[arch-general] Cannot delete chroot directory

[Simon Doppler]

Hi all,

I wanted to create a new build chroot directory with mkarchroot yesterday, and
mistakenly created it in the wrong place. I then interrupted the process but
after it had already created some files but was not finished. (I wanted to
created in ~/chroot/multlib, but wrote ~/multilib).

When I tried to delete the directory (with rm -rf) but I could only delete all
the files it contained. It did not work either after a reboot.

This is my terminal output when I try to delete the directory

[***@tollana dopsi]# LANG=en rm -rf /home/dopsi/multilib
rm: cannot remove '/home/dopsi/multilib': Operation not permitted
[***@tollana dopsi]# lsattr | grep multilib
------------------- ./multilib

I noticed in [1] (the lock function is defined in [2]) that the directory is
locked using flock, but that lock should not survive a reboot (or am I mistaken
?).

Thanks for your help

Hey hey Simon,
have you looked at the access rights:
ls -ld multilib
Perhaps, by some freak accident, there is no w attribute. It's the only
thing that springs to mind.

HTH and best wishes,

Jeanette

Hi Jeannette,

I just got an off-list anwer from Florian Pritz that mkarchroot does create a
btrfs subvolume (when the chroot would be in btrfs), which is the case for me.

I used

# btrfs subvolume delete <directory>

to delete the directory.

Thanks both for your help

If you run btrfs, this is a btrfs subvolume which you need to remove
with `btrfs subvolume delete`.
