[one-users] iSCSI problems

Tue Apr 29 09:25:11 PDT 2014

I did the following:
at the NAS:
NasKampdreef11> chown 9869:9869 /volume1/@iSCSITrg/
NasKampdreef11> chown 9869:9869 /volume1/@iSCSITrg/iSCSI_1_LUN-1_000
chmod -R 0755 /volume1/@iSCSITrg/

at the frontend:
[root at OpenNebulaServer ~]# chown 9869:9869 /dev/sdc
[root at OpenNebulaServer ~]# chmod -R 0775 /dev/sdc

AND I Forgot
chown 9869:9869 /var/lib/one/datastores/100/

I don't know if I need all of them but now it magically works...
