The Gnome problem with btrfs

[Leslie S Satenstein <lsatenstein yahoo com>]

Some notes for you during the posting of the gnome reported crash.  As I stated, the same identical software installed on this same system with ext4 file system does not crash, does not cause all this research

Below my signature is a body of a gnome report. I also added the grub.cfg and the /etc/fstab

In reading some of the Reports, it appears that there is a wrong field type being detected for some of the crashes.

Here is what I did frequently experience (only with btrfs). I have an extension with a few fields similar to the following.

[0][-][+]

I usually want the field to have the value 28.  It is a pixal padding value for the display fields.  I can click normally on the [+] and suddently (again, only with btrfs), I get a full lockup--no keyboard activity possible, monitor is gray, and mouse is dead.   On reboot, the [0] contains 1000, (the upper limit of the value within the compiled schema).

Other times, its a blowup for a non boolean value in a field (again, only with btrfs. I can even crash gnome-tweak-tool). 

PLEASE NOTE, ext4 file system does not blow up or cause problems. It has been a one month venture for me because first level support (bugzilla), is saying its one of my installed software. If it is an extension provided by Fedora (sudo dnf install ...) or from the website, the gnome-shell should be adequately sandboxed.

I was concentrating on the use of btrfs for my SSD, as "copy on write" does comparitively less I/O than ext4 or xfs alternatives.  and thus less need to frequently run fstrim.  I would like to use btrfs for the SSD, but will not until this crashing problem is resolved.

I test on a real system, not with VM. I have 2 "one terrabyte" disks set aside for booting, testing, scrubbing, etc.

Here are my bug report numbers since I started in end August

BUG 1390198  crash on first login.
BUG 1390198  Gnome Shell dies. Still open
Bug 1458505  root logon system-tray users icon crashes system-tray

BUG 1469129  btrfs full lockup
BUG 1496283  gnome bugzilla  btrfs

Please note. I am the messenger, not the cause

The first application after the static screen appears causes the abort.
One test -- firefox
Test 2      -- writer

This report is from a btrfs system.

I cannot generate this abort with the identical setup on ext4 system.

A copy of the grub.cfg follows.  You can see my 5 disks and their setup.
Following the grub.cfg is my /etc/fstab

Subject: Re: Fw: Gnome extensions

I also have not seen any issues like this, and have been using btrfs with GNOME
for atleast a couple of years, on Ubuntu and Gentoo.
