Hi,

one more thing I see right now:

mdadm --examine-bitmap for sd[ab]2

mdadm --examine-bitmap /dev/sda2
        Filename : /dev/sda2
           Magic : 6d746962
         Version : 4
            UUID : 54db81a7:b47e9253:7291055e:4953c163
          Events : 2772
  Events Cleared : 2772
           State : OK
       Chunksize : 512 KB
          Daemon : 5s flush period
      Write Mode : Normal
       Sync Size : 312464000 (297.99 GiB 319.96 GB)
          Bitmap : 610282 bits (chunks), 0 dirty (0.0%)

mdadm --examine-bitmap /dev/sdb2
        Filename : /dev/sdb2
           Magic : 6d746962
         Version : 4
            UUID : 54db81a7:b47e9253:7291055e:4953c163
          Events : 2772
  Events Cleared : 2772
           State : OK
       Chunksize : 512 KB
          Daemon : 5s flush period
      Write Mode : Normal
       Sync Size : 312464000 (297.99 GiB 319.96 GB)
          Bitmap : 610282 bits (chunks), 22506 dirty (3.7%)

Is it the last line a bit strange?
And this is somehow persistent, i.e. after consecutive
"examinations" the dirty status of sdb2 does not
change, while sda2 goes a little bit up and down.

This, BTW, is after a reboot, so a "clean" machine,
and without "smartd".

bye,
