FreeNAS Boot SMART testing?

[Darren Myers]

I had to look into the SMART results of all my drives, and one of my boot devices came up with pending sectors...yet i never got an email about it, so after looking into my short and long SMART testing, it only allows me to select daX (x being 0-20)...So no option to check the SMART status of ada0 and ada1 ....soooo whats up with that?

I just check from the GUI and my boot drive ada0 is on the top of the list in:
Tasks > S.M.A.R.T Tests > Add S.M.A.R.T Test

Maybe it has something to do with your hardware and how the SSDs are connected???

 

[Darren Myers]

SSDs are direct connected to motherboard, they were there at one point I'll double check when I get back in front of it

I noticed your post in the bug thread... You don't suppose this could be related, do you?

 

[Darren Myers]

Very well possible, but I don't think I'm sharp enough to determine it lol, I only update once a month or so.

 

[Darren Myers]

I don't even have an option to select ada0 or ada1. But it was there before I updated I didn't think to check before

 

[BigDave]

So no option to check the SMART status of ada0 and ada1

My server now has mirrored 16GB DOMs. I'm now wondering why MY machine is only showing ada0 under setting up smart tests??

 

[Darren Myers]

mhmmm maybe something is fouled up somewhere, i cant see either ada0 or ada1 under SMART testing, OR the view disks.....something is really wrong.

 

[rogerh]

As a matter of interest I am on the latest stable 9.3 and my boot SSDs, which are ada4 and ada5, don't show up in the "add smart test" menu or in existing smart test schedules. I thought there was a bug about this and it was largely dismissed with something to the effect that USB sticks don't benefit from smart tests. Do DOMs have SMART?

Thats kinda stupid not to SMART SSD's.....or DOMs

 

[BigDave]

Do DOMs have SMART?

Yes, both my DOMs are smart capable and reports (from smarctl -a /dev/adaX) are basically the same as any other SSD (at least the ones I've looked at).
I just ordered two used Intel X25e 32GB SSD (8860 FW) and will be installing 9.3 on them and fiddeling around with some different configurations.
I have only six drives hooked to my HBA, so I have two spare data cables to utilize for the mirrored boot drives, leaving my Mobo's SATA ports empty.
Can u tell I'm bored?

Many disks do NOT support SMART testing.

Not supported... easy answer. Why didn't anyone figure this out? :p

Many SSDs, DOMs, and USB thumbdrives have no SMART testing supported.

Thats ok cyber, i appreciate the feedback, and it does give me some insight to what happened now.

 

[cyberjock]

For the SSDs that do support SMART tests, are the tests useful in predicting failure? Or even detecting failure? If so, the option to test them would be useful.

To be honest, I haven't heard of it being too useful at all. SMART really was designed for mechanical drives. So I tend to think that SMART tests are probably useless. Monitoring definitely isn't useless as it warns of excessive number of writes on the cells and other problems. I have no doubt that there is probably someone, somewhere that has benefitted, but I'm fairly confident it's not nearly as useful as it is for mechanical drives.

 

[Ericloewe]

I'd argue that the failure mechanisms of NAND flash are far easier to keep tabs on during normal operation than through some sort of dedicated test. It could be useful to order a refresh of somewhat degraded cells, though.

It's perhaps an ignorant question, but how do you "keep tabs" on them in normal operation, say as an OS drive? Sorry if this is a bit off-topic.

SMART monitoring, of course. It's just the SMART tests that are of doubtful usefulness.

 

[rogerh]

SMART monitoring, of course. It's just the SMART tests that are of doubtful usefulness.

Which brings us back to the OP (almost); is SMART monitoring applied to the boot disks, if they are SMART capable? There is no way in the GUI to set or unset this. Edit: or add extra options, I meant to say.
