Hardware/Dell
Efivars is full
Encountered this issue on A Dell server
Failed to create EFI Boot variable entry: No space left on device.
during bootloader install
Googling DbocBoot
only shows one result https://bbs.archlinux.org/viewtopic.php?id=276175
Running strings
on the DbocBoot
entries show that they contain strings like Windows Boot Manager
and Ubuntu
and other old efi boot entries
bcfg boot dump -v
in EFI shell does not show these variables, only Boot*
variables
The fix is to remove the DbocBoot
entries
Normally the files are protected therefore it is necessary to remove the protection
chattr -i /sys/firmware/efi/efivars/DbocBoot*
Then they can be removed
rm -vi /sys/firmware/efi/efivars/DbocBoot*
During the next boot there may be a warning
Warning: Corrupted BootOrder variable detected... Repaired
and the boot will continue as normal.
