Also, changing crypttab:
root@glet:~# cat /etc/crypttab
sda6_crypt UUID=fe03e2e6-b8b1-4672-8a3e-b536ac4e1539 none luks,discard
removing discard didn't solve the issue.
In my setup it was enough to boot the system, so having complain about
/home mounting
impossible (no filesystem found).
Well, keep in mind that at boot I have a few things, like:
root@glet:~# grep -i swap /etc/fstab
/dev/mapper/cry-swap none swap sw,discard=once,pri=0
0 0
/dev/nvme0n1p2 none swap sw,discard=once,pri=1
And other stuff in cron and so on.
So I can trigger the problem at boot (ubuntu 19.04), by my changes.
Hope it helps.
