Upgraded to 7.30 I seem to have lost an array. My system is configured as such Mirror 1 Set as cache and appdata - 1 512GB NVME SSD - 1 512GB SATA SSD Mirror 2 2x 2TB 7200 RPM SATA drives connected to USB JBOD After the upgrade the second mirror named main (BTRFS MIRROR) has disappaeared. The disks show in the gui as unassigned. I manually mounted the drives to /test and they appeared to mount and my data is there. The disks show no errors and have been working just fine for months. I did see a CRC error returned to normal in the console after the upgrade refering to one of the drives. I shutdown everything including the jbod gave it a good 30 seconds and powered up the jbod then the computer. Still not showing in the console. I would normally think I need to do a scan or something to make unraid see the array and import it but don't want to lose the data.
