multipass [MacOS Big Sur] fatal error: cannot open file, Operation not permitted

Describe the bug Fatal error(Operation not permitted) occurred when I try to build the webrtc-android source code. notice：The source code is on the mounted directory. I tried to modify the file permissions(chmod 777) but it take no effect.

The error log is as follows：

Hey all, we're now looking at alternatives to the mount solution that should improve reliability and performance.

In the mean time I suggest, if possible, to build outside of a mount - there will always be overhead to transfer files between the host and the instance.

Dec 09 '21 16:12 Saviq

Is there any news on this? I have a npm project where I cannot install packages using multipass with the same error. Feels very stuck if a virtual environment cannot install npm packages..

Apr 17 '22 22:04 OlegGulevskyy

Unfortunately the problem still exists after 2 years. Mounting drives from the (Mac) host to the VM is pointless as the compiler constantly encounters “operation not permitted” errors. Relying on mounted directories makes the multipass environment virtually unusable...

How can we support the multipass developers with the problem?

Nov 16 '23 10:11 guenterberner

Hi @guenterberner, everyone,

Sorry this hasn't been given more attention.

Best guess

This could have multiple causes, but the first thing I would advise is to check the limit for open files in macOS (see #1933):

launchctl limit maxfiles

I believe the default is 256, which is pretty low for buildind things. If that is your case, could you try to increase this limit and let us know if it helps?

sudo launchctl limit maxfiles 10240

You may need to disable System Integrity Protection. You may also need a few more steps to make the change permanent (?).

Other things to consider:

What are the read permissions for all relevant files? You could try to see if running chmod -R o+r <folder> on the host makes any difference.
Does the build need to write into the mount and, if so, are the relevant directories writable? (again, does chmod -R o+w <folder> help.)
are there any symlinks to files that are outside of the mount?

Further input

Finally, if none of the above helps, there are a couple of ways you could help us gain a better understanding into what is going on:

a simple recipe to reproduce
changing the verbosity of the Multipass daemon to trace (see below) and posting the logs when the problem occurs (messages with "sftp server" are of particular interest).

Here's how you can increase the verbosity:

stop the multipass daemon with sudo launchctl unload /Library/LaunchDaemons/com.canonical.multipassd.plist
edit /Library/LaunchDaemons/com.canonical.multipassd.plist and change verbosity from "debug" to "trace"
after saving the file, restart the multipass daemon: sudo launchctl load /Library/LaunchDaemons/com.canonical.multipassd.plist

Nov 16 '23 12:11 ricab

Also, a possible workaround to try is to use native mounts if you're using classic, or vice versa:

multipass umount ...
multipass mount -t native ...
# or
multipass mount -t classic ...

Nov 16 '23 13:11 ricab

@ricab

I finally found some time for further testing.

I ran "sudo launchctl limit maxfiles 20000" on the Mac and shared a source directory with the commands:

multipass mount -t native /Users/<USER>/dev primary:/home/ubuntu/macdevN
multipass mount -t classic /Users/<USER>/dev primary:/home/ubuntu/macdevC

In the multipass shells I entered "sudo ulimit -n 15000". This is more than enough. On a native linux, we can comple the project with ulimit -n value of 1024.

Within macdevN (and macdevC) within the Multipass VM, I compiled a CMake/C++ project consisting of 742 .cpp files. The build occurs entirely in the mounted directory.

Observations on native mount: Within macdevN, compiling the project failed after creating ~150 *.o files with "Too man open files".

Observations on the classic mount: In macdevC, compiling the project failed after creating ~460 *.o files with "operation not allowed".

The numbers of the *.o files created are just a house number for you. The actual file I/O is much higher because all include files and temporary files are involved.

Still I can duplicate the entire source trees in both mounted directories. So accessing individual files doesn't seem to be a problem.

I will add more data (trace stuff) during the next days...

Dec 04 '23 16:12 guenterberner

After changing the verbosity from debug to trace, I cannot open another Multipass shell. The terminal window is opened and after some seconds disappears.

