My home server is giving me fits. I have seven disks, comprising three pools, on two multi-port SATA controllers (one onboard the Asus M2A-VM motherboard, and one Supermicro AOC-SAT2-MV8). The disks range from many months to many days old. Two pools are mirrors, one is a raidz. The machine is running opensolaris snv99. Nearly every time I scrub a pool I get small numbers of checksum errors on random drives on either controller. I have replaced the power supply, suspecting bad power, to no avail. I removed the AOC-SAT2-MV8 and all the drives, save the root mirror, (to try ruling out some weird interaction with the AOC-SAT2-MV8) and still take errors. Has anyone had a similar problem? Any ideas what may be happening? Is there more data I can provide? Many thanks, Charles
