[rhn-users] RHEL freeze: diskdump: -

[Honti Balázs]

Hello! I tried to use a spare 12G partition, after formatting with 
"diskdumpfmt -fpv /dev/hdb3" when it already seems to be OK:
[root at webplm /]# diskdumpfmt -cv /dev/hdb3
/dev/hdb3
 status     : formatted
 block size : 3000138
 version    : 1-1.1.9
 sample rate: 8
 block order: 2
 format size: 261787
 note       : parameters satisfied 

But after this I just got:
[root at webplm /]# diskdumpctl /dev/hdb3
diskdumpctl: /dev/hdb3 is not supported! 

What/how should I do? :-) It is a plain IDE partition... 

Thanks,
Honti,Balázs
