Hello all,
I'm new to the list :) I've benn using drbd on my company lan since
february, things vent well for a while.
Lately I had an hard disk failure on my secondary, the disk is dead an I
had to change it for a new one.
I have trouble to resync the primary and the secondary. I'm not sure
about the right procedure, here is wat I did:
- change the hardrive
- then mkfs.ext3 on /dev/hda4 on the secondary (I guess the mistake is
somewhere here)
- then restart drbd on primary and secondary.
Secondary disk is empty while primary is full but status is Consistent,
the need to sync in /var/log/messages is 0KB
What is the correct recovery procedure ? Do I have to rebuilt the both
hard drive from scratch, is there some meta data to earase somewhere
(couldn't find where).
I'll find below my current configuration, any help is appreciate
Regards,
Xav
