Hi guys,
My boot device is currently a two USB stick mirror pool and last week I got a critical warning on the GUI telling me that one device had suffered an irreparable error. I did a zpool status on the shell and sure enough, one of the USB sticks was reporting checksum errors (and that was the affected pool).
I searched the forums and everything seemed to point to a hardware failure, so I replaced the disk.
The checksum error count was very small (13) and today I tried to read and write fully (used dd to read the stick to /dev/null and to write /dev/zero) to the usb stick without any issues. Furthermore, this is a fairly new stick which I bought for this purpose, it's a Sandisk Ultra, around a month and a half old.
Can anyone tell me what do the checksum errors mean? Should I have waited to see if the error counter incremented over the next few weeks/days?
Thank you
