As the others have said:
- Start running periodic SMART Long tests. I recommend a daily Short test and a weekly Long test.
- The drive data actually looks fine. You have several Multi-Zone errors however that alone is usually not reason to replace a drive.
- The next time you have a drive warning, before you reboot your machine, run the same smarctl command and write down the serial number of the drive. You want to do this because the drive name “sde” can change during a reboot.
These names are assigned on a first recognized gets the first letter. Drive 1 may be ready sooner than Drive 2 one time and the next reboot Drive 2 may be ready before Drive 1. Examine the data and see if ID’s 1, 5, 7, 195, 196, 197, 198, 199, and 200 have changed. ID 200 is the only one with a non-zero value right now.
@dan I completely agree with you and I’ve been seeing it a lot over the past few months. People assuming a ZFS error must be a drive failure, when they are two different things. Sure, a drive failure can cause a ZFS error however it is premature to state that without looking at all the data to support that outcome.
