Hi All

[root@test ~]# uname -a
Linux test.testbox.com 2.6.9-67.0.0.0.1.ELhugemem #1 SMP Sun Nov 18 00:31:12 EST 2007 i686 i686 i386 GNU/Linux


I have created two logical partition in an extended partition as

[root@test ~]# fdisk -l /dev/sdb
Disk /dev/sdb: 17.1 GB, 17179869184 bytes
255 heads, 63 sectors/track, 2088 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Device Boot Start End Blocks Id System
/dev/sdb1 1 852 6843658+ 83 Linux
/dev/sdb2 853 914 498015 83 Linux
/dev/sdb3 915 976 498015 83 Linux
/dev/sdb4 977 2088 8932140 5 Extended
/dev/sdb5 977 1038 497983+ 83 Linux
/dev/sdb6 1039 1100 497983+ 83 Linux

But when i try to format any logical drive i get following

[root@test ~]# mkfs -t ext2 /dev/sdb6
mke2fs 1.35 (28-Feb-2004)
Could not stat /dev/sdb6 --- No such file or directory
The device apparently does not exist; did you specify it correctly?


Please help

Thanks

What are the permissions you see for /dev/sdX?

What is the output of cat /proc/partitions?

Run partprobe and then try again to create the filesystem.

A cheap approach would be to just reboot and see if it refreshes the disk changes.

Thanks a ton .. Just did the partprobe and it's done...
