[NCLUG] sw raid, recovery after install

[Matt Rosing]

Hi,

I added a raid 5 to my computer with 3 identical drives. I mounted it. I 
moved files to it. It looks like it's working. Then I looked at 
/proc/mdstat and it says it's recovering:

-------------
root at phoenix:/var/log# cat /proc/mdstat
Personalities : [raid6] [raid5] [raid4]
md0 : active raid5 sdb[0] sdd[3] sdc[1]
       2930274304 blocks super 1.2 level 5, 512k chunk, algorithm 2 
[3/2] [UU_]
       [========>............]  recovery = 40.6% (595347620/1465137152) 
finish=235.8min speed=61467K/sec

unused devices: <none>
-----------

Is it normal to be recovering a disk right after the raid is created? It 
could very well be that I set it up incorrectly.

Thanks,

Matt
