On boot up - Generating new host keys - Shares gone

[BigBirdie]

I have added a new Parity Drive as the old one failed and shut down.

It built the new Parity OK

As I was short of space, I swapped out a 2T drive with an 8T drive. Data was restoring, but system crashed some time during rebuilding drive 2.

I swapped the data cable on the Parity drive.

On starting up, I noticed the boot sequence looked different.

One message said it, "Couldnt find device "bond0"" another was that it OpenSSH SSH daemon.... generating new host keys: RSA

 

System started as Tower, and root signed in, and IP address was wrong.

Reboot and started up OK, but my shares are gone. Parity drive is rebuilding.

 

What should I do?

Is there a way to restore an old USB boot config, with the shares data?

I seem to remember there is a copy saved on the USB??

The system hung again, while the parity was running. it got to about 25%

The GUI was different, I have the dark theme. It went to the standard white and nothing showed up.

I went terminal and reboot.

Now I have all the shares available, and the parity is starting to run again.

Attached it the Diagnostic file. Appreciate any help stabilizing my system.

That might not be the only problem but you need to check filesystem on disk1:

I have the old Parity drive and Disk 1.

I tried putting them back in as they were but it says they are wrong.

I suspect that the Parity drive crashed when it was rebuilding disk 1.

Is there a way to put them back as they were and start again?

You can do a new config (Tools -> New config), parity will need to be re-synced.

I have fixed the issue, here is what I did.

I continued with the 8T parity drive, and completed the parity check.

I added the the old disk 1 as an Unassigned device.

Add the new 8T disk1.

This disk had an issue for I formatted it twice. and it mounted OK.

I used Krusader to copy the data and folders off the old disk to the new one.

All has been running for while. I hope it stays stable now.

This has taught me to buy a NAS server and back this all up NOW.

2 drive failure is the worst.

@JorgeB Thanks for the help!! Much appreciated.
