...re going to share/export the same disk. The idea is not to have a single point of failure on the machine exporting the storage. For concept testing I am using one machine on which I have configured 2 GNBD exports, which are exporting exactly the same disk. These are configured with: # /sbin/gnbd_export -d /dev/sdb1 -e gnbd0 -u gnbd # /sbin/gnbd_export -d /dev/sdb1 -e gnbd1 -u gnbd They are exporting with the same id, so the multipath driver will automatically configure them as alternative paths to the same storage. Now on one of the cluster nodes used for running services I am importing...

Hey, I am trying to migrate Xen VM from 1 physical m/c to another. I have instll GNBD and done the following. VM1 to be exported: nbd_serv -n service gfs stop gnbd_export -c -d /dev/sda1 -e global_diskVM1 gnbd_export -l Domain 0 of other machine: depmod -a modprobe gfs modprobe gnbd modprobe lock_dlm service gfs start gnbd_import -i <ip adress of VM1> -n cd /dev/gnbd I see the global_diskVM1 in /dev/gnbd/ of Domain 0 of the other machine. When I try and m...

Wondering if anyone can point me in the right direction for automating the whole gnbd process. Thanks in advance i.e gnbd_serv gnbd_export gnbd_import modprobe gnbd _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

...r is a dell power edge 2850 with an attached power vault. The power vault's file systems are all gfs. I would like to export these to a second server via gnbd. I realize I *could* use nfs, which we do use elsewhere, but I was interested in figuring out gnbd. On the file server if I run gnbd_export -d /dev/vg_home/lv_home -e home Then on the other server modprobe gnbd and then run gnbd_import -i fileserver the devices get created can be mounted etc (well I might need to modprobe gfs before mounting) Anyways, what's the "correct" way of having this happen on boot? I've b...

Hello all: I'm having a strange problem with GNBD and LVM on two fully updated CentOS 5.5 x86_64 systems. On node1, I have exported a gnbd volume. lvcreate -L 500M -n mirrortest_lv01 mirrorvg gnbd_serv gnbd_export -d /dev/mirrorvg/mirrortest_lv01 -e node1_lv01 On node2 I have imported the volume: gnbd_import -i node1 Next, on node2 I attempt to create a mirrored LV with the imported GNBD volume and a local disk: fdisk /dev/gnbd/node1_lv01 then create an LVM partition fdisk /dev/sdb then create...
