Hi Andrew,
To run a file system check on sda3 boot from a rescue disk an run:
fsck -n /dev/sda3
This will tell you the problems with the filesystem on the partition
If the data on sda3 is critical to you, or there is major corruption,
then you should backup the raw partition before trying to repair.
To repair the partition run:
fsck /dev/sda3
And answer "y" when asked to fix each problem.
Regards
Kim

Hi Manoj,
Thank you for your response. I have had a look at those links, and
they are quite a bit "over my head", so I wonder if I should use the
rescue disk to facilitate shifting my ~/working directory to my RAID
disks. (Nothing else is of any consequence) and then use a Ubuntu
18.10 DVD to upgrade the distribution and hopefully create a new GRUB
on (in old terms) /dev/sda3
Thoughts?
Thanks

Hi Andrew,
From the logs it looks like your sda3 partition (btrfs) is corrupt.
Perhaps you could boot from a rescue CD/flash drive and try some of
the suggestions on these pages?

Hi All,
I have discovered a Ubuntu Boot-Repair -Disc which avoids syntax
issues,
I was unable to come up with a satisfactory syntax for the commands
needed to solve this problem. Suitably chastened I have located a
laptop
which has Thunderbird so now I can keep the thread on the list. My
attempts to communicate from a tablet produced a pile of crap.
I downloaded and burned a Disk-Repair-Disk for Ubuntu
I have run the recommended steps to repair GRUB 2.8, but nothing has
been achieved.
I did request the log be sent to a paste bin just in case, and as
it is
a few pages of text here is the link.
http://paste.ubuntu.com/p/pNsZCYF5QZ/
The last line acknowledges the failure to achieve a result.
This machine is critical to my work, and I had considerable
assistance
earlier in 2019 to achieve a RAID system on this machine, for
which I am
truly grateful.
I would appreciate any assistance with this problem.
