Hello, I have created lxc and and storage type is "directory".


root@server:~# df -h Filesystem Size Used Avail Use% Mounted on /dev/loop0 7.8G 3.8G 3.7G 51% / /dev/loop1 3.6T 3.3T 132G 97% /storage none 492K 4.0K 488K 1% /dev tmpfs 16G 0 16G 0% /dev/shm tmpfs 6.3G 88K 6.3G 1% /run tmpfs 5.0M 0 5.0M 0% /run/lock

I'd like to reduce reserved space to 1% with following command but doesnt work.
root@server:~# tune2fs -m1 /dev/loop1 tune2fs 1.46.5 (30-Dec-2021) tune2fs: No such file or directory while trying to open /dev/loop1 Couldn't find valid filesystem superblock.

How can I achieve that?
