Hi All,<BR>
<BR>
I met below problem, would you help to tell me how to handle it?<BR>
<BR>
Now has two machine: A (primary), B (seconday)<BR>
I installed DRBD8.3.0 on these two machines.<BR>
<BR>
1) Now A is primary, B is seconday.<BR>
<BR>
2) B power off<BR>
<BR>
3) Then, on machine A, issue command "/sbin/drbdadm primary r0", and issue command "/bin/mount /dev/drbd0 /usr/local/fountain/database/xyz"<BR>
cat /proc/drbd<BR>
found its status is "primary/unknown"<BR>
It is reasonably.<BR>
<BR>
4) Now B power on.<BR>
On machine A, issue command:<BR>
"/sbin/umount /dev/drbd0" and "/sbin/drbdadm secondary r0".<BR>
<BR>
And then, on machine B, issue command:<BR>
"/sbin/drbdadm primary r0", and issue command "/bin/mount /dev/drbd0 /usr/local/fountain/database/xyz"<BR>
<BR>
5) Now problem occurs:<BR>
On machine B, "primary/unknown", on machine A, "secondary/unknown"<BR>
<BR>
And I do above procedure two times, the second time, it is just like above; at the first time, the DRBD status is proper.<BR>
<BR>
Would you help to explain this? <BR>
Any other command is needed to avoid this problem ?<BR>
<BR>
Best regards,<BR>
Edward<BR>
