Is it possible to find out when errors occurred on a RAID-Z other than just monitoring the output of "zpool status" regularly and looking for changes?
I have a RAID-Z that I just discovered has between 3 and 7 checksum errors on each of 7 disks. I want to know why disks that had worked without errors on ZFS since 6TB was a big disk have got such errors in the past couple of weeks. If I knew the date and time of the errors it might give me a clue. The system in question has 9*6TB and 9*10TB disks in 2 RAID-Z arrays. None of the 10TB disks had a problem while 7/9 of the 6TB disks reported errors. The 6TB disks are a recent addition to the pool and the 9*10TB RAID-Z was almost full before I added them, so maybe the checksum errors are related to which disks had the most data written. If I knew which day the errors happened on I might be able to guess at the cause. But ZFS doesn't seem to put anything in the kernel log.
