Hello, list and Merry Christmas to all I am facing some weird checksum errors during scrub. The configuration is the following: Board: Supermicro Motherboard X10DRi-T4+ ( http://www.supermicro.com/products/motherboard/xeon/c600/x10dri-t4_.cfm) Controller: LSI SAS 9300-8i ( http://www.lsi.com/products/host-bus-adapters/pages/lsi-sas-9300-8i.aspx) HDD: 21X6TB Western Digital WD60EFRX HDD: 2XIntel SATA 600GB Solid-State Drive SSDSC2BB600G401 DC S3500 (SWAP, ZIL, CACHE) Chassis: Supermicro 847BE1C-R1K28LPB 4U Storage Chassis RAM: 64 GB I installed initially FreeBSD 10.1-RELEASE created one pool consistent by 3 X7disk VDEVs in RAIDZ3. I used NFS to start copying some data. After copying around 3TB I initiated a scrub. The result was the following: http://pastebin.com/rswgCY2A and http://pastebin.com/DQ2urGXk I tried to flash the controller but the LSI utility did not recognize the controller. I installed FreeBSD 9.3-RELEASE and used LSI's mpslsi3 driver. I was able to flash the latest bios and firmware that way.

After 3 TB of data I started a scrub and I am still getting checksum errors though there are no messages regarding the drives anymore in /var/log/messages pool: Pool 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://illumos.org/msg/ZFS-8000-9P scan: scrub in progress since Thu Dec 25 08:46:21 2014 2.28T scanned out of 5.54T at 816M/s, 1h9m to go 11.9M repaired, 41.26% done config: NAME STATE READ WRITE CKSUM Pool ONLINE 0 0 0 raidz3-0 ONLINE 0 0 0 gpt/WD-WX41D94RN5A3 ONLINE 0 0 15 (repairing) gpt/WD-WX41D948YE1U ONLINE 0 0 14 (repairing) gpt/WD-WX41D94RN879 ONLINE 0 0 16 (repairing) gpt/WD-WX21D947NC83 ONLINE 0 0 24 (repairing) gpt/WD-WX21D947NT77 ONLINE 0 0 15 (repairing) gpt/WD-WX41D948YAKV ONLINE 0 0 19 (repairing) gpt/WD-WX21D9421SCV ONLINE 0 0 20 (repairing) raidz3-1 ONLINE 0 0 0 gpt/WD-WX21D9421F6F ONLINE 0 0 16 (repairing) gpt/WD-WX41D948YPN4 ONLINE 0 0 14 (repairing) gpt/WD-WX21D947NE2K ONLINE 0 0 22 (repairing) gpt/WD-WX41D948Y2PX ONLINE 0 0 19 (repairing) gpt/WD-WX41D94RNAX7 ONLINE 0 0 17 (repairing) gpt/WD-WX21D947N1RP ONLINE 0 0 12 (repairing) gpt/WD-WX21D94216X7 ONLINE 0 0 20 (repairing) raidz3-2 ONLINE 0 0 0 gpt/WD-WX41D948YAHP ONLINE 0 0 25 (repairing) gpt/WD-WX21D947N06F ONLINE 0 0 18 (repairing) gpt/WD-WX21D947N3T1 ONLINE 0 0 21 (repairing) gpt/WD-WX41D94RNT7D ONLINE 0 0 5 (repairing) gpt/WD-WX41D948Y9VV ONLINE 0 0 18 (repairing) gpt/WD-WX41D94RNS62 ONLINE 0 0 24 (repairing) gpt/WD-WX21D9421ZP9 ONLINE 0 0 28 (repairing) logs mirror-3 ONLINE 0 0 0 gpt/zil0 ONLINE 0 0 0 gpt/zil1 ONLINE 0 0 0 cache gpt/cache0 ONLINE 0 0 0 gpt/cache1 ONLINE 0 0 0 errors: No known data errors This is really driving me crazy since smartmon tools do not display any errors on the drives. Any suggestions are most welcomed!!! Thank you for your time, -- George Kontostanos ---
