Hi, I installed RHEL 6.0 OS on vmware with CREATE CUSTOM LAYOUT option. And I gave the space to different mount points as mentioned below: / 15360MB /boot 200MB /tmp 3072 MB swap 1024 MB. fdisk -cul command shows the disk size as 64.4 GB. But when I try to create partion of 10 GB with fdisk -cu command, it says "value out of range". When I created the partition with maximum possible space, it created the partion of 999 KB. My question is where the remaining 40 GB space gone. And how can I create the partition of 10 GB space ? Please see the sequence of the commands below: [root@gauravclient Desktop]# fdisk -cul Disk /dev/sda: 64.4 GB, 64424509440 bytes 255 heads, 63 sectors/track, 7832 cylinders, total 125829120 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x0007fb86 Device Boot Start End Blocks Id System /dev/sda1 * 2048 411647 204800 83 Linux /dev/sda2 411648 31868927 15728640 83 Linux /dev/sda3 31868928 36063231 2097152 83 Linux /dev/sda4 36063232 125829119 44882944 5 Extended /dev/sda5 36067328 38164479 1048576 82 Linux swap / Solaris [root@gauravclient Desktop]# df -h Filesystem Size Used Avail Use% Mounted on /dev/sda2 15G 2.3G 12G 16% / tmpfs 504M 100K 504M 1% /dev/shm /dev/sda1 194M 24M 161M 13% /boot /dev/sda3 2.0G 68M 1.9G 4% /tmp /dev/sr0 2.8G 2.8G 0 100% /media/RHEL_6.0 i386 Disc 1 [root@gauravclient Desktop]# [root@gauravclient Desktop]# fdisk -cu /dev/sda Command (m for help): n First sector (36065280-125829119, default 36065280): Using default value 36065280 Last sector, +sectors or +size{K,M,G} (36065280-36067327, default 36067327): +10G Value out of range.
