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?

Once I've deleted all rescue kernel images from my system, I need to regenerate/recreate these images. The only information I've found was about Fedora (here ), so it didn't help me.

I'm switching to Dracut and I've numerous problems. In order to eliminate them one by one, first I want my system to boot correctly. So my Grub2 entry looks like this: menuentry 'dracut' { load_video insmod gzio if [ x$grub_platform = xxen ]; then insmod xzio; insmod lzopio; fi insmod part_msdos insmod ext2 set root='hd1,msdos1' if [ x$feature_platform_search_hint = xy ]; then search --no-floppy --fs-uuid --set=root --hint-bios=hd1,msdos1 --hint-efi=hd1,msdos1 --hint-baremetal=ahci1,msdos1 829c0201-9b6d-4e18-8464-9d2551311ea6 else search --no-floppy --fs-uuid --set=root 829c0201-9b6d-4e18-8464-9d2551311ea6 fi echo 'Loading Linux 4.9.0-2-amd64 ...' linux /vmlinuz-4.9.0-2-amd64 rd.shell rd.debug log_buf_len=1M echo 'Loading dracut initial ramdisk ...' initrd /initramfs-4.9.0-2-amd64.img } I expect to be dropped into the rescue shell and then manually assemble the root file system, and continue booting; but there is no cryptsetup binary in the rescue shell. Dracut configuration file /etc/dracut.conf.d/* looks like this: do_prelink=no add_dracutmodule+="cryptsetup" Relevant list of modules are as follows: # dracut --list-modules | grep crypt dracut: Executing: /usr/bin/dracut --list-modules crypt crypt-gpg crypt-loop ecryptfs How can I add cryptsetup so I could manually unlock the encrypted partition manually (via rescue shell)?

I had a problem booting my computer, so I ran a Live cd and booted it into rescue mode, started SSH and went back home, then I fixed the boot error remotely, and now I want to restart my server so that I can boot my system, but when I try to run any of the following commands I get an error saying : root@debian:~# reboot Running in chroot, ignoring request. root@debian:~# shutdown -r 0 Running in chroot, ignoring request. So, my question is : **Is it possible for me to restart my server from inside the chroot?**

We have a problem on a centos 6 server. normally, PasswordAuthentication is off. When I get connected using rescue mode, I execute these commands : mount -o remount,rw / chroot / /bin/bash passwd root It says password reset successfully. And I also try to edit /etc/ssh/sshd_config and /etc/ssh/ssh_config to enable password authentication, but the problem is that none of the modifications is saved after reboot. And when I try the new password with ssh, it does not work. Do you have any idea?

I have a CentOS 7-Minimal VM running on a Windows 7 host that has been happily running for a year or so. A kernel panic occurred and I was unable to boot into anything except the rescue kernel. While trying to troubleshoot the panic, I removed (via yum remove) all the other installed kernels and was going to simply reinstall the latest. However, for some reason I cannot mount any ISO file (CentOS, VBox GuestAdditions, etc) to install the kernel package. Attempting to mount an ISO doesn't recognize the file system: The drive is attached: I hope I am missing something simple, but I've spent half a day trying to get this working to no avail.

I have a Centos 7 server that won't boot, it's giving me the following errors I can boot to single user mode but I just get the following when I try to query any of these services with systemctl `systemctl status polkit Unit polkit.service could not be found.` Any ideas what could be causing the boot issues or what the best way to troubleshoot this is?
