<div dir="ltr"><div><div>Hi,<br><br></div>I get occasionally an error when starting DRBD with a not synced peer. Error is rare and results in an unusable drive, but surprisingly the synchronization progresses, and the DRBD restart solves the problem. Seems like some kind of race condition.<br><br></div><div>As one can see from the logs below, there are 2 DRBD resources (data0, data1), where 2 nodes mirror each other (host1(primary:data0, secondary:data1), host2(primary:data1, secondary:data0)). The DRBD receivers keep restarting due to some error, but the synchronization progresses, and eventually will finish, drives will remain unusable though.<br><br></div><div>During this repeated error/restart/connect client reports following errors:<br><br>lk_bdev_save(/var/lib/drbd/drbd-minor-0.lkbd) failed: No such file or directory<br>lk_bdev_save(/var/lib/drbd/drbd-minor-1.lkbd) failed: No such file or directory<br></div><div><br><br><br></div><div>* Details:<br>- Linux Kernel: <br> Linux version 3.14.35-28.38.amzn1.x86_64 (mockbuild@gobi-build-64012) (gcc version 4.8.2 20140120 (Red Hat 4.8.2-16) (GCC) ) #1 SMP Wed Mar 11 22:50:37 UTC 2015<br><br>- DRBD:<br> drbd: initialized.
