Help activating Swap partition
When I was laying out my hard drive for a dual boot with Windows 7 64 bit, I created a swap partition and I just realized I have to activate t first.
I tried following this guide and I got kind of lost.
I got to the step 3 without a problem. Here's the info the terminal yielded.

nick@PUTER:~$ gksu gedit /etc/fstab &

The text editor brought me this:
Quote:
# /etc/fstab: static file system information.
#
# Use 'blkid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).
#
# <file system> <mount point> <type> <options> <dump> <pass>
# / was on /dev/sda6 during installation
UUID=9dcaf243-3947-46db-9b16-33c781759ee6 / ext4 errors=remount-ro 0 1
/dev/sda7 none swap sw 0 0
A bit lost to say the least now
Re: Help activating Swap partition
9173; Hi !
Not a problem, all that is required is to edit that file and add the entry for the swap partition.
Need to get the UUID so we know what to add:
And carry on from there.
ain't nothing but a thing

Re: Help activating Swap partition
When I run I get the UUID and stuff for all the other partitions, but all that is listed for the Swap is
Quote:
/dev/sda8: TYPE="swap"
No UUID or any other info.
After I get the UUID I add it into the document? But where in the document do I paste it? Probably a dumb question, but it isn't obvious for me. Re-uploaded document for easier viewing

In case it isn't obvious, I've only had Ubuntu for about a week now. Loving it so far though
Re: Help activating Swap partition
9173, well !
Should be something like this:
Code:
/dev/sda5: UUID="192a4783-56fa-4fd0-a62f-c45a14c08482" TYPE="swap
we will find that UUID, so we are sure of what we are doing post the out put of terminal code:
And welcome to the club, it is a steep learning curve, but I assure you, well worth the effort !
Kinda busy right now, but I will

Re: Help activating Swap partition
9173; Sit down, take deep breath;
Format is presently HPFS, that is proprietary to Windows, Linux (ubuntu) will not touch it.
There are no good ways around it except to reformat the drive(s) to some other. Now If there is valuable data, and there is no way to back up that data, I am aware that there is a risky way to convert the dynamic partitioning back to basic, But never been there never done it and I understand it is risky ( as in any partitioning operations).
Best bet is to reformat the drive(s) and re-install Windows in say GPT format. Then ubuntu can cope with it,
We did not make the situation
we just got to work with it
Re: Help activating Swap partition
One more bit of code to check the UUID on /dev/sda8 OP.
Code:
sudo tune2fs -l /dev/sda8 | grep UUID
If that gives an output, I'd recommend edit /etc/fstab (gksu gedit /etc/fstab) and use uuid= in fstab like has been done for the root partition but for swap, removing the /dev/sda8 (see edit below sda7 is the wrong partition for fstab and swap in your case) bit. UUIDs are a far more flexible means of mounting.
Once the uuid is added to the /etc/fstab file use,
the swap partition will now be mounted.
To use as swap,
Code:
sudo swapon /dev/sda8
If you can't find the UUID on /dev/sda8, ie no output above you will need to set one
Code:
sudo tune2fs -U random /dev/sda8
This will actually set a new UUID to the partition. Find what it is for use in /etc/fstab from the first tune2fs command above.
Good luck.
@ Bashing-om, /dev/sda8 shows as linux swap / solaris in that attachement not windows, check again please. Cheers.
Edit: your /etc/fstab points to /dev/sda7 the swap partition is /dev/sda8, first retry editting /etc/fstab to sda8 . Might be an easy fix, but UUIDs would be better imo. cheers

Re: Help activating Swap partition
@ coldcritter64; appreciate watching my back.
I did catch that the swap partition was made, however - and I may be jumping at conclusions, that maybe ubuntu is to be installed onto another drive - but, There is no provision on the sda drive for ubuntu. As the drive is HPFS, there is no way. The current fstab references sda6 as "/", that partition is also Windows proprietary HPFS partitioned, not ext4 (or other linux schemes).
Am I missing something here, or do I have a failure to comprehend ?

OP, what is on /dev/sda6 & /dev/sda7 (anything data wise ?) your gparted shows /dev/sda6 as unknown but terminal shows it as HPFS etc as Bashing-om notes, also /dev/sda7 on your gparted output shows as ext4 but once again the terminal shows HPFS (???) How did you install the system in such circumstances; was wubi involved in any way OP ?; ubuntu on a NTFS filesystem ?; (it is not the same as "bare metal" dual booting) and may be important to know if it is used here.
@ Bashing-om, I think this is a bit deeper than I first noted :). fdisk isn't noting a GPT table so sda6 sda7 and sda8 are logical partitions and as such Windows can't boot from there (the OS itself, ok for storage though). Unless they are storage volumes it seems they are being detected wrong either in terminal or gparted (they differ for the same device) or may be wrongly formatted. Interesting :-k.
Re: Help activating Swap partition
@ coldcritter64; Yeah !
My thoughts too.
I have been in contact with the OP, and have asked the OP the meet us in the thread to clarify what he is doing and what his intentions are.
Gonna hold off for additional info.

/dev/sda6 Encrypted Partition created with truecrypt
/dev/sda7 Just Ubuntu.
Wubi was not involved in anyway.
As for installation, I laid everything out with Minitool Partition Wizard (probably the issue?) and then just installed Ubuntu on the ext4 partition from a DVD.
Re: Help activating Swap partition
9173; Nope, I can't see it !
All partitions less swap are HPFS + NTFS or fat .. UHMMM.. ubuntu default install is onto a partition of file type ext4. The installer will happily find "unallocated space" and format it to ext4, but not otherwise.
Now I know nothing about encryption and such, but I do know that on a hard disk, ubuntu will not install on a windows format, and in particular will not touch the proprietary partitioning scheme HPFS.
In my very limited Windows knowledge, the only thing I see to do is back up the data, and (RE-)install Windows using a different BASIC partitioning scheme. Set up then the "unallocated space" ? or let the installer work it's magic and make the install. Then ubuntu can cope.
Re: Help activating Swap partition
I'll just leave it as is if it just means no swap.
What other problems (if any) would just leaving it as is cause?
Re: Help activating Swap partition
9173; ???
We are working with conflicting information.
To this time it is "unproven" that there is an ubuntu install on that 1st hard drive (sda).
Now there is a /swap partition, and if there does exist an ubuntu install on sda, it is a minor thing to edit /etc/fstab file so the operating system picks it up.
Show us the outputs - between code tags to maintain readability - of terminal codes:
Code:
sudo fdisk -lu
sudo parted -l
sudo parted /dev/sda unit s print
lsblk -f

To remove all doubt and so we know what we are working with.
One may do with out a swap under these conditions:
The system will not be hibernated;
and
there is 8 gigs or more ram installed;
and
There is no heavy duty computing going on- intense calculations.

Re: Help activating Swap partition
9173; Hey ...
Looking good, now we KNOW !
Ok what is currently .
ubuntu IS installed to the 1st hard drive (sda) in partition #9 (sad9);
ubuntu's swap partition is installed to that 1st hard drive as partition #11 (sda11);
Sidenote - file id 7 we can deal with !
so you want to boot with 'swap' automounted at boot.
Let's get the updated info:
Code:
sudo blkid
cat /etc/fstab
and I will provide you the edits to the /etc/fstab file to make it happen.
