Hi All, We have an OSA setup. When I check the usage of filesystem of any container using "df" command, it shows the lvm partitions of the underlying host as well as shown below: -- Filesystem Size Used Avail Use% Mounted on /dev/mapper/lxc1-lv_root 86G 60G 22G 74% / none 492K 4.0K 488K 1% /dev /dev/mapper/lxc-openstack 493G 136G 334G 29% /var/log tmpfs 252G 0 252G 0% /dev/shm tmpfs 51G 88K 51G 1% /run tmpfs 5.0M 0 5.0M 0% /run/lock tmpfs 252G 0 252G 0% /sys/fs/cgroup example:gfs-repo 86G 67G 16G 82% /var/www/repo --- How to exclude the host partitions such that df only reports the container usage only ? Thanks Kumar
Hi, I don't think this is possible. Disk usage of containers should be performed from the host rather then container. Unfortunately, with current default backing store (which is `dir`), there's no neat way of doing that. So you'd need to use smth like `du -sh /var/lib/lxc/<container_name>/rootfs/` to check how much diskspace it's consuming. Though, backing store is customizable. So you can set `lxc_container_backing_store` variable to "lvm" or "zfs" and check diskspace consumption per lvm/zfs volume. пн, 5 июн. 2023 г. в 09:56, Gk Gk <ygk.kmr@gmail.com>:

How to exclude the host partitions such that df only reports the container usage only ?
Thanks Kumar
But when I check it from the host, it is still showing incorrect usage: --- du -sh /var/lib/lxc/example_repo_container-237946ab/rootfs/root/ 36K /var/lib/lxc/example_repo_container-237946ab/rootfs/root/ -- How to get its correct usage then ?

I think it's the correct usage. You're just checking the size of `/root` folder inside the container, rather than the container overall. As it should be `du -sh /var/lib/lxc/example_repo_container-237946ab/rootfs/` instead. пн, 5 июн. 2023 г. в 14:12, Gk Gk <ygk.kmr@gmail.com>:
