SMART Results for Lifetime

[godman91]

Hello all,

I am rather new to the FreeNAS system. I have had this running for only a few days of time and I was able to learn a bunch about ZFS, SMART, ARC, L2ARC, etc.. However, I am still learning. I have attached a screenshot of the results of short SMART self-tests. Can someone let me know what the lifetime(in hours) represents for the drive. I think it is referring to the lifespan left of the HDD but I would like to confirm.

Check out the link in my signature for SMART Results.

EDIT: Actually that may not answer your specific question. The specific values you indicated are the power on hour time the test was completed or failed.

Say, you don't have SMART Short tests scheduled to be conducted every hour, do you? Change that to once a day and the Long tests to once a week. These are my personal preferences, others have different opinions.

Okay, thank you joeschmuck for answering my question. I am glad to know the lifetime does not represent life expectancy of the drive. I do not have any schedule created at this time; however, I will go off of your personal preferences.

Also, just to add, I don't run the FreeNAS all day. I turn it on every now and again when I want to do some work with my ESXi lab environment (the Freenas acts as the ISCSI datastore for the hosts).

You would probably be happier with something other than FreeNAS/ZFS, then...

Thanks for the input Ericloewe, what would you suggest I use?

I dunno, but ZFS requires monstrous amounts of resources to present applications with block devices, so you'd want something based on a simpler filesystem, possibly with hardware RAID.
