hello: I recently added additional 160GB disk to my F8 system. and partitioned it as a single partition. but when I use "df" command to show my disk, it only show the size is 9.2G on my Desktop. GNOME it can show the disk as 149.0Gb correctly. how to fix this problem? the following is my disk info. --------------------------------------------------------------------- [root@pc1 ~]# df Filesystem Type Size Used Avail Use% Mounted on /dev/sda7 ext3 38G 15G 22G 41% / tmpfs tmpfs 474M 12K 474M 1% /dev/shm /dev/sda9 ext3 66G 61G 1.3G 98% /home /dev/sda5 vfat 25G 18G 7.1G 72% /media/disk /dev/sdb1 ext3 9.2G 5.3G 3.5G 61% /media/disk-1 /dev/sda1 vfat 15G 8.3G 6.4G 57% /media/disk-2 /dev/sda6 ext3 38G 3.9G 33G 11% /media/_home [root@pc1 ~]# fdisk /dev/sdb The number of cylinders for this disk is set to 19457. There is nothing wrong with that, but this is larger than 1024, and could in certain setups cause problems with: 1) software that runs at boot time (e.g., old versions of LILO) 2) booting and partitioning software from other OSs (e.g., DOS FDISK, OS/2 FDISK) Command (m for help): p Disk /dev/sdb: 160.0 GB, 160041885696 bytes 255 heads, 63 sectors/track, 19457 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk identifier: 0xe2c5e2d5 Device Boot Start End Blocks Id System /dev/sdb1 1 19457 156288321 83 Linux Command (m for help): q [root@pc1 ~]# ------------------------------------------------------------------ thanks, zhu
