Re: Converting from iscsitarget to targetcli-fb

[francis picabia <fpicabia@gmail.com>]

Of the packages you mention tgt is the only one which is iscsi target related.

I am looking at targetcli because my situation matches that of this bug report:

https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=865632

That tells me what to migrate to, but the examples for usage of targetcli do not

show working with existing iSCSI set up, only creating new, which would

likely destroy my existing data.

In the bug report it states:

     As the LIO stack was developed independently of the IET, the
     configuration has to be migrated manually.

It doesn't say "you will lose your data", and it doesn't say "here is how

to switch".  I don't understand the inner workings of it.

I guess in a worse case I can try to downgrade to Debian 8 with the older

kernel and use iscsitarget again.

I have an iscsi setup in Debian 9. I don’t think iscsitarget is a supported package anymore? Do you have tgt, open-iscsi, lvm2 installed?

This is with Debian 9 system which had been upgraded from Debian

I have an existing iscsi target blockio device with /dev/md1

Somehow it continued working under Debian 9 until a recent reboot

introduced a kernel update and then the module wasn't found:

FATAL: Module iscsi_trgt not found in directory /lib/modules/4.9.0-7-amd64

The solution in the bug report about that is to switch to targetcli-fb

When I look at the docs for targetcli, I don't see any hints/guides on how to configure

an existing iSCSI target made before on the blockio device.

My google fu has failed to find a guide/hints on existing iSCSI device conversion to targetcli.

Does anyone have a hint or link to share?

I have an existing target with valuable data on /dev/md1 and I need to configure it with targetcli.
