In my cluster(node1/node2) with drbd, the state in /proc/drbd is primary/secondary up2date/up2date, but when I change primary to node2 , the file that existed on node1 can not be found on node2. Then I do "drbdadm verify drbd0" to verify and resync the data, node2's data returned to be OK.
I am wondering how the problem occurs and how I can avoid it? BTW: I build a PV/VG/LV on drbd0, and drbd0 is built on a LV too. Is this the reason? Thanks.
