Re: Grub 2 Issues - was Weird Boot
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?

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.

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 On 15/1/20 11:54 am, Andrew Greig via luv-main wrote:

Hi Andrew, * It is a good idea to backup whatever you can, before you do anything else. * Once you have that out of the way, try $btrfs scrub start /dev/sda3 * I personally haven't used btrfs much, but I believe it may be better to try a $btrfs check --repair /dev/sda3 before you do the fsck as Kim suggested. -Manoj.C -Manoj.C On Wed, Jan 15, 2020 at 12:16 PM Kim Oldfield via luv-main < luv-main@luv.asn.au> wrote:
