This is what it's all about: I've got a Linux network with an actual hardware server running two separate virtual machines and a QNAP NAS T-459 Pro+ as a fileserver. Since updating the QNAP firmware on the NAS, the main server cannot access the ISCSI drives anymore.
Effect: All net drives at the workstations are not accessible anymore, so you can't access any file from there.
The hardware server is running XenServer as a virtualisation software, providing one VM as a VPN gateway and another VM as a Samba server (192.168.1.33).
Whenever I try mounting the ISCSI drives on the Samba server using the UUID (as in /etc/fstab), I get:
server01:/home# mount 2d3e150d-a259-4a82-bfe5-f60c6785bc06 /mnt/nfs/backup -t ext3 mount: special device 2d3e150d-a259-4a82-bfe5-f60c6785bc06 does not exist
Though it is possible to access the QNAP-NAS (192.168.1.34) from the Samba server via ssh. I've mounted a NAS-folder on the Samba server using NFS.
Attached I will send you the last entries in /etc/logs/kmsg.
Have you got any ideas? I'm quite desperate, the only thing I could think of is switching the whole ISCSI connections to NFS, though I don't know if that brings any other trouble. What do you think? And could you help me switching it (or solving the problem in another way), as my knowledge end when it comes to NFS and ISCSI? That'd be great!
