[DRBD-user] Mount filesystem error and how to recover out-of-sync partition

[陈楠]

Hi all,
When our primary server power outage, our secondary server can not mount filesystem. We think that: filesystem has crashed. We know inode information, super block info, data block, metadata block are stored in partition. One of these is destroied will cause filesystem issue or drbd issue. Our filesystem was run above drbd partition. From log, we found that drbd report a out-of-sync message. We think this is the reason for Mount issue. Maybe our server supply service just now, we want to the server can recover from that issue. Can you give me some advice about drbd or application? Thank you! Our drbd version si 0.7.21.
