I use external meta-disk. Disk and meta-disk are LVM volumes and blocks
are used by VPSs running below kvm/libvirt/qemu.
Some of my guest VPS show errors like this:
Jul 7 09:09:51 webx kernel: [28863.199248] EXT4-fs warning (device
vda1): ext4_end_bio:317: I/O error writing to inode 1050005 (offset 0
size 0 starting block 4871811)

vda1, logical block 4871555

*that* is something else,

I can confirm the above error is NOT related to DRBD. I removed the
drbd configuration of one of my guests and configured it to access
directly the lvm volume and the error still occours at random time.
I am still working on solving this problem.<br>
