btrfs root partition is in /dev/sdb (a small SSD). It also has another EFI partition (from the original W8 OEM) but that is not relevant to the issue.
When I boot from partition magic liveCD (June 2017 version), that doesn’t mount any partition on the existing drives. I can check other partitions with gparted right click menu option (I guess it uses fsck), but sda6 errors out with message “can’t unmount, drive is busy”.
Hi
I would suggest booting from a live TW desktop or TW rescue system and checking things out… you would need to look at the output from the mount command or top to see what it’s doing on the Partiton Magic setup, isn’t that a pay for use thing now, maybe it can’t handle xfs…
Yes, it’s a pay (cheap) live distro. I’ve bought it two or three times this decade, when I couldn’t easily fix some issue with other tools. It does aggregate a lot of tools, has many different boot options, an agreeable and informative desktop, etc. It’s worth the occasional expense, although it is not a fix-all solution - like now, perhaps.
I’m downloading TW rescue LiveCD now, will report how it goes.
I’m still puzzled about what could cause a partition to be reported mounted. There are two other XFS partitions on sda (/tmp e /var/log), but I didn’t test them at the time. I remember creating XFS partitions with it, but I’ll check them anyway. The only other thing I can think of is a hardware (HDD/RAM) issue.
Question: oS DVDs used to have memtest, but LEAP doesn’t. TW rescue has it, or if not where do I find it?
From thumbleweed rescue, gparted works all right, and the xfs partitions check OK.
The grand advantage of PM is that it can be loaded entirely in memory if you have 1GB+ RAM. This makes things much faster that the liveCDs - subjectively I’d say 10x faster, at least comparing to an USB2 external CD drive.
Anyway, my boot problem is not due to this, so I’ll open another thread if I can’t fix it.
