Hi,all: I created a raid5 array which consists of 15 disks, before recovering is done, a power failure event occured. After power is recovered, the machine box started successfully but "cat /proc/mdstat" gave no message, previously created raid5 was gone. I check kernel messages, it is as follows: <snip> bonding: bond0: enslaving eth1 as a backup interface with a down link. svc: failed to register lockdv1 RPC service (errno 97). rpc.nfsd used greatest stack depth: 5440 bytes left md: md1 stopped. iSCSI Enterprise Target Software - version 1.4.1 </snip> In normal case, md1 should bind its disks after printing "md: md1 stopped", then what happened in this cituation? BTW, my kernel version is 2.6.31.6. -- The simplest is not all best but the best is surely the simplest! -- To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
