No, I never manually spin down disks. I let the Areca BIOS settings do it.
Results can vary between drive mfgs.... such as many WD drives returning SMART data when spun down and many Seagates needing to be spun up first.
-
I have a script that builds a text lookup table linking the Areca drive #s to Linux /dev/sdX device at boot time since it takes about 5 seconds. Then my other scripts simple use that lookup table so they run very fast.
-
Plus unRAID checks spinstat with hdparm, and you can't use hdparm with Areca controllers.... use smartctl.
-
It's not the HPA that the Areca is flubbing.... you can't run hdparm AT ALL against a drive on an Areca controller... even a drive that is in pure passthru mode.
-
Until unRAID gets a bit smarter about polling drives, and can utilize special syntax for Areca controllers, get used to lots of SG_IO errors in your log.
-
Try a different USB port. And make sure legacy USB is enabled.
You might need to take the HDD, CD, and FDD out of the boot order entirely.
-
Now if we can get drive temps & smart data in the Dynamix WUI this will be a 100% success.
What you have to do it write a couple of scripts as "wrappers" around hdparm and smartctl, rename the original hdparm and smartctl to something else, and apply lots of chewing gum and bailing twine.
Alternatively, the UI could accept as a stored property of each drive, customized commands for pulling smartclt data from that drive.
It would also help if the UI relied solely on smartclt for both smart data and spin status, instead of invoking hdparm for the latter.

Try adding command "udevadm control --reload-rules" before "udevadm trigger"
You can also try changing:
udevadm trigger
to
udevadm trigger --attr-match=subsystem=scsi
-
Just as a test, lengthen it to 30 seconds... if that work, back it down to find what is reasonable and still works.
-
udev hasn't settled yet when you start emhttp. Put in sleep 5 between the trigger and starting emhttpd.
-
Word of caution... the first time you change the udev naming rules, if you already have drives on an Areca controller in an unRAID array, they will not be found and you will need to reassign them. Be sure you have a way to ID each drive and put it back into the correct slot number with its new udev name.

I recall in one of the past betas, I had to tweak the scaling driver parameters because parity checks were going slow due to CPU clock not staying at max.
-
Can anyone else confirm that this is purely a cosmetic issue?
It is. My system actual cpu freqs are at proper idle levels. CPU temp confirm it.

FWIW, you can't run phpvirtualbox in unRAID 6.x even with a web server working, because the php install is incomplete (no extensions, such as SOAP)
-
Btw, can we do LACP in unRAID and bond interfaces in combination with a 802.3ad switch?
Yes... has been there for a long time.

The search function is in the "tasklist"
That only searches summaries...
-
Hmmm... seems to lack a search function?

Not yet. I am at the moment giving up on this. Tested from full Linux install, even Supermicro confirmed that this won't work with the X7SBE, fans are controlled only from the BIOS.
I may connect the fans to an AMX cardframe with 3x VAIG cards (analog voltage out set to 0..12V) and make it login to unRAID and based on smart data and HDD temp, control the voltage on the fans directly. Sounds complicated but this is the best I have come up with. All other fan control solutions I have seen so far can't be controlled from scripts but are autonomous based on some temperature sensors.
There are many hardware solutions out there that allow fan speed control via scripts... check out:

I use the Matrix Orbital, but the T-balancer is a good choice too.

RevoDrives are pretty cheap now. 120gb is about £300 here.
Yup... I've had one for a while in my main desktop and it smokes.
-
Interesting, didn't know that.
No surprise.... it is wrong.
The RIAD-ified SSDs are uber-priced (i.e. Fusion)... the first one under $1000 is the Ocz Revodrive. The fact the 60GB has a bit better performance comes from other efficiencies --- not RAID.

Take a group of three 5.25 slots.
You can have 12) 2.5 drives or 5) 3.5 drives.
with 2TB 3.5 drives, you get 8TB of data and 2TB of parity for $500
with 1TB 2.5 drives you get 11TB of data and 1TB of parity for $1300... plus cost of 7 extra controller ports.
No thank you.

I wish Gigabyte would drop the HPA feature. I love their boards but too afraid of losing data to use one for unRAID.
It defaults to "disabled" in the BIOS now.
I also have this board and like it. Only thing I don't like is the location of some of the headers make them hard to get to with cards installed.

Will this s2ram be of any use to me? Or since my NIC is always getting set to wake on d, am I just SOL?
It is possible... particularly if s2ram has a specific knowledge of your mobo.
Run "s2ram -n" to see if it has your mobo in its database.

Tried any other mfgs other than Hitachi? What about WD greens?
I use --nocheck=standby unless I have flagged the drive a successfully returning SMART data in standby.... particularly when I merely want temperature or spinstat, since temp of a spundown drive isn't going to matter.
