    Other iSER module not present.

    I am trying to use the iser module as detailed in the man page's alternative method to building the kernel. https://man.openbsd.org/FreeBSD-11.1/iser.4 I've checked both FreeBSD 11/12 and I cannot locate the module. Is there really a iSER module for FreeBSD?

    Other FreeBSD iSCSI iSER Target

    I dug around for an hour but what I found so far is that iSER is only supported in the initiator. And even for the initiator I need to recompile the kernel because the module seems to not be compiled in the distribution and as far as I read it needs "option OFED" (is it such a performance hit...

    Other Constant "iSCSI Session is restarted" using isboot-kmod

    I have been able to successfully boot FreeBSD 10.4 over iSCSi using net/isboot-kmod. However, once booted I continuously get the following message. iSCSI session is restarted This leaves me with an unstable system as random filesystem accesses will hang on zio->io_cv. Once this happens, the...

Those SSDs are setup in mirrored vdevs and a zvol shared over iSCSI with vmWare which has it formatted...

    Solved Can FreeBSD Serve Tape Drives as iSCSI Targets?

    Some background on my environment and use case: I would like to share my LTO5 tape drive via iSCSI with a server that will be doing backups to tape, but having the tape drive in a more convenient location to switch out tapes. The FreeBSD box is running pfSense and acting as a router (however, I...

    Other iSCSI Multipath

    Hi I was looking for some info about iSCSI, does it support multipath on a FreeBSD? I have found only really old discussions about that, and all were.. unoptimistic. Does somebody have tested it with FreeBSD 10.3 RELEASE? Thanks!

    Other iSCSI Mount Points at Boot

    I am fairly new to FreeBSD having made the switch based on a really good experience breathing new life into an Xserve G4 with FreeBSD 10.2. So, I decided to switch out from CentOS Linux to FreeBSD on my dev server. I was able to get everything up and running with no problem. I followed the...

    What is the state of iSCSI stability & performance today?

    Hello everyone! Have anyone tried the new iSCSI target code that came with FreeBSD 10? Is it working and performing well? I have a plan to run a replicated Microsoft SQL Server on a iSCSI LUN hosted by ZFS over 10GbE, my primary goal is to take a consistent "backup/snapshot" of the database...

    Other iSCSI transfer: 12 TB job, 24 TB down, 10 TB up. How's that work?

    I set up a 16 TB zfs pool (vdevs are all 2x mirrors) to create a "life preserver" array for a colleague who needed iSCSI storage for his 12TB life's work online in a matter of weeks. I see there are different phases to an iSCSI transfer, but I don't see how anything the target would normally...
