 Posted: Thu Oct 29, 2015 7:08 am Post subject: localmount fails on boot |
 |
|
Hi,
Recently on the rare occasions I need to reboot I've found that localmount fails to start when booting.
The thing I don't understand is that its supposed to attempt to mount file systems based on the contents of /etc/fstab which looks like...
| /etc/fstab: |
# /etc/fstab: static file system information.
#
# noatime turns off atimes for increased performance (atimes normally aren't
# needed); notail increases performance of ReiserFS (at the expense of storage
# efficiency). It's safe to drop the noatime options if you want and to
# switch between notail / tail freely.
#
# The root filesystem should have a pass number of either 0 or 1.
# All other filesystems should have a pass number of 0 or greater than 1.
#
# See the manpage fstab(5) for more information.
#
# <fs> <mountpoint> <type> <opts> <dump/pass>

It fails when trying to mount '/dev/disk/by-label/backup250gb' reporting that there is no such device but it shouldn't even be trying to mount it since its got 'noauto' flag against its entry in /etc/fstab so no attempt to auto-mount it should occur. I have to comment all of my USB/Backup devices out if I want a clean boot.
My inital thought was that it might be udev not having started, but thats in runlevel sysinit and starts before localmount which is in default...

Any ideas on why this is happening and how to correct it would be very much appreciated.
Thanks,

You may add some sort of delay, so the disc is able to spin up. It exists for grub2, so I assume there exists something for fstab too. Or some workaround.
One of the usb drives i sold recently needed two minutes to get up. it filled up my dmesg wiht lots of junk messages. The main reason why i dumped it, after not using it for years.
And you may check if you can mount it by hand: '/dev/disk/by-label/backup250gb'
Sometimes the mount point just does not exists or the drive does just not exists. |

Sometimes computers are kinda pedantic. Try "noauto" instead of "noatuo" in that certain line. |

Damn it my mind must be going, as thats the second typo I've made and not noticed myself in the last month. It can't be my eye-sight (I had it tested recently and it was better than 20/20 at around 6/3).
I'll correct that and try rebooting this evening when I get home.
The slightly strange thing is that I haven't edited /etc/fstab recently, I wrote all the USB/Backup section well over a year ago when I did a fresh install on a new SSD and its never complained until the last month.
Anyway, mark another one up against the user being the problem again.
Thanks and I'll remember to read carefully each time (although its quite likely that my mind is reading it correctly so I don't notice).

Sometimes such kind of typing errors get more evident with a more table-like formatting. |
