Friends,
Just like Windows OS we have to format the partition in order to use it.
To format partition use following command
mkfs -t ext2 /dev/partitionname
[root@RedHat ~]# mkfs -t ext2 /dev/sdc1
mke2fs 1.45.4 (23-Sep-2019)
Discarding device blocks: done
Creating filesystem with 262144 4k blocks and 65536 inodes
Filesystem UUID: 1c737ddb-f8a0-411b-9b4b-7e943afdd408
Superblock backups stored on blocks:
32768, 98304, 163840, 229376
Allocating group tables: done
Writing inode tables: done
Writing superblocks and filesystem accounting information: done
mkfs -- Make file system
To use partition we need to mount it on some directory.
[root@RedHat ~]# df -h | grep sdc1
We can see /dev/sdc1 isn't listed . Now after mounting it will be listed.
Let's create directory "thisisnewpartition" & mount it there.
[root@RedHat adminji]# mkdir thisisnewpartition
[root@RedHat ~]# mount /dev/sdc1 thisisnewpart
[root@RedHat ~]# df -h | grep sdc1
/dev/sdc1 1008M 1.3M 956M 1% /root/thisisnewpart
Some do for rest all the partition
[root@RedHat ~]# df -h | grep thisisnewpar
/dev/sdc1 1008M 1.3M 956M 1% /root/thisisnewpart
/dev/sdc2 2.0G 3.0M 1.9G 1% /root/thisisnewpart2
/dev/sdc3 3.0G 4.5M 2.8G 1% /root/thisisnewpart3
/dev/sdc5 6.0G 12M 5.6G 1% /root/thisisnewpart5
/dev/sdc6 8.9G 21M 8.4G 1% /root/thisisnewpart6
/dev/sdc7 12G 30M 12G 1% /root/thisisnewpart7
Now go to thisisnewpart6 and copy directory /etc
cd / thisisnewpart6
[root@RedHat thisisnewpart6]# cp -rvf /etc *.
Note : Period "." means in current pwd
[root@RedHat thisisnewpart6]# du -sh *
25M etc
Now we can see 25 M of /etc
