After replacing a bad disk and waiting for the resilver to complete, I started a scrub of the pool. Currently, I have the pool mounted readonly, yet almost a quarter of the I/O is writes to the new disk. In fact, it looks like there are so many checksum errors, that zpool doesn't even list them properly:
pool: p state: ONLINE status: One or more devices has experienced an unrecoverable error. An attempt was made to correct the error. Applications are unaffected. action: Determine if the device needs to be replaced, and clear the errors using 'zpool clear' or replace the device with 'zpool replace'. see: http://www.sun.com/msg/ZFS-8000-9P scrub: scrub in progress, 18.71% done, 2h17m to go config: NAME STATE READ WRITE CKSUM p ONLINE 0 0 0 raidz1 ONLINE 0 0 0 c2d0 ONLINE 0 0 0 c3d0 ONLINE 0 0 0 c5d0 ONLINE 0 0 0 c4d0 ONLINE 0 0 231.5 errors: No known data errors I assume that that should be followed by a K. Is my brand new replacement disk really returning gigabyte after gigabyte of silently corrupted data? I find that quite amazing, and I thought that I would inquire here. This is on snv_60.
