file systems will not mount automatically after adding new swap

[mike worrell]

I added my swap by adding a drive to a new volume group, created using SAM a lv called swap, made it swap with pri of 2 and 500 mb

System rebooted , now for some reason it will not mount my file systems automatically. If I do a more on /etc/fstab and mount by hand all is ok. What can I do to fix

there is probably an error in /etc/fstab that is causing the mount at system start to fail.

The error code should be recorded in /etc/rc.log

Take a look at /etc/fstab for a character or tab that does not belong.

mount -a should result in an error after start if I'm right.

Hi Mike,

To expand on Steven's answer...If there's an error in /etc/fstab, all entries *following* that error are not processed.
I'd edit fstab & re-enter that specific line & try a swapon -a

Entry should look *like*:

/dev/vg_name/lv_name ... swap pri=2 0 0


Also I *always* make secondary swap priority=0 so that swap will stay away from vg00 until all the secondary is used - And hopefully swap will never be used as swap or you're in trouble & performance will go to h3ll.

Rgds,
Jeff

Hi Mike,

You could perform the following to check the swap condition:

1. Execute the swapinfo command to see what if your swap device was ever turned on.

swapinfo -mt

2. If the swap was not turned on then, verify it the device information is in the /etc/fstab file.

/dev/vgXX/swap ... pri=# 0 0
Where # is the number you assigned it.

3. Turn swap on using the swapon command

swapon /dev/vgXX/swap

or

swapon -a #This turns on all of your swap devices.

I had problems in the past setting up swap using SAM. If your problems persist remove the swap you created and re-create it on the command line. The steps are.

lvremove /dev/vgXX/swap

lvcreate -L 500 -n lvswap /dev/vgXX

vi /etc/fstab -- add the entry in for the new swap.
/dev/vgXX/lvswap ... pri=# 0 0
Where # is the number you assigned it.

swapon /dev/vgXX/lvswap
or
swapon -a #This turns on all of your swap devices.

swapinfo -mt # Your current swap device information will be displayed.

Hope this helps
