I have a 10 severs or so running SW raid.. After testing the |
| 4 |
write-intent bitmap for some time on one sver, i decided to use it on |
| 5 |
all of them. |

On one sever i try and create the bitmap: |
| 11 |
|
| 12 |
# mdadm --grow --bitmap=internal /dev/md1 |
| 13 |
mdadm: Cannot reliably determine size of array to create bitmap - sorry. |
| 14 |
|
| 15 |
# cat /proc/mdstat |
