How do logical volumes inherit/ propogate security?

We had a user who set all their permissions correctly to view files in a folder but couldn't view the files. After a lot of troubleshooting we found out that the physical volume did not inherit security from its parent logical volume, so the user was denied access.

At what point does inheritance happen?

Now that the user has rights on the parent logical volume, will any future rollover volumes inherit the security placed on that?

If I encountered a logical volume that had 100 physical volumes and I wanted to change security on it/ all of them, would I have to update the security on each physical volume separately?

Since the physical volumes can have different security from the logical volume, the security inheritance only happens at the time the physical volume is created.  Any changes to the logical will only be automatically applied to the next physical volume and any existing volumes will not change.  To apply the rights to the physical volumes, you will have to manually set them on each existing physical volume in the Logical volume.

Thanks Bert, that's exactly what I was looking for.

Well in this case, how do you fix the security across all sub volumes at once?

I do not know of any way to mass apply/change security on multiple physical volumes.  The only way I know of is to either step through and change each volume independently or do it with SDK custom app/script.

Got it, we just updated the latest one for now and will move them to cloud where it will no longer be an issue next week. Someone had put a deny on the master repository and it slowly applied to every single rollover volume over time, like an unfathomable amount of 4GB rollover volumes.

I have had a lot of trouble managing rollover volumes and prefer fixed by far, which still creates subfolders every so often.
