I upgraded a working DRBD system (0.7.11) from Centos 4.1 (2.6.9-11.EL) to 4.2 (2.6.9-22.EL) and rebuilt DRBD without any problems. However, when I start DRBD I get the following: Starting DRBD resources: [ d0 ioctl(,SET_DISK_CONFIG,) failed: Invalid argument Lower device is already mounted. cmd /sbin/drbdsetup /dev/drbd0 disk /dev/hde1 internal -1 --on-io-error=detach failed! ***** The lower device (/dev/hde1) is not mounted and is a single drive. The master is running 0.7.11 on Centos 4.1. The rebuilt slave is running 0.7.13. I'm not sure where to go from here. Is this data corruption, bad build? I built a test drbd system running a similar configuration and all worked as expected. The master was running fedora w/ 0.7.11 and the rebuilt slave on the test configuration was running Centos 4.2 (drbd 0.7.13). # cat /proc/drbd version: 0.7.13 (api:77/proto:74) SVN Revision: 1942 build by root@<server name>, 2005-10-16 20:59:09 0: cs:Unconfigured # drbdsetup /dev/drbd0 disk /dev/hde1 internal -1 --on-io-error=detach ioctl(,SET_DISK_CONFIG,) failed: Invalid argument Lower device is already mounted. Thanks for your input.
