I have two external usb drives on a RPI running OMV. On a recent startup, only 1 of two drives (sdb) showed up after OMV started. I found the cause of the problem and restarted omv. I can see both drives under the storage, disks option. The array hasnt started a rebuild as I would have expected.
When I look at the array status in ovm gui, it only shows sdb1, not sda1. Given the situation, wasnt sure how to readd the drive to the raid 1 array.
Would appreciate any suggestions.
