Hi all,
 
I was wondering if I am missing something:
 
I am using Alma Linux 9.6 as hypervisor and linstor/drbd as primary storage 
(LVM thin pool).
I cannot discard / trim in guest VM (ubuntu 24 / ext4 file system):
 
fstrim -v /
fstrim: /: the discard operation is not supported
 
lsblk -D
NAME   DISC-ALN DISC-GRAN DISC-MAX DISC-ZERO
sr0           0                           512B                     0B         0
vda           0                          512B                      0B         0
└─vda1        0                      512B                     0B         0
 
Thin pool discard passdown is enabled.
In qemu xml: discard='unmap'
 
Are there any limitations?
Same setup but ubuntu24 as hypervisor it works out of the box.
 
Thank you!
