Well, forget Part 7 (fortunately). The SSD-Raid is working fine! It always assembled itself after several reboots. That’s good news, I guess!<\/p>\n
In the meanwhile I fucked up again. I ordered an external USB-casing without a disk recently. While trying to get it up and running, I accidentally disconnected the USB-thingy connected to my external drives from power. Since then the kernel complains about the 2.5″ USB drive without power supply, but I got it up and running again.<\/p>\n
Right now I’m copying all data from that drive to a member of the failed HGST-Array. Hopefully it’s not<\/strong> the failed drive, but we’ll see…<\/p>\n Creating a physical volume with pvcreate didn’t work out of the box. The command bailed out saying that it couldn’t open the device exclusively. At first I thought that it was because of the pre-existing PV-Signature, so I zeroed out the first GB, but that didn’t help, either.\u00a0 Check-MK came to help, telling me that md127 was in a degraded state.<\/p>\n Of course! The drive contained a RAID-Superblock, so the kernel tried to start the the RAID, but couldn’t. Nevertheless, that kept the drive busy.
