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,
