I have an ec2 instance with docker.
By default, the docker disk limit is 10 G but I need to have at least 20-30 G to investigate some issues.
For that I increased the
/dev/mapper to 100 G and
/dev/nvme0n1p1 (the ec2 disk space) to 30 G.
df -h --total
Filesystem Size Used Avail Use% Mounted on /dev/mapper/docker-259:4-xxxxxx-xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx 98G 11G 83G 12% / tmpfs 64M 0 64M 0% /dev tmpfs 1.9G 0 1.9G 0% /sys/fs/cgroup /dev/nvme0n1p1 30G 1.9G 28G 7% /etc/hosts shm 64M 0 64M 0% /dev/shm total 130G 13G 112G 11% -
/dev/mapper goes over 10 G, the mount becomes read-only and it becomes impossible to do anything, exactly as before increasing the disk limit.
Any idea on why this is happening? What should I do?
