We are seeing a strange warning on a VA as shown below:
and here is the response from systems guys:
So I did some reading, and this mount point efivarfs cannot be expanded because
it resides in firmware-managed NVRAM, not on the disk. EFI Variable Filesystem
(efivarfs) is a special virtual file system provided by Linux that allows UEFI
firmware variables to be accessed by the operating system.
When a system boots in UEFI mode, the firmware stores settings, such as:
Boot order
Boot entries
Secure boot key
Firmware setting
Vendor specific UEFI variables
Linux makes these available through/sys/firmware/efi/efivars. It's complaining
about the space it is mounted on; efivarfs shows on the left as the mount point.
So the space comes from the motherboard firmware (NVRAM), not on the hard drive,
which is why the size is only a few KB. So this doesn't mean the disk is full;
it simply reflects firmware variable storage and is nothing to worry about. So
we can't resize it because it's not a disk. Looks to be okay since we have 29 KB
available
Here is what is taking up some space in the file system
We could remove any unused entries. We only have 27 variables not hundreds or
thousands so we are good and space is not filling up. We may not need to be
monitoring that Filesystem in PRTG, the main disk to look for is in the / (root)
Has anyone faced a similar issue, and if yes, how did you handle it?
Thanks in advance for any insights
