LVM Issues

[jan1024188]

Ok,

After almost getting killed by LVM's second time this year today (near heart attack) I'm never using them again (from F18 on).

So I have 2 SSDs:
128gb with Fedora 17 - volume group vg_janpc00
64gb with Fedora 16 - volume group vg_janpc

So when I was installing F17 I had F16 ssd on. Now today I decided to cleanup my 64gb drive (created new partition table) and after rebooting I get this:
http://shrani.si/f/P/5V/MPBoxFN/2012-06-13-010427.jpg

So I reinstalled fedora on 64gb ssd that recreated vg_janpc and lv_swap respectively, however Id like to be able to boot and use F17 without dependence of my other SSD.

How can I achieve this? I believe swap, root and home are all on 128gb ssd.

[jan@janpc ~]$ ls /dev/vg_janpc/
lv_home lv_root lv_swap
[jan@janpc ~]$ ls /dev/vg_janpc00/
lv_home lv_root lv_swap

Also bootloader is on 128gb one. The whole LVM is luks encrypted.

Do you always scare this easily?

As far as I can tell this has nothing to do with LVMs.

Linux is often trying to use all available swap space and now it's just complaining because one of them has disappeared. Try

cat /proc/swaps

or check your /etc/fstab for swap entries.

[jan1024188]

In both instances I happend to have my work without backup. Thats why I scare. Now Ill setup another encrypted drive and have automatic daily backups on it.

[jan@janpc ~]$ sudo cat /proc/swaps

/dev/mapper/vg_janpc-lv_swap swap swap defaults 0 0
/dev/mapper/vg_janpc00-lv_swap swap swap defaults 0 0

So if I remove:
/dev/mapper/vg_janpc-lv_swap swap swap defaults 0 0

Will this solve the issue?

Removing it from fstab didnt fix, please help.

Where is /boot located?

[jan1024188]

It has own ext4 partition on 128gb ssd.

Have you removed the F16 swap entry out out /etc/crypttab of f17?

I dont think its there.

[jan@janpc ~]$ sudo cat /etc/crypttab
luks-a35ca127-7576-492f-9739-3285c2073397 UUID=a35ca127-7576-492f-9739-3285c2073397 none

[jan1024188]

Guys, help me how do I make my F17 not want to use swap on other sdd? HELP!

[sea]

Interesting, your crypttab has just 1 entry.
So i assume, you just have to enter the UUID of the swap partition, in the pattern that is for the root partition already done.

To get the missing uuid, check lsblk or blkid

[george_toolan]

So what exactly did you do?

After you edit /etc/fstab you'll have to reboot or at least swapoff/swapon for the changes to take effect.

Is the swap space still being used?

cat /proc/swaps

cat /etc/fstab

[jan1024188]

Here outputs:

Still cant figure out how to disable swap in vg-janpc so it will let me delete it and boot.

[jan1024188]

Actually I've just noticed its in grub.cfg the requirement for swap I dont want.

How do I remove it and non make it ever appear again?
