Okay, I am nervous about losing 10+ years of personal data. Your help would be greatly appreciated! I now have all four drives copied (with ddrescue) from the originals. The new copies are connected to the system; the original drives are not. When attempting to boot from my normal boot drive, I see this very early on in the boot process: Booting... errror: found two disks with the index 0 for RAID md/teramooch. error: found two disks with the index 3 for RAID md/teramooch. Later, once the dmesg material appears, I get to: ** WARNING: There appears to be one or more degraded RAID devices ** The system may have suffered a hardware fault, such as a disk drive failure. The root device may depend on the RAID devices being online. One or more of the following RAID devices are degraded: Personalities : [linear] [multipath] [raid0] [raid1] [raid6] [raid5] [raid4] [raid10] md0 : inactive sdi1[3](S) sdg1[0](S) 3907021954 blocks super 1.2 unused devices: <none> You may attempt to start the system anyway, or stop now and attempt manual recovery operations. To do this automatically in the future, add "bootdegraded=true" to the kernel boot options. If you choose to start the degraded RAID, the system may boot normally, but performance may be degraded, and a further hardware fault could result in permanent data loss. If you abort now, you will be provided with a recovery shell. Do you wish to start the degraded RAID [y/N]: Timed out Gave up waiting for root device. Common problems: - Boot args (cat /proc/cmdline) - Check rootdelay= (did the system wait long enough?) - Check root= (did the system wait for the right device?) - Missing modules (cat /proc/modules: ls /dev) ALERT! /dev/mapper/teramooch-root does not exist. Dropping to a shell! BusyBox v1.18.5 (Ubuntu 1:1.18.5-1ubuntu4.1) built-in shell (ash) Enter 'help' for a list of built-in commands. (initramfs) _ I then rebooted and allowed the system rescue cd to boot. cat /proc/mdstat gives Personalities : [linear] [multipath] [raid0] [raid1] [raid6] [raid5] [raid4] [raid10] md127 : inactive sda1[3](S) sdc1[0](S) 3907021954 blocks super 1.2 unused devices: <none> What should I do from here?
