diskfilter writes are not supported - Makrand - 07-12-2020

Brand New installation of Linux lite latest 5.0. while booting getting message on screen as shown in title. Asking to press (K) to continue. If not pressed....boot ok.

Looks like this is some bug that is travelling in each LL version??

Hi!

Read this article:

https://askubuntu.com/questions/468466/diskfilter-writes-are-not-supported-what-triggers-this-error

You probably installed Linux Lite using RAID.

Best regards! Smile

Hi,
thanks for reply.

Nah....it was an old machine. Dell inspiron 1420 laptop with 120G of single Sata SSD.

Plus the link you gave is like ubuntu 14.04. LL 5.X is based on ubuntu 20.04. not sure if that still applies.

Note - used LVM in setup for root disk.

Read the whole thread. It is exactely what was the point: Virtual drives raise this kind of error.
LVM is exactely this: Logical Volume Management. That means that the drive is managed as a logical drive, as opposed to a PHYSICAL drive.
Do a search on "Installing GRUB on LVM" or the like.

Good luck! Wink

Have you set up an LVM in each previous version of LL that you had this message?
I have LVM on my LL4.8 - I don't get prompted to press a key or that message - but I dont visually see grub load (i know its prolly there in the background). Although I did set up my partitioning outside of the install.

I am using Linux Lite 5.0 on both Dell Inspiron and on vms running on VMwrae as well as Oracle VirtualBox. And at all the places I am getting this message:

---
error: diskfilter writes are not supported.

Press any key to continue...
---

I am not using RAID but my root is on LVM. If I am using normal Ubuntu 18.04 LTS or 20.04 LTS, I never get this message but with Linux Lite its coming.

Even tried following the "quick_boot" parameter change as mentioned in: https://askubuntu.com/questions/468466/diskfilter-writes-are-not-supported-what-triggers-this-error#:~:text=This%20is%20a%20bug%20that,LVM%20or%20a%20RAID%20partition.

But thats still not working.

You may want to give the link below a read thru...
I assume the Installer configured the LVM for you? On my install I set up the partitioning/LVM prior then installed (I wanted the LVM different than what the installer defaulted) -- I don't have the error.. I have Root, Home and SWAP all on LVM on a single VG..

@firenice03

Using LL for 1st time.
Helped my nephew installing it (remotely) for his school assignments.
Used Default lvm that installer gave.

Also, seen a lot of LL folks complaining about same warning / error for various LL versions.

The bug was marked in the Ubuntu 14.04. Current version is Ubuntu 20.04. If I am installing with the default partition with the Ubuntu 20.04, I am not getting that error.
But with the default installer why I am getting the error with LL 5.0 ?

I can create the partition manually. But when the default installer can do the task why should I do that manually ?

There are various reasons for doing the partition manually. For starters, you may want to mount /home or /var on different partition.
I almost all time do partition manually.

I think this is LL specific issue. May be I will create issue on GitHub of LL.
