I would like to know if it's possible to check which filesystems my kernel supports. (like btrfs, raiserfs, exfat, ...).

Man mount shows many options, but it's not really possible to use all

You can easily find out what filesystem running Linux kernel supports with following command:

 cat /proc/filesystems

Nice answer! A greener answer would have been to post the text output of the command :). – rosch Oct 18 '12 at 12:35


cat /proc/filesystems

to check the list of file systems supported by the kernel.

Note that file systems like btrfs may be available but they are also experimental, so use with caution.

Thanks for info! BTRFS looks faster than EXT4, but I am recieving some errors in dmesg. – gsedej Oct 13 '12 at 10:56
