Unable to mount / in read - write mode

[Popof Popof]

The kernel used is a GENERIC one from 6.0.

/ is mounted but in read-only mode and I can use it in single user mode.
The mount command has been created on October 26 2008 and I hadn't start my
laptop since one year so I'm sure that this comes from my update.

Using mount command manually failed:

> mount: /dev/ad0s2a


My fstab file contains

/dev/ad0s2a   /   ufs   rw   1   1
>

but ad0s2a is in ro mode as show mount output

/dev/ados2a on / (ufs, local, read-only)
