swap problem when booting

[encoreuneffort]

Hello,

I have a problem with my Mandora platform when I boot.

It is a problem with the swap that I cannot solve.

Here is the message I have:
"
... swapon: /dev/Volgroup00-logVol01 : device or ressource busy
"

Thank in advance for any help

That's odd. Try this:

grep swap /etc/fstab

You should see one line. Mine says:

/dev/hda5 swap swap defaults 0 0

If you see some of that Volgroup stuff, then it's coming from /etc/fstab. You might try just editing it to look something like mine (of course you have to have the right partition).

It looks like your swap partition is actually a logical volume, and I don't think that will work. I think swap has to be a regular partition.

Bonjour,

I have to admit that I am far from being a linux expert. I try to read manuals but I really don't have the mind of a programmer ...

I have to say a word about the way I installed Mandriva. Before I had Fedora core 5 installed on my computer, in an extended partition. When I moved to Mandriva 2006, during the partionning step, everything has been done automatically. I think it used fedora's partitions.
I remember I had a volgroup00 with three logical volumes: logvol00 (/ root), logvol01 (swap), logvol02 (/home).

So, I deleted the swap partition that was in the logical volume.
I created a new partition, sda6, in the extended partition where I have Mandriva Linux.
Also I did:
>mkswap /dev/sda6
>swapon /dev/sda6
and I added "/dev/hdxx swap swap sw 0 0" in the file " /etc/fstab".

I don't have anymore problem when I boot.

If I do:
>swapon -s
I have:
>Filename Type Size Used Priority
>/dev/sda6 partition 2048248 0 -1

It seems to be ok ...

I still have a problem when I shutdown:

"
Unmounting file systems:
Shutting down LVM: /dev/dvd : open failed : No medium found
Can't desactivate volume group "VolGroup00" with 1 open logical volume(s) [Failed]
"

Before I made the changes regarding swap, I had something similar with
LogGroup00-LogVol01 (that was the swap).

Any other good idea ?

Thanks

There are 2 problems here.

The reference to /dev/dvd can be sorted by adding a line to /etc/lvm/lvm.conf to tell LVM to ignore unsuitable devices. The line should be something like:

filter = ["r|/dev/dvd|"]

The r means reject (ignore) and it is followed by a regular expression to match the devices to ignore. Make sure such a line is placed BEFORE any line of the form:

filter = ["a/.*/"]

which means accept everything!

The second message about not being able to deactivate the volume group "VolGroup00" makes sense as I think this is your root partition. It can't deactivate that because the shutdown script is running from it! I don't know of a way round that but maybe it doesn't matter.
