Dear Maintainer, GNOME System Monitor (gnome-system-monitor) shows “Root partition” used space inflated when additional ext4 filesystems are mounted under /mnt and are backed by LUKS/dm-crypt (device-mapper) volumes. The inflated UI values do not match authoritative filesystem usage reported by `df`. Environment: - OS: Debian 13 (amd64), GNOME desktop - Kernel: 6.12.96+deb13-amd64 - gnome-system-monitor: 48.1-2 (stable) Storage layout (relevant): - `/` is ext4 on `/dev/mapper/debian--13--vg-root` (via LUKS → LVM) - `/mnt/data1` and `/mnt/data2` are separate ext4 mounts, each on a distinct `/dev/mapper/luks-*` (via LUKS → dm-crypt) Steps to reproduce: 1. Ensure `/` is mounted on LUKS+LVM ext4 (root). 2. Ensure two separate LUKS-backed ext4 filesystems are mounted under `/mnt/data1` and `/mnt/data2`. 3. Open GNOME System Monitor. 4. Increase used space on either/both `/mnt/data1` and `/mnt/data2`. 5. Observe the “Root partition” used value. Expected: - “Root partition” usage should reflect only the filesystem mounted at `/`. - Used space on `/mnt/data1` and `/mnt/data2` should not be attributed to `/`. Actual: - “Root partition” used space increases as if it includes used space from `/mnt/data1` and/or `/mnt/data2`. Authoritative filesystem usage evidence: - `df -h /`: /dev/mapper/debian--13--vg-root 448G 213G 213G 50% / - `df -h /mnt/data1/`: /dev/mapper/luks-* 458G 47G 388G 11% /mnt/data1 - `df -h /mnt/data2/`: /dev/mapper/luks-* 458G 110G 325G 26% /mnt/data2 Mount-to-device mapping evidence: - `findmnt -R / -o TARGET,SOURCE,FSTYPE | grep '^├─/mnt'`: - /mnt/data1 -> /dev/mapper/luks-* (ext4) - /mnt/data2 -> /dev/mapper/luks-* (ext4) Additional context: - In a Debian 13 GNOME VM where `/mnt/data` is just a plain virtual disk (no LUKS/dm-crypt/LVM layering), GNOME System Monitor reports root and the extra mount separately as expected. Would be happy to provide logs/screenshots if needed.
