[geeks] Linux LVM on iSCSI question

[Patrick Giagnocavo]

So I am looking at a Linux-oriented VM clustering solution.  They
recommend that when using iSCSI as shared storage, that you set up LVM
on it, and mount the iSCSI LUN on both machines in order to enable live
migration.

Aren't there dangers in having 2 hosts both mount the same LUN?  How
does LVM avoid causing filesystem corruption in such a case?

I am not able to find much documentation talking about this -- anyone
have any iSCSI or LVM experience to share?

Cordially
