Subject: Rereading disk geometry without reboot
Date: Mon, 6 Dec 2004 14:23:56 -0600	[thread overview]
Message-ID: <20041206202356.GA5866@thumper2> (raw)

I am using linux kernel 2.6.9 on a san.  I have file systems on
non-partitioned disks.  I can resize the disk on the SAN, reboot and grow
the XFS file system those disks.  What I would like to avoid rebooting or
even unmounting the filesystem if possible.

Is there any way to get the kernel to re-read the disk geometry and change
the information it holds without rebooting or reloading the module (which is
as bad as a reboot in my case)?

Thanks,

Andy
