How to increase /tmp filesystem

[Carles Viaplana]

Hello,

I need to increase /tmp filesystem but as this is nounted in vg00 and used by system I can't do it as usual.

What's the procedure to increase vg00 filesystems?

Thanks in advance for your help.
Regards,

Carles

lvextend -L Megabytes /dev/vg00/lvol
extendfs
Must umount before using extendfs

You can't extend root this way.

If you have online JFS installed on the system then you can do it online.

lvextend -L /dev/vg00/lvol6
fsadm -F vxfs -b$((1024*totalsize)) /tmp

HI:

If you don't have OnlineJFS, then boot into single user mode and use 'lvextend' and 'extendfs'. These commands reside in '/sbin' as well as '/usr/sbin' so you can do this type of operation easily. Once done, reboot for normal startup.

If all else fails:
to bring the system up in single use mode
mount /usr (so you have access to the appropriate commands)
extend /tmp
reboot the server and bring it up normally

Hi Carles,

You have to be able to unmount /tmp before you can extend the file system.

lvextend -L "Megabytes size" /dev/vg00/lvo4
extendfs
mount filesystem

Thanks to all for your help.

Finally, I reboot system in single user mode and then I'll increase size.
