    ZFS filesystem support

    in Completed

    Posted

    +2

     

    Running ZFS on OpenMediaVault and it's fantastic.  Shame OMV's base OS is a little long in the tooth (Debian Wheezy). 

     

    I also see FreeNAS is moving to version 10 with a total re-write, and moving to a sort of "AppCafe" system using iocage.  It's in early alpha - I've had a quick play and it looks very, very nice for a home media server.  The system requirements are harsh, though - 8GB RAM minimum.

    Obviously garycase doesn't like Corsair PSUs.

     

    I, on the other hand think they're great.

     

    I have:

     

    CX450 - 24/7 use in my mother's PC, just under 4 years.

    CS450M - 24/7 use in my server

    CX750 - 24/7 for 3 years at 90% load running a number of bitcoin miners

    RM750 - 4/7 for about a year in my severely overclocked gaming rig.  It rarely spins it's fan, and it gets a hammering from the 4.5GHz i5, and two GTX780s.

     

    I've had zero issues with any of them, and the modular PSUs all use the same cables, so I've no fuss figuring out which cables belong to which PSU.

     

    Then again, I also really like Corsair RAM, my AIO water cooler is Corsair, and I have a few Corsair cases.

    I still prefer the 7200 RPM PMR drives if the price is the same or very close. Toshiba appears the only game in town with these specs - at about the same price as 5T SMRs.

     

     

    HGST are still selling 5TB 7200rpm Deskstar NAS drives.  Possibly 6TB as well?  WD have a 6TB Enterprise drive now as well (AE maybe, I don't remember?)

    Do you use spin up groups?

    in Unraid Polls

    As others have said, I voted no, because I didn't realise it would solve the issue I have with Plex pausing at change of media when the new media is on a spun down drive.  The spinup groups would solve this issue and improve WAF.

    and get rid of all spin up and spin down buttons. It is useless.

     

    Might be to you, but I use them quite a bit.  So, not useless.  ::)

     

    Perhaps you can explain how you are using them, it would be beneficial to have an understanding.

     

    Spin down if I know I'm finished using the shares, so the drives don't have to run needlessly for 30 mins or more.  Spin up to save time when shutting the server down, or if I'm going to be using Plex, so there's no delay when starting a movie or show.

     

    I basically have Dashboard open all the time, and preempt the server spinning up or down the drives.

     

    Spinup groups?  Don't use them now, but I can see merit in them, so I say keep them.

    Temp warnings on SSD cache

    in General Support

    Posted

    OK, so my cache drive runs pretty warm, because it's rammed up against the CPU heatsink. It's running around 40C normally, but when Plex is transcoding it'll head well up past 55C.  It's well within it's operating temp (0-70C), but UnRAID's temp warning keeps going off.  I want the temp warning for the HDDs to be around 50C, but the SSD to be 65C.

     

    So, how do I change the warning temp for one particular drive?  Or is this not supported?

    Not supported at this time

     

    My subtle way of requesting it to be supported.  ;)

    I am debating trying the Nidec/Scythe Gentle Typhoons. 

     

    All the vital cooling in my house is running with Gentle Typhoons.  My gaming rig's H100i has a pair of 120mm Gentle Typhoons (the 1250rpm version), and my server's main cooling is a 1500rpm Gentle Typhoon.  The air flow from those things is immense, and they don't need any rubber mounting or such-like as they run so smooth.  I like seeing a fan take 15-20 secs to stop spinning from ~1000rpm after powered off.  Big heavy motor and beautifully made bearings.

    First unRAID build (H87I-PLUS / Lian Li PC-Q25)

    After having this running now for over a year I think it is time I try unRAID v6.

     

    So I got myself a second USB and a second KEY, now the question is, is the hardware actually good enough for unRAID v6?

     

    Currently it only runs a few PhAzE plugins (Plex, Trasnmission, Filebot)

    These should just run again in V6.

    But if I want to take advantage of Dockers or VMs, will my hardware support that?

    And if not, what would I have to invest in?

     

     

    Absolutely it's more than good enough for v6.  Only thing I'd be wanting to do is a bigger cache device, but even that is likely to be unnecessary.

     

    Definitely move to Dockers, they really are the way forward.  Even MS is working with Docker for Windows 10, so Dockers are going to become very, very popular which is nothing but a good thing.

    Downsizing my unRAID -- e-ATX to mini-ITX

    It's a huge shame the Q25 is more or less end of line.  They're nearly impossible to get now in EU, and they're expensive if they are in stock.

     

    I've had two of them in the past, and sold them both.  I still sort of regret that.

     

    In fact, my old unRAID 5 box was in a PC-Q25B with an Asus P8-H61I Plus and a Pentium G620.  It was a solid little machine.

    CPU freq not stepping down

    Here's something interesting. 

     

    Test system: MSI B85M-Eco with i3-4350. 

     

    Idles at 3600MHz on 4 'cores'.  38W at the wall with all drives spinning.

     

    Turn off Hyperthreading, now idles at 2100MHz on 2 'cores'.  Still 38W at the wall which to me says with HT on it was idling OK, but just reporting wrongly.

     

     

    So without HT, it seems to report frequency OK.  With HT it doesn't.  :o

     

    Interesting.  Is that the normal range for that proc (2100 - 3600)?  The haswells we have scale from 800MHz to 3.x GHz (the x varies based on the exact model proc).

     

    No, it normally idles at ~800MHz running Windows.  But, disabling HT means it's not (possibly) running at 3600MHz all the time.

    jonp: so I thought Xen should be showing me the right cpu speed. That is xl top. It is showing full freq speed. My config is in my sig.

     

    So how sure are we this is only a haswell issue?

     

    Might be a Xen issue.  I know on Windows if you're running Hyper-V, Task Manager only shows the top speed of the chip, even though it is still throttling (as shown by CPU-Z or similar).  Maybe Xen does the same to linux?
