Hard Drive not mounted on reboot

pplucky · 17. März 2015

Hello.

I have recently noticed that one of the 2 Hard Drives connected via USB to my Raspberry PI 2 running OMV 1.14, simply doesn't mount by itself.

I already had my SD card system partition full due to the drive not being mounted while running an rsync backup, so I needed to write down a bash script to make sure all connected hard drives are properly mounted before actually starting the rsync backup.

Still then, considering that the hard drive is declared properly in /etc/fstab and that it mounts properly if I run 'mount -a' via CLI, why doesn't it mount automatically when I reboot my system?

Any ideas?

Thanks in advance and best regards.

Still happens, so I would appreciate any ideas on why this may happen. Thanks in advance

In fstab are you mounting the USB drives by device names or are you using UUIDs?

Initial mount was done via OMV Gui, so using UUID.

There is probably some type of race condition and the problematic USB drive is taking longer to appear to the system and it isn't seen by the time the filesystems are mounted.

Maybe a boot delay would help by editing /etc/default/grub to contain:

GRUB_CMDLINE_LINUX_DEFAULT="quiet rootdelay=10"

Then

sudo update-grub

This file doesn't exist in my installation... Maybe I'm missing something.

I have it in mine - OMV v2.1.17 (Stone burner). Look again?

OMV 1.19 (Kralizec)

I think grub came along later than 1.19.

pplucky · 12. Oktober 2015

I will do the upgrade to Stone Burner later anyway. I will let you know.

pplucky · 12. Oktober 2015

No such file, on openmediavault 2.1.17...

Maybe some plugin needed missing?

I dunno, I have it on mine.

Don't think the rpi uses grub, doesn't the rpi use a proprietary closed source boot loader ?

@ryecoaaron should know better. I would look at dmesg for errors on mount, just after boot.

RPi uses u-boot (it is open source - driver blob on RPi is closed source). The problem is that the config.txt file in /boot/ uses drive letters (/dev/sdX) to find the boot drive. It isn't very consistent about keeping the same letters. So, it will try to pick the non-boot drive sometimes. I couldn't get uuid to work reliably in that file but it has been a while.

Jetzt mitmachen!
