Din pacate conform documentatiei nu face ce vroiam exact (cand un host modifica "ceva" pe FS, celelalte host-uri sa fie aware de modificare) http://tldp.org/HOWTO/LVM-HOWTO/x1232.html "12.2. Sharing LVM volumes LVM is not cluster aware Be very careful doing this, LVM is not currently cluster-aware and it is very easy to lose all your data. If you have a fibre-channel or shared-SCSI environment where more than one machine has physical access to a set of disks then you can use LVM to divide these disks up into logical volumes. If you want to share data you should really be looking at GFS or other cluster filesystems. The key thing to remember when sharing volumes is that all the LVM administration must be done on one node only and that all other nodes must have LVM shut down before changing anything on the admin node. Then, when the changes have been made, it is necessary to run vgscan on the other nodes before reloading the volume groups. Also, unless you are running a cluster-aware filesystem (such as GFS) or application on the volume, only one node can mount each filesystem. It is up to you, as system administrator to enforce this, LVM will not stop you corrupting your data."
