Increasing tmp space

[Jonathan Tan]

Hi all, I am trying to increase my /tmp size.

I have the following Logical volumes read from SAM

lvol6 vg00 VxFS 32 0 /tmp
lvol6 vg01 Unused 32 0
lvol6 vg02 Unused 1500 0

Does this mean I can increase the size of /tmp with the remaining unused 1500?

Can kindly advise the steps?

Thank you very much!

To add on to the above, is it possible to migrate /tmp to the following:

lvol9 vg00 Unused 1500 0 lvol9 vg01 Unused 1500 0

Thanks!

You cannot assign free space from one VG to another.

Do you have any unused space in VG00?

vgdisplay -v vg00

Hi guys, I tried to follow a step mentioned in link provided by rariasn

------------------------------------------
1. Create a LV on VG01 with sufficient space that you need.
2. Edit /etc/fstab so that it contains /tmp pointing to the new LV.
3. Reboot the machine.
------------------------------------------

Found a unused LV, created VxFS (newfs) on it and edited FSTAB and rebooted...

lvol9 vg0 Unused 1500 lvol9 vg01 Unused 1500


When mounting I get the error and /tmp is mounted on root LV instead.

Mount file systems
Output from "/sbin/rc1.d/S100localmount start":
----------------------------
mountall: cannot mount /dev/vg00/lvol9
mountall: diagnostics from mount
mount - not a valid vxfs file system

Am I missing a step here?

I think I resolved the fsck issue. I did a another newfs for the lvol9 and now able to mount /tmp to it after a reboot.

Thanks all for your help!
