  • I like to propose to use a different tool for benchmarking - called dt.


    It is kind of a dd, but gives you the data directly as an analysis and output.


    You can find it here (very old nowadays) with a linux intel compiled version of it:

    I have written a test procedure somewhere in the RAID section.

    Everything is possible, sometimes it requires Google to find out how.

  • Is it possible to raise a problem for solution on this post? or should I raise a new post?
    The issue is a hard disk that was on my omv before - my parity drive.
    That omv crashed due to the pool vanishing.
    I reinstalled and now I have attached all the disks and everything was OK initially but lately, one hard disk had vanished.
    All my external hard disks are linked via two JBOD via a sata port.
    I have tried to mount it using mount -a but it does not appear.
    I them amended the config.xml file and ran omv-mkconf fstab
    It still does not appear so I found this thread and ran

    Code
    egrep 'ata[0-9]\.|SATA link up' /var/log/dmesg

    and got this output:


    ***see attachment***
    I am sorry but I don't understand what this output is saying apart from the fact that it has issues.
    The missing disk is this:


    What can I do to recover this disk and why can the sata port read three of four disks? I don't understand.
    The only link i found was this and this is 2009. Surely the issue will have been corrected? https://bugzilla.kernel.org/show_bug.cgi?id=13551
    Please help!
