Other Autofs -media mount efi partition.

A

airwan

Hello,

I would like to use autofs(5) to mount removable disk. I followed the HandBook Automounting Removable media section. However, this mount a device
/dev/ada1p1 which seems to be an efi partition :
$ ls /media/ada1p1/
efi

and
$ /etc/autofs/special_media ada1p1
-fstype=msdosfs,nosuid,async :/dev/ada1p1


I am not happy with this, because there is no reason to clutter /media with this. I read the devd.conf(5) maybe to block some special file but I did not succeed.
 
This sounds very much like the linked thread below. Why not try to mount ada1p2?:

Solved - XFCE shows less storage space in External Hard Drive

Hi Recently bought 5 TB Seagate External Hard Drive, Xfce shows less than 5 TB storage space. See Screenshot below: Following two icons appear when hard drive is connected to Workstation. Left one gives error trying to mount, whereas right one is mounted. Also, when trying to copy files...

Thanks, I read it but it does not answered my question. The reason I would not have this partition mounted is because I do not understand why it is available to be mounted! I know autofs will mount everything he can. Let see below my configuration : I have essentially 2 disks, ada0 and ada1

I use ZFS and mirrored my filesystem so that partition 4 (zfs) is :

Code: 
$ zpool status
  pool: zroot
 state: ONLINE
config:

    NAME        STATE     READ WRITE CKSUM
    zroot       ONLINE       0     0     0
      mirror-0  ONLINE       0     0     0
        ada0p4  ONLINE       0     0     0
        ada1p4  ONLINE       0     0     0

We see that partition 3 (swap) are mounted:

Code: 
 $ cat /etc/fstab 
# Device        Mountpoint    FStype    Options        Dump    Pass#
/dev/gpt/efiboot0        /boot/efi    msdosfs    rw        2    2
/dev/ada0p3        none    swap    sw        0    0
/dev/ada1p3        none    swap    sw        0    0

As well as efiboot0 which is ada0p1 (i do not known a command to confirm that). See also :

I do not know where are gtp partitions (ada0p2 and ada1p2) but what I understand is that efiboot1 (ada1p1) is a "mirror" of efiboot0 (ada0p0). So why it is available to be mounted, or how to avoid this ? because I do not want to have twice the same partition to be mounted. Thanks for your help.
 
I've had trouble with automount all yesterday trying to dump my ext4 backups to my zpool. I'm about to install Linux and just sftp everything over. It's so annoying when geom complains about my disks even when in Sata in the box.
