Hi there,

 

I restarted my sever and got the error "Unmountable: Unsupported partition layout" on all my disks. They are 3x2TB HDDs xfs-encrypted. I tried to repair the drives with xfs_repair, however it didn't change a thing. GDisk gives me a "Read error 5" with only the MBR available. SMART Diags tell me nothing is wrong. Did the reboot somehow brick my array, so that I have to format the drives or is it possible to save my data?

You are having a hardware problem:

Are the devices in some kind of enclosure?

Hey, thanks for your reply.

The drives are sitting in cages connected to a sataboard, which is connected to unraid via USB.

Try disconnecting and reconnecting and/or using a different USB controller, but note that we don't recommend USB for array devices.

Your hint was the key to it. I was very confused, because I could "access" my drives, did'nt think about restarting the cages as well. I'll check if everything runs now and update this post soon. Thank you!

Everything seems to be up and running. I'll look into a different option for attaching my drives.
