Proxmox's FreeBSD istgt information is outdated

[aragon]

Hi,

The wiki page at:

http://pve.proxmox.com/wiki/Storage:_ZFS

Contains outdated information regarding FreeBSD's iSCSI target implementation (istgt). Specifically it has reload support that was fixed a few years ago AFAIK.

So reloading configuration is a matter of:

service istgt reload

Example log entries of two reloads:

Apr  2 15:47:38 <daemon.notice> cstor1 istgt[29722]: reload configuration #1
Apr  2 15:47:38 <daemon.notice> cstor1 istgt[29722]: delete LU1: Name=iqn.2005-10.com.zapop:cstor1:empty
Apr  2 15:48:11 <daemon.notice> cstor1 istgt[29722]: reload configuration #2
Apr  2 15:48:11 <daemon.notice> cstor1 istgt[29722]: add LU1: Name=iqn.2005-10.com.zapop:cstor1:empty

I'm wondering now how to make Proxmox's storage API take advantage of these facts?


Thanks,
Aragon

If LU has active connections, then reload (SIGHUP) does not work:

Jun  1 12:53:45 storage istgt[91704]: reload configuration #1
Jun  1 12:53:45 storage istgt[91704]: istgt_lu.c:2375:istgt_lu_reload_update: ***ERROR*** update active LU1: Name=iqn.2012-06.ru.chics.oc.storage:target0, # of TSIH=9

I would use the native FreeBSD 10 ISCSI (excellent performance unlike istgt), but there is a problem:

That problem is a show stopper to me!

The problem is solved in 10.1-RC2:

excellent performance, easy to use...

Can be proxmox developers will support native iSCSI target for FreeBSD?

when FreeBSD 10.1 is released and Proxmox has libiscsi-1.12 I will look into it. It will require writing a new helper module for the new native iSCSI implementation in FBSD 10.
