/opt

John Ramsay_1 — Thu, 04 Dec 2003 14:08:38 GMT

I increased my /opt but I still can't install mazilla. The Disk space analysis shows only 93k available but the vol is 1100 meg. This is a new load so I'm wondering where did the disk space go and why did the disk analysis not change even though I increased it by 300 megs?

John,

It sounds like you may have done an lvextend to increase the size of the "container" without doing an extendfs to increase the size of the actual contents.

What does bdf say about /opt ?

How you increased the filesystem by 300MB ?
Did you only increased the logical volume using lvextend ?

Thanks

What's the output of 'bdf'. How did you extend /opt? Did you forget to do 'fsadm' or 'extendfs' ?

Tell me more about extendfs...It looks like that is my problem

Hi,

Did you do a extendfs or fsadm -b after you did the lvextend.

If you have online jfs use "fsadm -b" to extend the size after lvextend. If not then you have unmount the filesystem, do a extendfs and then remount it.

Hope this helps.

what is the actual command line?

Hi,

Did you extend your filesystem like this example ?

# lvextend -L XXX /dev/vg00/lvolX

# extendfs /dev/vg00/rlvolx

# bdf

Hi John,

It would be like

fsadm -F vxfs -b 1100M /opt

NOTE the M after the 1100 - designates 1100 MB to the command. Must have OnLine JFS to do this.

HTH,
Jeff

If you have online JFS use this command to extend the filesystem:

fsadm -F vxfs -b /opt

If you don't have online JFS, then you need to increase the filesystem in single user mode. Use "extendfs -F vxfs /dev/vg00/rlvol6"

Note: I assumed the filesystem is vxfs and /dev/vg00/lvol6 is mounted to /opt

Thanks

Helen French — Thu, 04 Dec 2003 14:22:15 GMT

Try this:

# extendfs -F fs_type /dev/vgXX/rlvol?

If you had extended /dev/vg00/lvol7 and if that uses a vxfs file system, then try this command:

# extendfs -F vxfs /dev/vg00/rlvol7

Re: /opt

Pete Randall — Thu, 04 Dec 2003 14:22:36 GMT

John,

From "man extendfs":

umount /dev/vg00/lvol1

lvextend -L larger_size /dev/vg00/lvol1

extendfs -F hfs /dev/vg00/rlvol1

mount /dev/vg00/lvol1 mount_directory

Note that, in order to run this, you'll need to unmount the file system and, in order to do that, you'll need to go to single user mode (reboot, interrupt, interact with ISL, enter "hp-ux -is"), unless, of course you have OnlineJFS installed and can run fsadm against the mounted file system.

Sanjay_6 — Thu, 04 Dec 2003 14:22:45 GMT

Hi,

The command line for using fsadm if you have onlineJFS is,

fsadm -b size_in_1k_blocks /mount_point

Size in 1k blocks is : size_in_mb * 1024

Get the size in mb using lvdisplay command.

Hope this helps.

Oops.. some correction..

If you have online JFS use this command to extend the filesystem:

fsadm -F vxfs -b /opt

If you don't have online JFS, then you need to increase the filesystem in single user mode. Use "extendfs -F vxfs /dev/vg00/rlvol6"

Note: I assumed the filesystem is vxfs and /dev/vg00/lvol6 is mounted to /opt

Re: /opt

Geoff Wild — Thu, 04 Dec 2003 14:51:08 GMT

Or, like this:

lvextend -L 1100 /dev/vg00/lvol6

fsadm -F vxfs -b 1100M /opt

or, if no online jfs:

umount /opt
lvextend -L 1100 /dev/vg00/lvol6
extendfs -F vxfs /dev/vg00/rlvol6
mount /opt
