Re: [Scst-devel] [PATCH] Unify the three SCST init scripts

[Matteo T. <ma...@RM...>]

Bart,

it does not help. I was originally thinking the same thing, but I re-created the config file from scstadmin, modprobing modules, echoing to mgmt sysfs, and writing with -write_config.
I tried even removing target config lines from scst.conf, but i get the same error message. Tried even VDISK_FILEIO uppercase, but nothing...

Really stuck...

i'm trying to use the new fantastic scst init script but it fails: 

[root@nas1 default]# /etc/init.d/scst start 
Loading and configuring SCST [FAILED] 
Collecting current configuration.. 

FATAL: Received the following error: 

groups(): Driver '' is not available 



Config is as simple as possible: 
# Automatically generated by SCST Configurator v2.0.0. 
HANDLER vdisk_fileio { 
DEVICE SDD { 
filename /dev/sdd 
} 
} 
TARGET_DRIVER ib_srpt {

} 
}

} 


And scstadmin config validation works fine: 
[root@nas1 default]# modprobe scst 
[root@nas1 default]# modprobe scst_vdisk 
[root@nas1 default]# modprobe ib_srpt 
[root@nas1 default]# modprobe iscsi_scst 
[root@nas1 default]# scstadmin -check_config /etc/scst.conf 

Collecting current configuration: done. 

-> Checking configuration file '/etc/scst.conf' for errors.

All done. 
[root@nas1 default]# 



Am I missing something obvious? or is the init script having some trouble loading appropriate modules? what should be inside /etc/default/scst for sysfs-mode? 



The error message "groups(): Driver '' is not available" has been generated by scstadmin. Apparently a target driver module that should have been loaded wasn't loaded. I see only one possible cause for this, namely that scst.conf was hand-edited and some other separator had been used than a single space in the "TARGET_DRIVER" lines. scst.conf parsing has been relaxed in r3568 on the trunk. Does that help ? 



P.S. any news on scstadmin ALUA support?? 

Mark maintains scstadmin. I'm not sure how far Mark got with implementing ALUA support in scstadmin. 

Bart.
