Solved Can't rename /usr/src to /usr/src-old...

ziomario · Jan 4, 2023

Hello.

I'm not able to rename the src directory to src-old. What's the reason ? How can I do this ? (I'm using a FreeBSD 13.1 VM).

Code:

cd /usr
mv src src-old
Operation not supported

Verify it is not mounted &nothing under it.

Or that it's not the current working directory of another virtual console ...

Perhaps you have an aborted build there.
chflags -R 0 foobar

chflags(1)

www.freebsd.org

Try to remove the noschg flag first.

Code:

chflags -R noschg src/

ziomario · Jan 4, 2023

Code:

root@marietto:/home/marietto # chflags -R noschg /usr/src
root@marietto:/home/marietto # mv /usr/src /usr/src-old
mv: rename /usr/src to /usr/src-old: Operation not supported

ziomario,
Please try

Code:

# cd /usr
# ls -la
# ls -la src

... and post the displayed results.

( Edited to add: )

Code:

# df -h

Are you running ZFS with a default setup?
In that case /usr/src is a ZFS dataset, you can't rename that. Been there, done that, scratched my head for a second.

zfs list

I have this:

Code:

root@Silicium ~# zfs list /usr/src
NAME                        USED  AVAIL     REFER  MOUNTPOINT
flash/usr/src.releng.13.1   758M  45.9G      758M  /usr/src

And then
zfs set mountpoint=...

zfs-set(8)

While you can't rename that directory with mv(1) when it's mounted, you can zfs-rename(8) a dataset.

that's nice ! thanks.

what happens now ? what to do ? I've downloaded a new snapshot of the source code and now,instead of the src directory,I see the "src?" directory.

Code:

git clone https://github.com/beckhoff/freebsd-src /usr/src

# ls /usr
bin     include lib32   libexec obj     sbin    src?    tests
home    lib     libdata local   ports   share   src-old

now the "src" directory is called "src?"

Code:

# cd src
src: No such file or directory.
# cd src?
/usr/src^M # ls

solution :

mv /usr/src? /usr/src

Don't know why it appends the character "?"

cd /usr

Looks like you created a directory with a Control-M in the name, somehow, maybe? From what you put above:

Code:

# cd src?
/usr/src^M # ls

So is the ^M really there? That is a carriage return (I think) control character.

Good catch. I looked right past that.

ZFS datasets are not directories.

nope. I've renamed the dataset called "src" with "src-old" using this command :

Code:

zfs rename zroot/usr/src zroot/usr/src-old

at this point,I've created a new directory called src with the command :

Code:

mkdir /usr/src

because inside there I've downloaded the new source code got from the Corvin's Repo,but I've seen that the"final" name hasn't been "src",but "src?". It has been appended the "?" character. Its not me that I've added it.

what it means ? Is it wrong to create a new directory called "src" ?

Solved Can't rename /usr/src to /usr/src-old...
