I would start by performing a consistency check to make sure the backing devices on both sides are consistent. Make sure you're mounting the resource (/dev/drbd*) and not the resource's backing device (/dev/sd* or /dev/md* or /dev/disk/*, for example). Make sure both nodes are running OS versions and kernels that support the filesystem (ext4). Make sure the resources on both sides are configured for the same IP addresses and ports, so that you're not accidentally connecting two different resources (though the metadata should prevent this under any sane circumstances). If you suspected a network data integrity problem (faulty network card or driver), you could try enabling data-integrity-alg to test it, but do not leave that setting on in production. That's all I can think of as generic suggestions. Knowing more about the installed environment and your configuration may help. -- Nelson Hicks Network Operations SOCKET (573) 817-0000 ext. 210 nelsonh at socket.net On Tue, 2014-09-23 at 10:24 +0000, Tiaan Wessels wrote: > Hi, > I have a DRBD cluster with 2 nodes.
