At the moment everything is working. But I'm pretty sure things will eventually turn upside down again. My best guess is that one of my drives is defective, but the failure is intermittent. I need something to check the disks, sort of like the memtest tool that appears in the grub menu. I want something that will check every part of each drive, repeatedly. I haven't completely given up on LVM, and I may end up there eventually. But while poking around I stumbled on F2FS, a Linux filesystem for flash drives written by Samsung.
