Topic: hddtemp, raid 5 (4 disks), sme 7.1u3

[bhamail]

I'm setting up a new server (v7.1 update 3) and I can't get hddtemp to work with my drives.

Code: [Select]

# hddtemp /dev/sda1
/dev/sda1: ATA WDC WD4000YR-01P: S.M.A.R.T. not available

What's odd is that I originally installed SME with just one of these drives, and hddtemp worked fine. (There was no "not available" in the output).

Does hddtemp work with drives in a raid configuration?

Thanks,
Dan

There is an incompatibility between hddtemp and kernels newer than 2.6.19-rc5-mm2:

http://bugzilla.kernel.org/show_bug.cgi?id=7581

The fix requires patching and rebuilding the kernel.  I don't know if I'd want to try this with SME Server. You might want to try an alternative program like smartctl instead:

Hi MJB,

Thanks for the reply. I don't think my stock kernel is new enough for this to explain the problem:

Code: [Select]


# uname -r
2.6.9-55.ELsmp


Any other thoughts? By the way, smartctl is able to read the hdd temp:

Code: [Select]


# smartctl -d ata -a /dev/sda

Ideally, I'd like to use hddtemp, if only to have the hdd temp readings show up nicely in smeadmin.

Any other suggestions?

Thanks,

Just found some more info: Forcing the [type] in the hddtemp command seems to help matters:

Code: [Select]

# hddtemp SATA:/dev/sda
/dev/sda: Success

A little odd that SATA doesn't show more, since these are SATA drives. Odder still:

Code: [Select]

# hddtemp PATA:/dev/sda
WARNING: Drive /dev/sda doesn't appear in the database of supported drives
WARNING: But using a common value, it reports something.
WARNING: Note that the temperature shown could be wrong.
WARNING: See --help, --debug and --drivebase options.
WARNING: And don't forget you can add your drive to hddtemp.db
/dev/sda: unknown:  33�C or �F

Does it make sense that forcing PATA should work?
Next question maybe should be directed at sme7admin: What's the best way to force the type in the sme7admin config for hddtemp?

Thanks again,
Dan
