ZenPack can find non-existent drives #8

Closed sempervictus closed 2 years ago

Not sure what to make of this one: image

All of the detected drives are correct, all of the 0 one have no equivalent in the system.

sempervictus commented 2 years ago

Interesting, happens with DAS systems too, with many more false positives (i think they're echoes of real devices somehow): image

My initial thought is that those are things like a /dev/bus/0 RAID controller where some indexed drives are behind.

If you look in the details for all those 0 components, can you confirm that the Device Path is the same/similar?

Hoping this just how issue #4 is manifesting.

sempervictus commented 2 years ago

I have almost no RAID hardware in my targets, pretty much all HBAs here. :-\

Unfortunately removing the errant entries doesnt fly - they come back.

daviswr commented 2 years ago

Pull the latest, remodel, and see if anything's better.

Your smartctl examples have been really helpful since I don't have any SCSI/SAS gear around. Also, a friend has sent me a bunch of output from his various servers with SAS and NVMe that I'll be looking over.

sempervictus commented 2 years ago

Confirm, the 0 devices seem to stay down now. Cleaning up as i go, will watch for their return.

daviswr commented 2 years ago

Good to hear, I'll keep an eye out for an update.

megaraid devices now coming up in LUN mode on a host - excellent. BTW, the SMART status and health columns are empty all over.

daviswr commented 2 years ago

Hm, I would've thought status & health test indicators would've been fixed after e5f8bf305034d8e1c8d28808fe6a3c0dc45cf6de or ced07e346fb85123bbde0e600f660b767fd74e20 . Are the indicators gray?

Could you post smartctl --info --health --quietmode=noserial from a device whose status and health columns are empty?

This has been working for a few revisions now - closing as "fixed"
