Oops, what does (F) in /proc/mdstat means ??

[Thomas Scholten]

Hi All,

a recently typed less /proc/mdstat showed the following:

less /proc/mdstat
Personalities : [linear] [raid0] [raid1] [raid5]
read_ahead 1024 sectors
md0 : active raid5 sde1[3] sdd1[2] sdc1[1](F) sdb1[0] 5810304 blocks level
5, 64k chunk, algorithm 2 [4/3] [U_UU]
                                                      -----------
unused devices: <none>

Can anyone tell me what the (F) after "sdc1[1](F)" means ? Hope it has
nothing to do with Failure :-/

greetings from germany

Tom
