Hi list, I have a SAN attached to a CentOS 4.2 server. I have expanded the size of the virtual disk within the SAN (by adding a new HD to the disk pool) and need CentOS to see the new size (CentOS see it as /dev/sdb). I'm using LVM. Do you know a method for the Volume Group to see that one of its harddisk is now bigger, without rebooting (it's not a problem with a reboot but since the LDAP directory is on this server, it is problematic). Thanks. kfx
