[Solved] /home: waiting for /dev/disk/by-uuid

Re: [Solved] /home: waiting for /dev/disk/by-uuid

I remember that there was a lot of talk about seeing boot logs and reading them from file. I also remember that they were going to remove it for security. Anyway - In just wanted be sure my log is fine.

Every time I boot I see fast flashing printout

One or more modules listed in fstab cannot yet be mounted

It is very fast I can't read all. Usually there is UUID of /home and something else - possibly another UUID.

Some other time

... contain errors ...
writing into 
/tmp
Waiting for 
NULL

I haven't seen much of this print out... unfortunately.


Sometimes it will login system correctly - just slowly. Sometimes I log in, system is numb I need to restart.

It's always switching brightness few times during different stages of boot and starts system with highest. Than I need to decrease it. Doing so on keyboard by my Laptop Function Key throws up a scale with 0% on it and it's flashing few times, even that brightness is already down. In other cases - changing brightness will hang system for few minutes or for good and restart is needed.

Re: /home: waiting for /dev/disk/by-uuid

I have a similar problem -- can you help?
Machine (ThinkpadT500; Kubuntu 9.10 64bit) wouldn't boot out of hibernation, so i had to hit the power switch.
On reboot I get:

One or more of the mounts listed in /etc/fstab cannot yet be mounted 
/: waiting for /dev/disk/by-uuid/4cb8e22e-71ce-407e-badb-489690128c5f
/tmp: waiting for (null)

And it just sits there for ages...
I've dropped to a shell and fsck'ed the disk with -raf to force fixes. It says it's clean, but reboot always brings back to the same place.

fstab looks like this:

# <file system> <mount point>  <type> <options>    <dump> <pass>
proc      /proc      proc  defaults    0    0
# / was on /dev/sda1 during installation
UUID=4cb8e22e-71ce-407e-badb-489690128c5f /        jfs  errors=remount-ro 0    1
# swap was on /dev/sda5 during installation

/dev/scd0    /media/cdrom0  udf,iso9660 user,noauto,exec,utf8 0    0

Any ideas?

Notice, it's jfs. I'm thinking that was maybe a bad choice fs...maybe it's time for backup reinstall in ext4?

Re: [Solved] /home: waiting for /dev/disk/by-uuid

I have a bunch of jfs partitions, and run my sidux root filesystem on jfs. It is a native 64-bit filesystem, so it is most efficient on a 64-bit OS. I doubt that's the problem. However, you might try some different boot options. Here is my sidux root filesystem:

UUID=0def4abe-79be-45b8-84e7-e963cdc65e0f / jfs defaults,noatime 0 1

and here is a storage filesystem:

UUID=2b7ce29a-4550-4c6f-9171-8406d9688da7 /media/DOCSBAK jfs auto,users,rw,exec,noatime 0 2


I think your "errors=remount-ro" option is probably not appropriate for jfs. (research needed to confirm)

Yes, that's why I installed it -- I figured it would be good for a 64bit OS.
The "errors=remount-ro" thing was added by the installer. To experiment, I've changed it to the same as yours and will report back.

Re: [Solved] /home: waiting for /dev/disk/by-uuid


- Is my problem same as his ?
If it isn't - than devnulljp you should start a new topic because both of us ill not get anywhere.

I wonder also about hat causes it ?
Can it be wrong association of /home partition to newly installed system ?

Those look fine. What says

cat /etc/fstab

?

It's on reply nymber 13 in this topic.

Looks very similar to Fintan's fstab

Re: [Solved] /home: waiting for /dev/disk/by-uuid

I don't see anything truly "wrong" with it. I use more than just the "defaults" option on it -- here is an ext3 partition on my system:

UUID=e4a45430-1c4a-4432-91db-265cfe7dd645 /media/123WORK ext3 auto,users,rw,exec,noatime 0 2

One question that comes to mind -- is your swap working? Just type "top" in the Konsole and look at the status information in the fourth line at the top of the output.

Also, it would be interesting to see what the output of

sudo mount

is.

Re: [Solved] /home: waiting for /dev/disk/by-uuid

That looks fine.

As far as I can tell, you have a perfectly functioning system.

OK, a "perfectly functioning system with an odd boot message".

:P

Re: [Solved] /home: waiting for /dev/disk/by-uuid

I cleaned my 9.04 and I left some file on /home partition. Most of hidden ones were removed to not get old options for KDE4. On first start I had big problem to start Kubuntu. I left /home like it was and reinstalled system on / partition. Now it works better. I wonder if formating system and reinstalling it again will help ?
On other hand, if other people have the same problem than I assume it's something with Karmic. Maybe doesn't work well on some computers.
- Shall we look into Hardware than ?

Re: [Solved] /home: waiting for /dev/disk/by-uuid

Not to throw a 'me too' on the pile, but I have had intermittent errors like this as well, and in case it aids in the sleuthing, i've included my info as well. For me, it hasn't seemed to harm the system after booting, and the induced delay was minimal, but the scary-sounding errors were there. I assumed it was something to do with the new booting, which appears parallelized and inconsistent (i get a different sequence of messages every time i boot -- so far, it boots every time and no big problems, but it's always interesting to see what crops up...) I also get pretty different behavior if i'm booting on battery or wall power (Dell Inspiron 6000 laptop).

Anyway, if it helps:

This is 9.10, upgraded from 9.04, on a dual-boot with XP.

I don't know if this implicates a swap problem:

Swap: 2104504k total, 0k used, 2104504k free, 319044k cached

No. Just means that swap isn't being used. I have a 2G swap partition, and it never gets used.
