Re: some non critical problems... (1. mdadm segfault -> write-mostly, 2. smart?)

Umm... to reiterate one of my questions in above email:


     

quoted

md1 : active raid1 sdc1[3](W) sdb1[5](W)
       9767416 blocks super 1.0 [2/2] [UU]
       bitmap: 6/150 pages [24KB], 32KB chunk
       

Is it possible to disable that (W) --write-mostly flag? Does it
decrease performance or something, if both devices in the array are
set to (W) ?
     

this seems to have fixed it:

  mdadm --fail /dev/md1 /dev/sdb1
  mdadm --remove /dev/md1 /dev/sdb1
  mdadm --zero-superblock /dev/sdb1
  mdadm --add --readwrite /dev/md1 /dev/sdb1


   

Sorry for a late question, but in adding this to my notes, I realized I 
wasn't clear on why this flag moved to the other partitions. Are you, 
and if so can you clarify?
