As others have already pointed out, this was not a one-drive failure. In my case, the two SATA disks which are still functional are connected to a 3ware controller while the four failed disks use the onboard SATA controller [1]. Therefore I'm confident that this is just a problem with the onboard SATA chip and that the array can be assembled again after a reboot. I'll have to wait until the end of the week to reboot that machine though. Are you also using an Intel-based SATA chip (please send the output of lspci -v)? Also, which kernel version are you using? > 5) Any insight as to how this happened / can be prevented in future ? Don't use cheap hardware (Fast, cheap, good.
