Hello all
First off, I am running Oracle Linux 7.6 on a Hyper-V 2016 VM for a
customer. I know this is not an Oracle Linux mailling list, but because
Oracle Linux and CentOS are so similar, to an extent, I figured why not ask
on here because someone MIGHT know the answer.. Here is the issue. I have
a 600MB /boot partition allocated on a UEFI system. The /boot/efi partition
is on a separate EFI partition. Recently, I noticed that this system has
been crashing every few minutes and when I checked the disk space, I
noticed that the /boot partition has zero free space available. I removed
all of the old kernels and left the running kernel in place, in hopes that
will free up some space. It freed up about 50MB or so, but then the system
would crash again. After I would reboot the VM to bring the system back up,
I ran a df -h /boot, and the results were reporting ZERO disk space again
for the /boot partition.. It makes absolutely no sense how a partition
which is generally static UNLESS you move something into it, is running out
of space after space has been manually freed up in the partition! What
boggles me even more is that when I do an ls -lh /boot, the file systems do
not add up to 600M (well 594M) at all. See below:
df -h

I have no idea what is going on here and why the space keeps filling up and
the VM crashing! ANY and all help will be greatly appreciated! Thanks!
I am running the following kernel:
4.14.35-1844.0.7.el7uek.x86_64
Thanks!
