So one of my drives started clicking and a visit to the command line for OMV 4 showed DRDY SENSE ERROR, failed command: READ DMA EXT, Print_req_error: I/O error dev sdd sector 7814036992, Buffer I/O error on dev sdd, logical block 976754624, async page read, etc. A visit to the OMV GUI indicated that Drive sdd has been removed and the File System is now missing.
I know I have to replace the drive sdd. So after I shut down the system and replace Drive sdd, how do I recover the Array? In the past when a disk failed, my file system continued in a degraded mode. In this case, the array is not mounted and the file system is missing.
I consider myself a Linux and OMV novice, but I can follow instructions and realize at this point I need help.
I have attached a photo of the command line traffic and a couple of print-to-pdf screen captures of the OMV GUI.
