The only ways I am aware of
on shutdown
Both of these work independently of fstab. I believe when you try the fstab method you are seeing standard behavior.
I am having a problem with fsck. I am new to UNIX but was placed in a position where I must learn it. Anyway, one of the instructions that I have been given is to use 'fsck -f -y' when I am having trouble with the filesystem. The problem is that I am getting an error message that says the -f...

I consulted with a fellow sysadmin, and he suggested running "fsck -N" on the filesystem in question without unmounting it. So I... (1 Reply)

Hi,
I need to fsck the root file system on my Solaris 9 server. It is a UFS file system but it is under Veritas control. I want to know which fsck I need to use to check the file system. The default Solaris fsck (/usr/sbin/fsck) or the Veritas (/lib/fs/vxfs/sparcv9/fsck) fsck? I take it I... (3 Replies)

If i run fsck on one filesystem and fsck need to repair some things then this partition must be unmounted

Hi,

As I know in /etc/filesystems these parameter should be there just like in Linux /etc/fstab
I have created file system aix test but unable to find the option of... (1 Reply)

dracut-shutdown.service
DRACUT-SHUTDOWN.S(8) dracut DRACUT-SHUTDOWN.S(8)NAME
dracut-shutdown.service - unpack the initramfs to /run/initramfs
SYNOPSIS
dracut-shutdown.service
DESCRIPTION
This service unpacks the initramfs image to /run/initramfs. systemd pivots into /run/initramfs at shutdown, so the root filesytem can be
safely unmounted.
The following steps are executed during a shutdown:
o systemd switches to the shutdown.target
o systemd starts /lib/systemd/system/shutdown.target.wants/dracut-shutdown.service
o dracut-shutdown.service executes /usr/lib/dracut/dracut-initramfs-restore which unpacks the initramfs to /run/initramfs
o systemd finishes shutdown.target
o systemd kills all processes
o systemd tries to unmount everything and mounts the remaining read-only
o systemd checks, if there is a /run/initramfs/shutdown executable
o if yes, it does a pivot_root to /run/initramfs and executes ./shutdown. The old root is then mounted on /oldroot.
/usr/lib/dracut/modules.d/99shutdown/shutdown.sh is the shutdown executable.
o shutdown will try to umount every /oldroot mount and calls the various shutdown hooks from the dracut modules
This ensures, that all devices are disassembled and unmounted cleanly.
To debug the shutdown process, you can get a shell in the shutdown procedure by injecting "rd.break=pre-shutdown rd.shell" or
"rd.break=shutdown rd.shell".
# mkdir -p /run/initramfs/etc/cmdline.d
# echo "rd.break=pre-shutdown rd.shell" > /run/initramfs/etc/cmdline.d/debug.conf
# touch /run/initramfs/.need_shutdown
