Hi, I prepare two PCs for DRBD and duplicate /dev/sdb1 to each other by DRBD. But there are some data in PC1 /dev/sdb1 already. I issued 'drbdsetup /dev/drbd0 primary --do-what-I-say' at both PCs, and don't do 'mkfs -t ext3 /dev/drbd0' at PC1 for keeping old data, but do it at PC2. Reboot both PC and start DRBD and Heartbeat OK. Data of /dev/drbd0 will be replicated from PC1 to PC2. But: 1. The disk I/O performance of /dev/drbd0 is very poor. 2. I disconnect the network of PC1, then I get the error message at PC1: "Kernel panic: drbd0: Sorry, I have no access to goot data anymore." If I do 'mkfs -t ext3 /dev/drbd0' at PC1, DRBD will be OK after I disconnect the network of PC1 and well done. How can I make a good /dev/drbd0(/dev/sdb1) without clear old data of /dev/drbd0? (/dev/sdb1 is the physical disk partition used) regards, Longming 3/8
