    Re: Thecus n5200 - Files / Folders / Transfer / AD Issues

    Hi,

    I have a N5200PRO firmware 2.00.00. Is it safe to install 2.00.01 without loosing the
    data on the disks ? I have major problems with my N5200PRO, it throws disks out of the
    RAID5 a couple of times each week, says the disk is N/A. After rebooting it is back again,
    but I have to rebuild the RAID5 each time. Not sure if a firmware will fix it, though.

    My system is running 24x7, mostly under full load.
    I read somewhere that the directiry/file names for N5200 cannot be over 256 characters.
    Does this aplly for the N5200PRO with firmware 2.00.00 as well ?

    Rgds,
    KJell

    Dear Sir,

    The firmware update wouldn't damaged the HDD data, but you system seem instable about the HDD show N/A in sometimes, thus would recommend contact with your reseller for checking.

    KJell,

    what hard disks are you using?

    Hi Kjell,

    also the following would probably help:
    - check the fan speed - under full load it should be around 2500rpm (full speed)
    - check the SMART-data of your drives - you may use omega's INFO-module, but it doesn't give all the info that'd be necessary, otherwise you could install SYSUSER, SSH and connect to your drive, then issue "smartctl -d marvell -A /dev/sd?" - replace "?" by "a" thru "e" and look out for weird values.

    My suspicions:
    - drives get too hot (they turn off when reaching certain temperatures like 75°C)
    - drives are no good (SMART status will have pending or reallocated sectors)
    - drives are unsupported by the controller (see compatibility list)
    Hardware mods:
    # they void your warranty
    # they may seem to work, but kill your machine later on
    # they are mostly unneeded, because the engineers who built a machine knew what they were doing...

    Well, those are supposed to be compatible. We sell N5200 with those drives...

    No problems so far, unless the drives have gone down...

    Kjell,

    I'd be inclined to agree with Stefan that it could be your disks are overheating and shutting down, especially as you say that "My system is running 24x7, mostly under full load."

    If possible run the smartctl command that Stefan showed and this should show a current and max value of the drives temperatures.

    I had this issue on one of my boxes the other day, I had the case off and the drives got rather hot and one stopped... which is all it takes for the array to degrade and require rebuilding.

    I think the ventilation and cooling on the N5200 could be greatly improved...

    Thanks a lot, I will install the SSHD and SYSUSR asap. At the moment, it's rebuilding the RAID and there is no Module option under System. Is that normal ?

    Yes, that's normal. The module dialog is only available when a RAID is available.

    Re: Thecus n5200 - Files / Folders / Transfer / AD Issues

    I installed SSHD and SYSUSR modules and was able to run the smartctl command. The maximum
    temperature for the two disks that sometimes goes N/A, were 48 and 49 degrees. As far as I know,
    the max temperature for these disks should be 60 degrees, so I guess I can rule the temperature out.
    I also ran Seatool on the disks, and no errors showed up. I suspect that there is something wrong with the N5200PRO box itself, maybe the connections in the slots, or something.

    I did not only suspect a temperature-problem ... could you paste the smartctl-output to this forum? Maybe I can find something (I do that for a living...)

    Re: Thecus n5200 - Files / Folders / Transfer / AD Issues

    Hi Stefan,

    Here is the output of two of the disks, first the one that causes most problem. Seems like the
    Raw_Read_Error_Rate is pretty bad. The next disk has also caused a couple of rebuilds, but seems to be ok for the last couple of weeks.

    Thanks,
    Kjell

    Re: Thecus n5200 - Files / Folders / Transfer / AD Issues

    Are all disks exactly the same model?
    The disk 1 has 901 hours and disk 2 769 hours. Why?
    Despite the fact that Seagate shows all recoverable errors as Raw_Read_Error_Rate I really wonder why both disk are showing so different values for this variable: 91298664 <-> 0

    In my opinion the hard drives are not showing bad SMART values.

    Re: Thecus n5200 - Files / Folders / Transfer / AD Issues

    Yes, they're the same model. One of the original disks had a real fault and I switched it out, that's why the hours are different for the two disks.
    The "bad" disk works for a couple of days, then is "N/A". I logged in on N5200 and saw that
    TRAY2 was not listed in /tmpfs/tmp, wonder if there is something wrong with the system itself. I will
    try to put in a new disk for the one that looks suspicious and see if it improve things. Its recovering right now, can I just take out the "bad" disk and replace it while the system is recovering ?

    Thanks a lot!

    This is my Samsung SP2504C inside my main computer. You see: no RAW_READ_ERROR_RATE and in comparison a very low HARDWARE_ECC_RECOVERED.

    What I dislike most: the SEEK_ERROR_RATE - this might cause timeouts from the drive and by that cause a dropout... I'd try to get the drives replaced. Reason: poor performance/poor quality/too many Errors in SMARTlog.

    You could actually read the error-log via "smartctl /dev/sdX -d marvell -l error" - if there are errors logged, you got a real reason.

    Re: Thecus n5200 - Files / Folders / Transfer / AD Issues

    The big problem here is that several companies have a diffrent interpretation for some of the SMART values. Esoecially the Raw_Read_Error_Rate and SEEK_ERROR_RATE are values for which it is not defined if they should included recovered errors too or not. Unlike almost every other company Seagate counts recoverable errors too and therefore giving you values that high.

    But I still don't understand why the Raw_Read_Error_Rate is so different between the two devices.

    Stefan is right: check the SMART error log or even start a SMART scan on the drives manually using
    smartctl -d marvell -t short /dev/sdX
    or
    smartctl -d marvell -t long /dev/sdX
