Disc upgrade - how to reread partition table?

[Macka Radek]

Hi Andrey,

 

               Fdisk/parted shows the old size of /dev/sda disc (HW RAID virtual disc). Need somehow inform a kernel about new size of /dev/sda disc L

 I have there lvm used over /dev/sda, so resizing is not so big problem for me.

 

Regards

/Radek

where are you not seeing it enlarged? 

  

ext2/3 FS needs to be resize2fs'd, and fsck'd prior to, but you'd see the change in fdisk first.

Hello guys, 

 

               Some easy question for guru`s: 

 I`ve received new hdd into poweredge server, succesfully enlarge the RAID virtual disc BUT I do not know whether I am able (without rebooting) reread partition table under Debian Etch? Is it possible (and how)? 

sfdisk –R did not help me L it still shows the former size of disc. 

 

Thanks for hints 

Kind Regards
