How do I delete the /usr/ports when it says device busy

[mrusli]

Hi

Currently I am using FreeBSD 12.2.
I wanted to delete the /usr/ports and download the svnweb subversion.
How do I go about doing that???
Please help.
Thank you.

What is the output of df -h and mount -p commands?

 

[rootbert]

fstat | grep "/usr/ports"

Maybe you have some other session logging in that's in that directory?

Also note, with a ZFS install, /usr/ports is a separate filesystem, which means you can't rm -rf /usr/ports itself, only its contents. You would need to use zfs destroy to actually remove the /usr/ports/ directory itself. Not needed if you just want to checkout a new ports tree. Just remove its contents, not the directory itself.

You would need to use zfs destroy to actually remove the /usr/ports/ directory itself. Not needed if you just want to checkout a new ports tree. Just remove its contents, not the directory itself.

Oh no wonder I cannot use the rm -rf /usr/ports command on my zfs.

So how do i zfs destroy, /usr/ports???

There is no need to destroy the dataset, just run rm -rf /usr/ports/* /usr/ports/.svn as SirDice suggested:

Thank you.

The /usr/ports is a ZFS dataset.

After you do rm -rf /usr/ports command you HAVE a clean /usr/ports directory, but you can not delete that directory because its ZFS dataset. Do delete ZFS dataset you will have to use zfs destroy zroot/usr/ports command, but as you are saying that you want to fetch a fresh copy of Ports then you only need this:

# rm -rf /usr/ports
# portsnap auto

Regards.

$ sudo fstat | grep "/usr/ports"
rusli sh 886 wd /usr/ports 34 drwxr-xr-x 85 r

kill -9 886 to kill that process which accesses /usr/ports, then destroy that zfs dataset as recommended above

 

[SirDice]

That's just a different shell that happens to be in /usr/ports. Even if he exits that shell, he still won't be able to remove /usr/ports itself because it's a separate ZFS filesystem. ZFS isn't going to allow you to remove its mountpoint if the filesystem is mounted.

Just to reiterate, you don't need to remove the directory itself, only its contents. The directory only has to be empty for a subversion checkout to work.
