I got a VPS running Ubuntu 14.04.5 LTS:
# uname -a
Linux host.xyz 3.13.0-042stab123.9 #1 SMP Thu Jun 29 13:01:59 MSK 2017 x86_64 x86_64 x86_64 GNU/Linux
The kernel itself seems to support ext4:
# cat /proc/filesystems
nodev cgroup
nodev devpts
nodev mqueue
ext4
nodev nfs
nodev nfs4
nodev delayfs
nodev devtmpfs
nodev sysfs
nodev proc
nodev tmpfs
nodev binfmt_misc
nodev fusectl
nodev fuse
nodev rpc_pipefs
But mkfs does not:
# mkfs.
mkfs.bfs mkfs.cramfs mkfs.minix
I would like to format a partition as ext4 but apparently, the preinstalled image does not include the required executable. Is there any way to install it? If there is not, what is my best option?
