It does look like you posted this after rebooting your RG a few hours ago. The reconnect always produces some errors, but that's to be expected.
What you mainly seem to have now is 'Corrected Blocks'. Although this sounds like an issue, it usually isn't one - the system's done its job and corrected problems in the blocks of data. Some (or a lot) of them might have been caused by the reboot.
What you might want to do is to reset the statistics on the RG (»home/xslt?PAGE=C_1_0
) to clear off any errors produced by the reboot and then wait a while (couple of hours or days) before checking to see if you have any problems that need attention.
