Linux Commands Part 19 -DELETE LINUX PARTITION

Friends,

As of now two partitions are mounted

[root@RedHat ~]# df -h | grep sdc

/dev/sdc1 1008M 1.3M 956M 1% /thisisnewpart

/dev/sdc6 8.9G 21M 8.4G 1% /root/thisisnewpart3

So if try to delete without unmounting then it will give error

Step 1 : unmount

[root@RedHat ~]# umount /dev/sdc1

[root@RedHat ~]# umount /dev/sdc6

[root@RedHat ~]# fdisk /dev/sdc

Be careful before using the write command.

The partition table has been altered.

The kernel still uses the old table. The new table will be used at the next reboot or after you run partprobe(8) or kpartx(8).
