Raid 1 with mdadm, restarting causes full reconstruction
Hi all, I'm using mdadm to to a level 1 raid on two disks (obviously). When I take out disk A and immediately put it back in, it resyncs without a problem without a reconstruction. But if I restart with drive B at the helm, then put A back in after the restart, it does a full reconstruction on A even though nothing has changed. Any idea why this is? (My bitmap is set to internal). I know mdadm is complicated and I should be providing a lot more information, but any vague ideas?
