vboxsf does not support noatime,nodiratime,discard options

Reported by: RoelV Owned by:

When using a mount (/etc/fstab), for example as follows:

ssd /ssd vboxsf noatime,nodiratime,discard 0 0

And trying to mount, you get:

[roel@localhost /]$ sudo mount -a unknown mount option `noatime'

Removing the options one by one shows it does not support any:

unknown mount option `nodiratime' unknown mount option `discard'

Yet, using 'defaults', i.e.:

ssd /ssd vboxsf defaults 0 0

Works fine.

This is very significant, as it does not allow for mounting a SSD with SSD recommended options (noatime,nodiratime,discard).
