Linux how to determine the file system type
In Linux all file-systems mount points are mounted within in / mount points,but we could have different file-systems type within / as per requirements and usages.These file-systems could mount and work on various devices that detected on Linux operating system and file-systems support is depend on Linux kernel modules that are essential to work on these file-systems.So this post we will see In Linux how to determine the file system type.
In Linux OS, how could we find out file-systems type, through df -T command.
[root@srv1 ~]# df -T Filesystem Type 1K-blocks Used Available Use% Mounted on /dev/mapper/VolGroup-lv_root ext4 17971068 8043560 9007956 48% / tmpfs tmpfs 1962196 59432 1902764 4% /dev/shm /dev/vda1 ext4 487652 138022 324030 30% /boot /dev/vdb1 xfs 4184016 32928 4151088 1% /var/ftp/pub
In above command output, we can see we have file-system type used to mount Disk partitions.
We can also use to see this piece of information through mount command, which is used to see all mounted partitions
[root@srv1 ~]# mount /dev/mapper/VolGroup-lv_root on / type ext4 (rw) proc on /proc type proc (rw) sysfs on /sys type sysfs (rw) devpts on /dev/pts type devpts (rw,gid=5,mode=620) tmpfs on /dev/shm type tmpfs (rw) /dev/vda1 on /boot type ext4 (rw) none on /proc/sys/fs/binfmt_misc type binfmt_misc (rw) none on /sys/kernel/config type configfs (rw) /dev/vdb1 on /var/ftp/pub type xfs (rw)
So with this above outputs , now we know mount command could also provide information regarding file-system mount point.
Although in Linux there are many commands to know file-system type of mounted point points, but let’s cover another commands lsblk used in Linux for various reasons to know Disk information.
[root@srv1 ~]# lsblk -f NAME FSTYPE LABEL UUID MOUNTPOINT vda ├─vda1 ext4 efe9ff3b-2a96-4378-8b61-9a3273fa32d3 /boot └─vda2 LVM2_member u3xScx-ZjL0-U8Ul-BWV0-kkEZ-muvR-8AAe0Y ├─VolGroup-lv_root (dm-0) ext4 e2a912a3-f747-4e79-af53-14fc93637dd7 / └─VolGroup-lv_swap (dm-1) swap 65988ff1-e79c-414c-8720-6eed05aeb5e6 [SWAP] vdb └─vdb1 xfs 5e28db70-2231-428c-9dac-3afb25199bbb /var/ftp/pub [root@srv1 ~]#
This above command output also have information about mount point file-system type.
In this post , now we know we have many commands in Linux to know file-system type of mount point.
