Find out what filesystem a file or directory is part of
I have a lot of filesystems:
-
/
on a PCI-E SSD -
swap
on a SATA SSD -
/media/ned
is a RAID5 array -
/tmp
lives on RAM - Parts of
/home/oli
are symlinked and bind-mounted in fromned
- I also have
/media/jeff/
which is RAID1 that I store backups and bind-mount~/.wine
in off.
It's actually a lot more complicated than that. There are all sorts of extra symlinks that I need to untangle in the long run but for now I just need a nice way of taking a path and finding out where it physically lives.
This is not probably the best or the correct answer, but df can do it:
javier@todocolor:~$ df /boot/grub/
S.ficheros Bloques de 1K Usado Dispon Uso% Montado en
/dev/sda2 918354 184202 685154 22% /boot
javier@todocolor:~$ df .
S.ficheros Bloques de 1K Usado Dispon Uso% Montado en
/dev/md0 75532064 13930424 57795044 20% /
Take the first and the last column.
df /path/to/filename # to find out what device a file or folder is on
