Stephen Marshall writes on the Arrays forum -

Hi everyone,

I need some help with a very strange issue.

I use SANmp to connect to two raid arrays, RAID A and RAID B. Yesterday when I mounted RAID A, none of the file paths were correct - Final Cut was acting as though it wasn't there etc etc.

Now in Finder it still says the array is called RAID A, the normal file path would be

/Volumes/RAID A/xxxxx/xxxx

However they are now:

/Volumes/RAID A 1/xxxxx/xxx

Why has a "1" suddenly been added to the name? I repeat, it doesn't look like this in the Finder window, or the "Get Info" window.

Any help or suggestions you guys have would be great.

It's probably the case that it was unmounted properly at one time and an older directory exists in there with the old name. Apple will automagically rename the mount point by sticking a "1" on the end of it in that case. (I've been caught by this before).

Unmount everything and check in /Volumes for the old mount point. Maybe do a check permissions too in case anything was left in a bad state.

Looks like we think alike, Steve - and at the same time!

Any luck with your uber-low bitrate encoding project?

I got video going with mp4, but the delay on the stream is quite high (we think due to the encoding). I'm wondering if there are cameras that will encode for us that we can stream out with vlc directly (native MPEG TS container stream straight to ethernet)

I think Steve's got the right idea. This is probably an example of Mac OS getting a little confused.

First, confirm that you really don't have two volumes with the same name! You probably don't, but it's worth asking.

If a reboot does not resolve the issue, please see the steps below:

1. Make sure that all SAN volumes are unmounted.
2. Repair Permissions.
3. From the Finder pull down the Go menu and choose Go To Folder (or use shift-apple-G shortcut). Type /Volumes/ and click the Go button to open the /Volumes folder.
4. The volumes folder contains an alias for all the volumes mounted. I suspect that you'll see is an old alias for your volume that for some reason did not get removed when it should have been. Since this alias already exists, OS X appends the "-1" to the volume name the next time a volume with the same name is mounted.
5. Since you have no SAN volumes mounted (re: step 1), you can safely trash the incorrect alias from the /Volumes folder.
6. Reboot, check the /Volumes folder to make sure the old alias is indeed gone, then mount your volume in SANmp Client to test that your links are correct in Final Cut.

If this fails to resolve the issue, you can open a support case with SNS by sending an email to support@studionetworksolutions.com

While I don't have an exact reason why...here is some speculation.

Lets say during a power down, the Mac doesn't "release" (unmount) the volume. When then the system boots back up, and the OS sees the same volume, but reports the other volume is still mounted - because it didn't unmount properly. The Mac may append the name to 1. Much like if you attempt to download the same file to the same place, the OS appends the file name with a "1".

Vague, but perhaps an option to explore?
