Hi,
on bullseye fstrim was working fine, but after the upgrade to bookworm fstrim stops working.
Setup is: ext4 on LUKS on LVM on SSD
# lsblk --discard
NAME DISC-ALN DISC-GRAN DISC-MAX DISC-ZERO
sda 0 512B 2G 0
├─sda1 0 512B 2G 0
└─sda2 0 512B 2G 0
└─sda2_crypt 0 0B 0B 0
├─volgrp-swap 0 0B 0B 0
├─volgrp-root 0 0B 0B 0
└─volgrp-home 0 0B 0B 0
Trimming the EFI partition (sda1) is fine, but trying to trim root or home results in:
fstrim: /: the discard operation is not supported
The command...
#dmsetup table /dev/mapper/sda2_crypt --showkeys
...doesn't show any allow-discard and because of this and the lsblk output I think it's cryptsetup/luks which is not working correctly here.
But the crypttab includes:
sda2_crypt UUID=[UUIDishere] none luks,discard
I've added "issue_discards = 1" to /etc/lvm/lvm.conf without success - and btw. that wasn't needed before the upgrade.
Any hints what to test or where to search for a solution?
regards

just checked and discards still work.

Sorry, my fault.

I'm using a script to decrypt this drive via SecureBoot+TPM so /etc/crypttab doesn't get used and this script doesn't use the allow-discard option by default and was resetted to default values with the upgrade to bookworm.
After patching the script, everything is fine for me. :-)
(btw, I have to repair my github repo ... somehow it's broken:
https://github.com/hede5562/mortar , fork of https://github.com/noahbliss/mortar
I mean, github is broken, but... okay... github is Microsoft now... eh!?)
