    Looking for help in scsi-target product find and decision

    Hello !

    I am looking for the "right" scsi-target for my Ubuntu 12.04 (precise).
    I am searching for days now and I am finally not able to find a product
    with a reasonable documentation. I probaly even do not know, which
    products are "ready-to-use" know, and probably, I did'nt find all relevant stuff.

    I found "open-scsi", "lio", "scst", "iscsi-target", "iet", "istgt", "tagt" and I am finally completely disoriented ....

    Many of them are not in the 12.04 repos ...

    Best option would be to support VHD files and beeing based on
    kernel-modules ...

    The best I found [well documentes, feature rich, kernel-modules] is - so far I imagine - "scst", but I found no "ready-to-use" package. But
    I got no answer for my question on their mailing list.

    Any help would really be "ultra-great"

    Thanks anyway and
    best regards,

    I recommend this
    http://linux-iscsi.org/index.php/LIO-Target

    It's production ready and targetcli is the easiest to use as far as I am concerned.

    Cheers

    On Precise, all you need to do is, 'apt-get install targetcli' and everything is installed and awaiting your administrative skills.

    Hi !

    Thanks !

    LIO is one possibility, but this one has no options. Even
    "istgt" can host VHDs, but this is not a kernel module.

    What do you mean with 'but this one has no options'?
    Have you looked at this, 'http://linux-iscsi.org/index.php/LIO-Target'?

    Please read the BACKSTORES section carefully. Does VHDs mean 'virtual hard disk'? You can use vdfuse to mount them then.

    Cheers.

    Hi !

    I am currently using "istgt", because it can host my VHDs [yes:virtual hard disk].
    See: http://osdir.com/ml/freebsd-scsi/2012-09/msg00022.html
    This works basically, but is not a kernel imlementation and so probably
    does not give me high performance, like all FUSe related things are
    missing this ...

    Thanks for the page to LIO; Knowed it, but - up to now - havent had the
    time to read that all.

    I was more familar with this:
    http://scst.sourceforge.net/comparison.html

    It is a shame, that there are two projects at work, but not one
    really ready-to-go. What does this tell me about the influence of
    the linux community ?? .... Just irritated ... Both have it's pros
    and cons.

    Will - at next - make a VM with LIO, to see, if it works with
    ZFS on boot.

    Thanks!
