ACES01:~ # ls /dev/sdb /dev/sdb ACES01:~ # fdisk /dev/sdb Welcome to fdisk (util-linux 2.28). Changes will remain in memory only, until you decide to write them. Be careful before using the write command. Device does not contain a recognized partition table. Created a new DOS disklabel with disk identifier 0xedea1b84. Command (m for help): n Partition type p primary (0 primary, 0 extended, 4 free) e extended (container for logical partitions) Select (default p): p Partition number (1-4, default 1): 1 First sector (2048-33554431, default 2048): Last sector, +sectors or +size{K,M,G,T,P} (2048-33554431, default 33554431): 33554431 Created a new partition 1 of type 'Linux' and of size 16 GiB. Command (m for help): t Selected partition 1 Partition type (type L to list all types): 8e Changed type of partition 'Linux' to 'Linux LVM'. Command (m for help): w The partition table has been altered. Calling ioctl() to re-read partition table. Syncing disks. |
