increasing the of /tmp

[GNOM]

Hi all ,

I must increase the size of the /tmp file system on HP-UX 11.11. HOW can I perform this job. Thanks for your help !!!

Personally, I would do this on a Friday afternoon when the users have finished early - I can then reboot the server first to make sure there are no processes writing to /tmp. But I don't know what time your users finish, so this may not be practical.

Assuming you can do this, I would use SAM as it is easier than the command line. SAM -> discs/filesystems -> logical volumes -> actions -> extend.

Select the lvol containing /tmp (this should be displayed) and you will be guided through the next steps.

Hi

you cant extend the /tmp is when the system is up and running , unless you have online-jfs .

if you have online-jfs you just need to do this :

lvextend -L newsize /dev/vgXX/lvolX
fsadm -F vxfs -b newsize

if not , you need to boot to single username , do lvextnd -L newsize
( remember that when issue lvextend the new size is with m.b )

so the commands are :

lvextend -L larger_size /dev/vg00/lvol1

extendfs -F hfs /dev/vg00/rlvol1

mount /dev/vg00/lvol1 mount_directory

hi,

check how much free space in vg00
#vgdisplay vg00
total free space=free extents*1 extents size.
check any users or processes are accessing /tmp

#fuser -cu /tmp

if any processes or applications are accesing /tmp --shutdown that process or applications.

again if any users are accessing the /tmp
then (assuming /dev/vg00/lvol6 is your /tmp as per standard confogurations.)

#fuser -ku /dev/vg00/lvol6

then
#umount /tmp
#lvextend -L size-in-MB /dev/vg00/lvol6
#extendfs -F vxfs /dev/vg00/rlvol6
#mount -a

warning:- remember extendfs is usring rlvol6 and not lvol6.

size-in-MB is the new size of the lv which should be larger than current size.it should be specified in MegaBytes.

hi,

if you are using online-jfs in your system the do the following

#fsadm -F vxfs -b size-in-MB /tmp

note: fsadm: /dev/vg00/rlvol6 is currently 32768 sectors - size will be increased
fsadm: attempt to resize /dev/vg00/rlvol6 failed with errno 28
You may get this type of message if you are trying to extend a filesystem that is 100% full. If that is the case, you must get the usage % below 100, to 98 or 99, and then try your fsadm command again.


regds,

Before you go too far, I think it's worth pointing out that /tmp isn't always lvol6: I've looked at two of my systems and on one it's lvol4 and the other lvol5.
