Problem with file system/fstab

I have a RasPi here with the RasPi build you provide. I'm booting the rootfs from an external hard drive which is located at /dev/sda1 and also has the same UUID as /dev/mmcblk0p2 as this was a dd clone.

/dev/mmcblk0p2 still appears in the file systems page even though it is not mounted and I believe I have removed it from my .config.xml file (I made a backup). Not a huge problem though.

The main issue is with another partition (/dev/sda3) on the same hard drive as the system boots from - it has my SQL databases on I use for shared folders/OwnCloud

I've changed hard drives and cloned information from them to another (/dev/sdb2) but this has messed up my mounts and the file systems page:

My fstab is as follows:

When I 'mount -a' now for some reason it decides to mount /dev/sda1 to the same location as /dev/sdb2 is supposed to be mounted. In the web interface it shares the same available/used values because of this.

When I try to unmount certain partitions now I get a message similar to:

Zitat

Failed to get configuration (xpath=//system/fstab/mntent[dir='/media/5d18be51-3217-4679-9c72-a54e0fc53d6b'])

However if I mount/unmount the drives manually it seems to solve it.

Ideally I'd like to mount my drives in a custom location like /media/USB1 (within the OMV interface) and still be able to use them for shared folders and with OVM interface. It'd be great too if I could use the 'mount/unmount' buttons on the web client.

Not sure if this is possible but I'm in a bit of a jam...

I mean is it possible to reset the file systems as it were?

Yes, I had to delete entries in config.xml, create new UUIDS with 'tune2fs -U random /dev/sdXY' then reference them in my fstab:

Looks likes everything is working now

Is there a way to trick OVM to thinking that a referenced drive is not referenced with bind mounts?

Currently I can't create shared folders on 'media/Crypt' which is not referenced - what does a file system need to be able to use it in shared folders?

Mounting via UUID seemed to fix the issue.

Obviously, by I am using the RasPi build and 'dd'ed the SD card to a USB drive. It says it cannot mount rootfs if I don't fstab it.
