Re: New error on CIFS mount "CIFS VFS: ioctl error in smb2_get_dfs_refer rc=-2"

I finally got a chance to re-try this with an older Raspbian version: 2018-06-27. I see the same error there.

The change (if there is any) must therefore have been triggered by an update on the Synology SMB server, not on Raspbian.
The Synology is on kernel version 3.10.105, by the way.

Yes, this must be the reason for the messages. If you add ˋvers=3.0ˋ after the user credentials, you can get rid of the first warning message.

Re: New error on CIFS mount "CIFS VFS: ioctl error in smb2_get_dfs_refer rc=-2"

Got this same message without any external share... That's pretty much impossible ;) Maybe nothing is mounted via fstab, but there must be a 'mount' somewhere else, going to an SMB share. The first one is a warning which does not affect anything. It's just telling you that a share is mounted with S...

Re: New error on CIFS mount "CIFS VFS: ioctl error in smb2_get_dfs_refer rc=-2"

Reads like systems are catching up with the SMB v1 bug I think this is going on for a while now. A friend of mine had troubles about a year ago with his Volumio player along with a cheap NAS. When the Volumio made >v1 mandatory, it could no longer access the shares. My Synology requires v2 or more ...

New error on CIFS mount "CIFS VFS: ioctl error in smb2_get_dfs_refer rc=-2"

Since one of the latest updates (probably kernel 4.14.79) I get a warning or error when a CIFS share is mounted: CIFS VFS: ioctl error in smb2_get_dfs_refer rc=-2 The share seems to work anyway on first sight, but I haven't done any extensive tests. The same update generates a warning if the SMB ver...

While that is a useful feature it's not the whole story.

Re: No bootcode.bin only USB boot on new 3B+ ?

Could somebody refresh my memory on what the point of "bootcode.bin only" is? It's to debug boot problems. One can attach a UART to USB cable to the Pi, and then you see the very early boot messages from the boot loader. The built-in boot loader does not do this, unfortunately. Once everything is d...

There is another OTP bit that can be used to increase the USB wait time from 2 seconds to 5 seconds. That's very helpful, thanks! I knew that this option exists when using bootcode.bin, but I had no idea that this can also be enabled without an SD card. The issue with bootcode.bin / Rpi3+ is appare...

Re: STICKY: USB boot now working on Pi3

I usually need 2-3 tries (unplug/replug the power to the Raspberry Pi) before the Raspberry Pi 3 Plus boots from an external SSD. Direct reboot almost never works, I again have to unplug/replug one or more times. During a reboot the USB Disk remains powered, so it's not a question of startup time af...

Re: Headless WLAN with Stretch, how?

From what I have read in other threads, this does not work anymore. But I have not tested this myself: I fixed the wpa_supplicant.conf file before I fixed the SD card itself, so by the time the Pi could boot, the rest of the headless configuration was already ok.

Everything is fine now. The image boots, and the wpa_supplicant.conf works with this content:

Code: Select all

country=CH
ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1

network={

Thank you both! I'll give it a try. So far I don't have the "ctrl_interface=/var/run/wpa_supplicant" in my file.

Raspbian March Edition doesn't fit to compute module?

The CM3 with on board flash can't host the March edition of Raspbian: The image is quite a bit larger than 4GB. The ZIP file is around 1.6GB, but inflates to a 4.4GB .img file. Apparently a lot of empty space is part of the image.

Is this a mistake, or can the CM3 really not host Rasbian non-lite?

On the May 10 Raspbian image I ran "sudo apt-get update && sudo apt-get upgrade". A package "raspberrypi-kernel" with a date of "20160512-1" was installed. Yet after a reboot, "uname -a" still shows 4.4.9, May 6.

How can I get the new kernel version activated?
