Disc upgrade - how to reread partition table?

[Macka Radek]

Just for info: really need reboot, maybe due to rootfs is active on
device ... 

Partprobe or hdparm are unable to re-read it :-(

dell2950a:~# hdparm -z /dev/sda
/dev/sda:
 BLKRRPART failed: Device or resource busy

Anyway thanks for your hints
Have a nice day
