Mount previously created encrypted disks

[lko]

Hi,

 

I'm thinking of migrating from OMV 6 to Unraid 6.12.8.

 

I have four disks, which are first encrypted with LUKS and then formatted as XFS.

 

However, when I add the disks to Unraid array and select "xfs - encrypted" as file system type, enter my LUKS password and start the array, I get "Unmountable: Unsupported partition layout".

 

Here are logs from this operation:

Mar 14 03:22:28 Tower emhttpd: Opening encrypted volumes...
Mar 14 03:22:28 Tower emhttpd: shcmd (215): touch /boot/config/forcesync
Mar 14 03:22:28 Tower emhttpd: Mounting disks...

Mar 14 03:22:28 Tower emhttpd: shcmd (221): rmdir /mnt/disk3
Mar 14 03:22:28 Tower emhttpd: mounting /mnt/disk4
Mar 14 03:22:28 Tower emhttpd: shcmd (222): mkdir -p /mnt/disk4
Mar 14 03:22:28 Tower emhttpd: /mnt/disk4 mount error: Unsupported partition layout
Mar 14 03:22:28 Tower emhttpd: shcmd (223): rmdir /mnt/disk4

 

If I open a shell, I can easily decrypt and mount the disks with:

root@Tower:~# cryptsetup open /dev/sdc sdc_decrypted
Enter passphrase for /dev/sdc: 

root@Tower:~# mount /dev/mapper/sdc_decrypted /mnt/sdc_decrypted

root@Tower:~# mount
....
/dev/mapper/sdc_decrypted on /mnt/sdc_decrypted type xfs (rw,relatime,attr2,inode64,logbufs=8,logbsize=32k,noquota)

 

What am I missing here?

 

Cheers!

Unraid requires a specific partition layout, you can mount the disks with UD, but to mount them in the array you will need to re-format them first.

Ouch, okay. Thank you Jorge for the explanation!
