This no longer mounts when the machine boots (it used to).
/dev/sdb1 /storage ext4 noatime 0 2

sudo mount -a

does NOT work.

Code: Select all

sudo mount /storage

DOES work.

What is the error message when mount fails?

Try to add the auto option.

Code: Select all

/dev/sdb1 /storage ext4 noatime,auto 0 2

There is no error on the console or in dmesg.

I'll try it the way you wrote it.
I tried it before with no space after the comma and I may have put it before the noatime.

The thread title says "mount failure". If mount failed, it should produce an error message. If there is no error message, then we need more details about what is not working. You said that sudo mount -a does not mount the volume. Does that mean that, even after the system is fully booted and all modules are loaded, the volume still does not mount via mount -a? When in the situation that mount -a does not mount the volume, what is the output of file -s /dev/sdb1 ; nl /proc/mounts; mount -a -v?

/storage is not automounting on boot (and mount -a won't do it).
I think it is a failure even though there is no error message.

# file -s /dev/sdb1 ; nl /proc/mounts; mount -a -v

nothing was mounted

I'll run an fsck /dev/sdb1
[/code]

You provided the output of mount -a -v after it was already mounted. I would like to see the output when it is not yet mounted.

Adding the explicit

Code: Select all

auto

fixed it for now.
If it is intermittent, I will post again.
Thanks everyone.
