That’s awesome news @Alex_Altair.
Your experience with Ubuntu Live (especially /usr/bin/fsck: Input/output error
) hints at the wake-from-sleep problem that afflicts some WD SSDs. This might also account for the original LVM2 and filesystem metadata corruption that caused your boot failures.
I encourage you to have a look at the (long) thread I’ve quoted below.
The contribution I quoted above is my attempt at cutting to the chase. The thread documents a journey. It might be worth reading. Firmware updates are not without risk and I’d like you to be fully informed.
Firmware aside, you can bolster your leap of faith that fsck
did no damage. Run this command line.
$ sudo find /lost+found/ | wc -l
1
The expected result is as shown. Post back here if output is anything other than 1.
