Hi, Perhaps you might be able to solve this by using network block devices on which you use LVM. Have a look at drbd. I've used drbd fot fail-over purposes, but used straight filesystems. I am not sure if this will work, but suspect it very likely it will work. Just like LVM can also be installed on top of a md device. link for drbd: http://www.drbd.org Rick <BLOCKQUOTE dir=ltr style="PADDING-RIGHT: 0px; PADDING-LEFT: 5px; MARGIN-LEFT: 5px; BORDER-LEFT: #000000 2px solid; MARGIN-RIGHT: 0px"> <DIV style="FONT: 10pt arial">--------- Oorspronkelijk bericht -------- Van: "LVM general discussion and development" <linux-lvm@redhat.com> Naar: "linux-lvm@redhat.com" <linux-lvm@redhat.com> Onderwerp: [linux-lvm] HA Functionality for LVM Datum: 11/02/05 16:00 Hi there, i have the question if there is a ha functionality for lvm especially to activate one vg in excusive mode (like hp lvm). Or are there other ways to do this ? Any ideas?
