Description franck.lemonnier 1999-12-31 12:45:34 UTC 
Hi,

during my Sparc Redhat 6.1 install, I do not assign the whole disk space. I
keep 1 Gb for later.

So, recently I need to allocate this disk space. So, I use fdisk to declare
a new partition but it complains about a 'device or ressource busy" ???

So, the operations I try to do :

[root@ors40428 ~]# fdisk /dev/hda

Command (m for help): p

Disk /dev/hda (Sun disk label): 15 heads, 63 sectors, 8892 cylinders
Units = cylinders of 945 * 512 bytes

   Device Flag    Start       End    Blocks   Id  System
/dev/hda1             0      4335   2048256   83  Linux native
/dev/hda2  u       4335      5202    409657+  83  Linux native
/dev/hda3             0      8892   4201470    5  Whole disk
/dev/hda4          5202      5757    262237+  82  Linux swap
/dev/hda5          5757      5974    102532+  83  Linux native

Command (m for help): n
Partition number (1-8): 6
First cylinder (4335-8892): 5974
Last cylinder or +size or +sizeM or +sizeK (5974-8892, default 8892): 8892

Command (m for help): p

Disk /dev/hda (Sun disk label): 15 heads, 63 sectors, 8892 cylinders
Units = cylinders of 945 * 512 bytes

   Device Flag    Start       End    Blocks   Id  System

/dev/hda2  u       4335      5202    409657+  83  Linux native
/dev/hda3             0      8892   4201470    5  Whole disk

/dev/hda6          5974      8892   1378282+  83  Linux native

Command (m for help): w
The partition table has been altered!

Calling ioctl() to re-read partition table.
Syncing disks.
Re-read table failed with error 16: Device or resource busy.
Reboot your system to ensure the partition table is updated.

What's the matter whith fdisk ?

NB: The workstation is an Ultra 5. I try using fdisk in single user mode
but the same problem happens.

You have other partitions from that hard disk already mounted or in use by your
system, so the kernel partition table for the disc can not be updated. The data
has been written to disk, but you need to reboot for changes to take effect. Or
alternatively, umount everything before modifying the partition table.
