Christian,

I have modified a partition with fdisk.
Then, I have tried to update the in memory partitioning informations, 
but I have the following error message :

# hdparm -z /dev/hdb

/dev/hdb:
BLKRRPART failed : Device or resource busy

An other partition is used on the same disk.

Regards,
Remi
