De man mount
:
mount -a [-t type] [-O optlist]
(usually given in a bootscript) causes all filesystems mentioned in fstab (of the proper type and/or having or not having the proper options) to be mounted as indicated, except for those whose line contains the noauto keyword.
De systemd.mount
documentação :
noauto, auto
With
noauto
, this mount will not be added as a dependency forlocal-fs.target
. This means that it will not be mounted automatically during boot, unless it is pulled in by some other unit. Optionauto
has the opposite meaning and is the default.
Como você pode ver, qualquer linha /etc/fstab
com noauto
não será montada automaticamente ao usar o comando mount -a
.
Você tem noauto
no seu /etc/fstab
. Se você fosse remover isso, então deveria funcionar.
