A partition that is totally off-limits unless I say otherwise is being mounted without my knowlege, permission, or directive AND I can't even unmount it?
Of course you cannot unmount your root partition.
That was a goof or maybe I was booted into partition 9-11, trying many different things these days. BUT your hint led me to question why KDiskFree was showing dm-9 as / when it was supposed to be partition 8. So I booted manually and got dm-8 which is what it should be. On the next boot I went again with the grub menu but ended up with dm-8 and not dm-9 as after the previous grub menu boot. I'll try to investigate a little more from a rescue frisby...
Just went over the lot from a Live-TW and everything that I can see checks out, partitions 4-11 are bootable and boot no problem manually, all the fstabs jive with the 3 blkids in each (/, swap, data), nothing to do. However this TW in partition 8 is throwing different fits, and I don't think its grub. VERY SLOW to BOOTZ. Before taking off on this investigation /dev/dm-9 was showing in KDiskFree as / instead of /dev/sda8. Now /dev/dm-14 is showing where /dev/sdb1 should be for data (/0/adat). Both of these readings are definetely wrong. There are /dev/dm-12, /dev/dm-13 & /dev/dm-14 but digging into them is above my paygrade. There is no sign of any /dev/dm 12,13 or 14 in fdisk: https://transfiles.ru/7hvv1 I'll be booting manually for a while.
