a few days ago my raid5 had an crash. i replaced the hdd and add the wrong device to the raid (i add the device and not the partition)
Now the raid seems to work with follow config:
md0 : active raid5 sde1 sdd1 sdc sdb1 sda1 7814051840 blocks super 1.2 level 5, 512k chunk, algorithm 2 [5/4] [UU_UU] [>....................] recovery = 1.0% (20819448/1953512960) finish=865.7min speed=37205K/sec
My question is what happend to sdc? why it's important first to create a FD partition and to add sdc1 instead of sdc?
What could happend with my configuration?
