    That was it, thank you!
    TLS email jobs being default without the necessary libs, revering to regular smtp/25 sorted it out. This being all local net I'll leave it for now. :)

    Hi again :)
    New project, new questions:
    1. HGST Ultrastar He12 12TB HUH721212ALE604 512e or 4Kn ?
    2.They'll be brand new 12 drives , no mixing, provided by Intel's c622@SuperMicro X11SPM-F_-TF_-TPF . Solaris/Solarish - it will be latter decision . No ZoL, very little chance for ZoF.

    I need advice for position #1 and general thoughts about #2 .

    Thanks in advance .
    P.S.
    The main filler's "User" is begging me for single raidz2/3, my plan is 2x6raidZ2 in stripe (60), I'll not surrender :).

    P.S.2
    Large media files :
    40% still image sequences, where the smalest chunks are 30mb minimum,
    60% "1GB+" files.

    512e or 4kn
    Does not matter for ZFS, both are 4k physical and ZFS will use both with ashift=12 (4k mode)

    Dual vdev (ex 2 x 6 Z2) vs one vdev (Z2/3)
    Sequential performance is quite similar, With dual vdev you loose capacity but your pool has twice the iops. Important for small random io (this includes access to metadate) or resilvering time.

    Yep _Gea
    I'm grateful, may be for a double digits in a row. The time to move a step forward has come.
    OFF TOPIC :
    Month ago I made media storage - LSI 9631-8i, RAID 10, SATA multi path, 8 used 4TB HGST HUS724040ALE640, MB Asus x79, Win2012r2 Essent. Emergency build, users satisfied. But I'm not impressed at all with the result. Not to bash LSI off course - best in the class, but lack of setup/setting/tuning options and especially - the inadequately documentation is annoying .

    Will report the final outcome of the present effort- week for the MB's delivery but.

    Regards!

    Do you mean LSI 9361-8i ?
    This is a Raid 5/6 controller, not good for ZFS. Use a pure HBA (LSI 2008, 9207 or 3008 chipsets), best with IT mode firmware, IR firmware is ok - nothing else.
