I installed a new 160gig drive into my DELL running RHEL 3. I went into the setup utility/bios and enabled drive 2. I have 4 partitions on the sda boot drive. I did an fdisk and created 1 extended partition using the entire drive. When I run mkfs I get this error mke2fs 1.32 (09-Nov-2002) mkfs.ext3: No such device or address while trying to determine filesystem size [root@host1 root]# fdisk -l /dev/sdb Anyone have any ideas??? Do I need to format this drive first for use with Linux? How do I do that? Thanks Dave Martini LLNL Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System /dev/sda1 * 1 127 1020096 83 Linux /dev/sda2 128 1019 7164990 83 Linux /dev/sda3 1020 1274 2048287+ 82 Linux swap /dev/sda4 1275 14000 102221595 83 Linux [root@host1 root]# fdisk /dev/sdb The number of cylinders for this disk is set to 19452. 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, 160000000000 bytes 255 heads, 63 sectors/track, 19452 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System /dev/sdb1 1 19332 155284258+ 5 Extended Command (m for help): q [root@host1 root]# mkfs -t ext3 /dev/sdb1 mke2fs 1.32 (09-Nov-2002) mkfs.ext3: No such device or address while trying to determine filesystem size [root@host1 root]# fdisk -l /dev/sdb Disk /dev/sdb: 160.0 GB, 160000000000 bytes 255 heads, 63 sectors/track, 19452 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System /dev/sdb1 1 19332 155284258+ 5 Extended -- redhat-list mailing list unsubscribe mailto:redhat-list-request@xxxxxxxxxx?subject=unsubscribe https://www.redhat.com/mailman/listinfo/redhat-list