Macos console shows that multipass.gui has crashed. Looks like an exception is not caught and the terminate handler is called.

By the way, switching back to "debug" doesn't change the behavior - I can no longer open a shell at all.

You may find the following detail helpful: When the command "multipass info --all" is executed, the error message "info failed: ssh connection failed: 'Timeout connecting to 192.168.64.3" appears.

Dec 12 '23 08:12 guenterberner

Hi @guenterberner,

Hmm, something odd sure is going on. What does multipass list show? Also, issuing multipass shell <instance_name> in a terminal window doesn't work either? It seems there may be an issue with one (or more) instances. Perhaps providing logs will shed some more light. Thanks!

Dec 12 '23 14:12 townsend2010

Hello @townsend2010,

here we go...

I stopped the multipass daemon, removed the multipassd.log, set the log level to "trace" and started the multipass daemon again.

Here's the requested output:

guenterberner@gbe-mac-mini ~ % multipass list
Name                    State             IPv4             Image
primary                 Running           192.168.64.3     Ubuntu 22.04 LTS
guenterberner@gbe-mac-mini ~ % multipass shell primary
start failed: The following errors occurred:
primary: timed out waiting for response

I stopped the multipass daemon and here's the multipassd.log

multipassd.log

(ping-ing 192.168.64.3 times out, btw. Is there a way to find out, why the network is unresponsive?)

Dec 14 '23 10:12 guenterberner

Hi @guenterberner!

Looking at the logs, it looks like the instance itself is behaving correctly. I'm wondering if Apple's virtual networking is messing up and has duplicate entries for this instance in its table. Let's please try this:

Stop the multipass daemon.
$ sudo rm /var/db/dhcp_leases
Start the multipass daemon.

Let's see how that goes and then go from there if it's still not working. Thanks!

Dec 14 '23 13:12 townsend2010

Now it gets even worse. After removing the /var/db/dhcp_leases file and restarting the daemon, multipass list remains in state starting

Name                    State             IPv4             Image
primary                 Starting          --               Ubuntu 22.04 LTS

and multipass shell primary

guenterberner@gbe-mac-mini ~ % multipass shell primary
shell failed: Cannot open dhcpd_leases file: No such file or directory

And after a while the multipass list also shows

guenterberner@gbe-mac-mini ~ % multipass list
list failed: Cannot open dhcpd_leases file: No such file or directory

The multipassd.log does not show any warnings or errors

Dec 14 '23 16:12 guenterberner

Ugh, macOS sometimes just amazes me...you may have to reboot your Mac to try to get macOS to realize this change.

Dec 14 '23 16:12 townsend2010

I'm an old Windows user - of course I restarted the Mac ;-)

Dec 14 '23 16:12 guenterberner

I'm an old Windows user

lol, right :slightly_smiling_face:

Ugh..do you the firewall enabled? Also, does creating a new instance work?

Dec 14 '23 16:12 townsend2010

Mac firewall is turned off and I did not change firewall settings inside the Ubuntu/VM.

Creating a new instance works.

guenterberner@gbe-mac-mini ~ % multipass launch 22.04
Launched: blissful-jaybird
guenterberner@gbe-mac-mini ~ % multipass shell blissful-jaybird
Welcome to Ubuntu 22.04.3 LTS (GNU/Linux 5.15.0-91-generic aarch64)
...

The new instance has a fully functional network (both directions)

Is it possible to access the filesystem of the "damaged" instance?

Dec 14 '23 17:12 guenterberner

Ok, then yeah, something bad has happened to the primary instance. :frowning_face:

As far a trying to access the virtual disk, then I would maybe suggest using qcow2-fuse. I haven't tried using that myself, but hopefully it will work for your purposes. The path to where the primary instance's image is located: /var/root/Library/Application Support/multipassd/qemu/vault/instances/primary/ubuntu-22.04-server-cloudimg-arm64.img
