I'm working on a RH 7.3 with some issues on the partitions so It doesn't boot properly and goes in emergency mode. I booted the machine from an RH 7.3 iso and I need to extract an sosreport in Rescue mode but I have the following errors:

chroot /mnt/sysimage
chroot: failed to run command '/bin/sh': No such file or directory

So I use the following command as in the page https://access.redhat.com/solutions/43133:

ln -s bash /mnt/sysimage/bin/sh

but I'm getting the error message:

ln: failed to create symbolic link /mnt/sysimage/bin/sh: No such file or directory

Could you help me please?

  • symlinking to a file outside the chroot will not and can not work. the linked file is inaccessible inside the chroot, and the symlink is followed with the chroot dir as /. copy the file instead, e.g. cp -a /bin/bash /mnt/sysimage/bin/. Note that a symlink like ln -s /bin/bash /mnt/sysimage/bin/sh will now work because there is now a /bin/bash inside the chroot

  • BTW, the chroot will also need its own copy of any shared libs required by bash. and lots of other stuff if you want to do anything useful inside the chroot.

  • I can't copy because the directory bin in /mnt/sysimage/ doesn't exist

  • that's what mkdir is for. mkdir then cp. BTW that explains your "No such file or directory" error message - you can't create a symlink in a non-existent directory, either.

The link is not public. But most likely you have to use the full path to the bash shell (or be in the folder /bin). Try:

ln -s /bin/bash /mnt/sysimage/bin/sh
  • I already tried that command but It goes in error because the directory /mnt/sysimage/ is empty.

  • So, you solved the problem? Oct 21, 2019 at 15:51
  • unfortunatelly not. I can't proceed because that directory is empty.

  • You might want to update the question with the current status. Commands you tried, error messages,... Oct 21, 2019 at 15:55
  • The command ln -s /bin/bash /mnt/sysimage/bin/sh shows the error message: ln: failed to create symbolic link /mnt/sysimage/bin/sh: No such file or directory. I have the directory /mnt/sysimage/ empty. This is the current status.
