Dear Folks,
I am using DRBD 0.6.12 and have created a second drbd device on two
200MB raw disks. I am syncing data, and am copying data, and all was
going nicely until these messages began to appear in
/var/log/messages:
Nov 23 00:23:51 machine1 kernel: drbd1: tl messed up!
Nov 23 00:23:51 machine1 kernel: drbd1: Epoch set size wrong!!found=192 reported=191
Nov 23 00:23:51 machine1 kernel: drbd1: transferlog too small!!
What does this mean? Will I lose data? Is something configured
wrongly?
Note: heartbeat is monitoring the first device, but not the second, on
which these errors are being reported.
I am migrating from the first (full) device to the second (much
bigger) device.
The OS is Red Hat 7.3.
