this problem.   It appears that you've got some really new hardware there, according to the website it appears you're connecting via thunderbolt, is that correct?

I would get in touch with the hardware vendor. They might have a solution and if not they might be interested in troubleshooting this as it is so new.

I would also suggest yu try the Lion list here. There may be something specific to Lion that I am unaware of.

It does seem strange that you can delete files on the external drive via Finder but that Aperture can't do it.

goo luck

We use indeed the new iMac i7 with thunderbolt.

And we can delete indeed the images directly from the external disk in the finder.

And when we try it within Aperture it wont work?? Strange indeed.

I just did a new ls -la /Volumes/diskname and i see this line now;

d-wx-wx-wt@   3 levindenboer  staff    102  3 sep 15:00 .Trashes

What's the @ sign behind the line d-wx-wx-wt? It seems that when we turn the external Pegasus R6 off and on it build its own permissions?

And on our new iMac the line look like this:

drwx------    2 levindenboer  staff     68  3 sep 14:30 .Trash

Is that maby the problem?

The @ sign at the end of the ls listing indicates the file has extended attributes set on it. To see the extened attributes add a @ to the ls comand ie:

ls -la@

Don't know why or who is setting them, post the new ls output and it may indicate something.

As for the ls output on your new iMac I'm asuming that the line you showed is comming from the iMac's root

volume, is that correct? The trash setup on the root drive is different then the trash setup on other volumes and I don't beleive this has anything to do with the problem you are having.

On the root volume each user has a .Trashes folder in their home directory. When you delete a file on the root volume it goes there. On all other volumes each volume has a .Trash file at the root of the volume. When a user deletes a file on that volume  a folder named with that users UID is created in the .Trash folder and the deleted files are placed in that. 

One interesting experiment to do: You said you could delete a file from the external drive with the finder. So do this but don't empty your trash. Do an ls -la on the comtents of the .Trash folder on the external volume you should see a folder in there named with your UID. Now try deleting from within Aperture. Any change?

One last thing you're not doing anything strange with users right? You're accounts are just normal users acounts created by the OS X? The master files and the library are all owned by you? You haven't tried to setup any sharing of the Aperture library or raw files correct?

regards

First here is our workflow:

And i'm not an expert in Terminal command's, so could you be specific what i have to do?

I'll deed the folowing steps, i put 1 image from an folder to our Trash can on the iMac directly from the external disk.

If i do the following line you will see this:

ls -la /Volumes/Pegagus R6/.Trashes

total 0

d-wx-wx-wt@  3 levindenboer  staff  102  3 sep 18:14 .

drwxrwxr-x+ 21 levindenboer  staff  782 20 aug 12:20 ..

drwx------@  4 levindenboer  staff  136  3 sep 18:14 501

i Don't now what to look at?? But i see something like Total 0

Could this will be the problem?

If i check our trash can on the iMac it shows 1 picture indeed. But when i'm going to Aperture and choose Delete Masters it won't work?

Wow this is weird???? I did a another test, i deleted something from my imac in the Trash and did the same command, an then it shows what's inside the Trash.

ls -la .Trash (now with 1 pictures from the external disk directly true the finder in the Trashcan)

total 0

drwx------   2 levindenboer  staff   68  3 sep 16:11 .

drwxr-xr-x+ 18 levindenboer  staff  612 25 aug 14:14 ..

ls -la .Trash (And now with 1 picture from the iMac and the picture from the external, but it shows only the one from the iMac)

total 48

drwx------   4 levindenboer  staff    136  3 sep 18:25 .

drwxr-xr-x+ 18 levindenboer  staff    612 25 aug 14:14 ..
