(I have DRBD running on a pair of IDE/PATA disks and no SATA drives in either system.) I partitioned my disks with fdisk. I have identical drives with identically sized partitions. I compiled the DRBD module, started DRBD, mounted /dev/drbd0 (not /dev/hda4), and formatted drbd0 with an ext3 file system on the primary only after I got DRBD up and running months ago. My logs did not start recording these errors until several weeks ago. Changes to my system over the last few months include only: (1) compiled a new kernel, new DRBD module (same 8.0.6 version, though) a couple of months before these errors began. (2) I have updated a number of other software packages on my system but none that I thought would affect my block devices or DRBD. Would upgrading my UDEV software cause these problems?
