Yesterday, i had my drive pool configured as a set of mirrored drives.
While copying some large files and i looked at the console to see errors. Did a zpool status and found 175 write errors on my da1 drive.
Today i reformatted disks a raidz3 pool. After doing a zpool status, i dont see any write errors. But when i look in dmesg.today i see messages like this:
(da1:mps0:0:9:0): CAM status: CCB request completed with an error
(da1:mps0:0:9:0): Retrying command
(da1:mps0:0:9:0): WRITE(10). CDB: 2a 00 00 40 75 b8 00 00 20 00
(da1:mps0:0:9:0): CAM status: SCSI Status Error
So i enabled the scrub to run. I wait a few hours. I do a zpool status and see this:
pool: pool
state: ONLINE
scan: scrub repaired 0 in 0h0m with 0 errors on Wed Oct 4 20:49:34 2017
config:
So now i'm really confused.
1) I no longer see write errors now that zfs is reconfigured as raidz3.
2) I expected to see more write errors now that im scrubbing the drives every hour, but i dont.
Yesterday i thought i should return the da1 drive to Amazon. But now i cant get the evidence i need to do it. Whats up??
