ZFS Checksum Errors on Resilver
I'm currently running into a situation where one drive has gone offline due to too many errors, and one of my spares has been pulled in to my ZFS pool and ZFS is attempting to resilver onto that disk. However, there are checksum errors being generated on the spare disk during the resilver process. The resilver has now moved on to a second spare disk that it is attempting to use, and is, again, hitting checksum errors. I'm pretty sure I don't have three bad drives, and all of the rest of the drives in the pool (three others) are attached to the same FC connection and are not experiencing the same checksum errors.
This all started when my storage controller decided to reboot itself a few times, so I don't know if the pool needs a scrub or what. I'm half afraid to do the scrub for fear that it will find more "errors" and attempt to take ever more drives offline, which would be very bad for my data. Any suggestions on getting rid of these checksum errors, since I'm sure it isn't the drive, the storage controller, or the FC bus causing it? Something internal to ZFS...
Thanks,
Nick
