And what a coincidence, before upgrading to 4.20-rc2 I enabled discard: # findmnt / TARGET SOURCE FSTYPE OPTIONS / /dev/mapper/cryptroot ext4 rw,relatime,discard # cat /proc/cmdline cryptdevice=...:cryptroot:allow-discards # cryptsetup status cryptroot /dev/mapper/cryptroot is active and is in use. ... flags: discards Plus I triggered fstrim manually at start: # systemctl status fstrim Nov 19 00:16:14 azat fstrim[23944]: /boot: 122.8 MiB (128716800 bytes) trimmed on /dev/nvme0n1p1 Nov 19 00:16:14 azat fstrim[23944]: /: 0 B (0 bytes) trimmed on /dev/mapper/cryptroot But what is interesting here is that it did not do any discard for the "/", hm (does ext4 did it for me at start?) -- You are receiving this mail because: You are watching the assignee of the bug.
