Ineed to rebuild initramfs on latest Oracle Linux 7 by its rescue disk because I changed volume group name go root folder.
I changed fstab, grub.cfg but I missed to rebuild initramfs so after boot machine doesn't start.
When I run dracut command In rescue mode to rebuild ram disk I get this message :
...
*** Creating image file ***
*** Creating image file done ***
cat: write error: Broken pipe
Can you suggest me how to solve it please?
