LL 5.4 - New Install - Error : Diskfilter writes not supported - CP_ PDN - 04-03-2021
Hi guys, just installed LL 5.4.
The above msg -> Error : Diskfilter writes not supported
pops up a for few seconds and then the bootup continues.
I am about to install LL 5.4 onto another machine.
What can i do to avoid this error ? Googling shows its something to do with LVM
( i did choose my disk to be formatted as LVM ). Reading posts here - i can see that this error has appeared in earlier versions as well ?
Pls advise.

[ GRUB uses the diskfilter module (insmod diskfilter) in RAID partitions, and the lvm module in LVM partitions ]

Follow Up ( Based on https://askubuntu.com/questions/468466/diskfilter-writes-are-not-supported-what-triggers-this-error )
For a temporary fix for this problem :
Edit :/etc/grub.d/10_linux
Replace 'quick_boot="1"' with 'quick_boot="0"'
Then :
sudo update-grub
But just wondering, if the LVM / RAID part is buggy, why would the installer provide this option if this is a long standing bug ?
Or nothing can be done as this is the standard installer from Ubuntu and LL is waiting for an upstream fix?
