Well - had the same thing here (X4500, Q1 2007) 2-3 times couple of month ago. The 'too many errors' msg ringed some bells: do you remember the race condition problems in the marvell driver (IIRC especially late u3, u4) which caused many 'bad ...' errors in the logs? So I simply checked the drive in question (Q&D 2xdd over the whole disk and checked, whether an error occured). Since not a single error or bad performance I put it back and no wonder, it is still working ;-) ). Your situation might be different, but checking may not hurt - your disks might be a victim of an SW aka ZFS error counter...
