After upgrade to ucs-174 kernel “errata 112,113” server started to show GRUB Error displays: Disk filter writes are not supported in boot
I did a search, and one way to solve this is described below:
To work around this issue, perform the Following steps:
Open the file in an editor /etc/grub.d/10_linux Disable the quick_boot option by setting it to zero: quick_boot = "0" Update the GRUB boot loader: $ Sudo update-grub
The problem is that this file 10_linux is already configured with quick_boot = “0”
Do you have another clue of how to solve this?
