No it is not shared via NFS (do we have to first share it?) Problem is, there is no free slot for disks in our machine (say N1). However another node (say N2 which is running scientific linux independently) has free slots. So I added the physical disks to N2. the disk has been formatted and it has a mount point on N2.
Now I want to add N2:/dev/sdb to N1:/dev/tigerfiler1/tigervolume Can you please guide step by step?

A more common case would be to move some directories to /arch and use sym links. You could create a loopback diskfile somewhere on /arch and add that to LVM. It's going to make bootup messy, so you wouldn't want any volumes on it that are required for bootup (especially / or /usr or /sbin, and probably not /var) ... ________________________________ From: "Mahmood Naderan" <nt_mahm...@yahoo.com> >To: scientific-linux-users@fnal.gov >Sent: Wednesday, May 7, 2014 1:12:41 AM >Subject: Add a remote disk to LVM > > > > > >Hello, >Is it possible to add a network drive to existing LVM?
