Hi All,
lvol3 can be extended if there is a free disk and free space available on root disk.Not sure whether it is supported/recommended.But it was success for me.

Steps Done.

1.Moved lvol4 to lvol8 to another disk using pvmove.
2.extended the lvol3 ( Online JFS )
3.moved back the lvols.(pvmove)

Rebooted and tested.All was fine.

Anybody tried this.
Can anybody suggest on this method.

Regards

Hi,

You can extend the / (root filesystem) /dev/vg00/lvol3 as decribed


1.Moved lvol4 to lvol8 to another disk using pvmove.
2.extended the lvol3 ( Online JFS )
3.moved back the lvols.(pvmove)

But this not a recommended method.....
And one more thing, here size of lvol3 is around 65MB. So you can extend lvol3 by a maximum of 65MB.
HP recommend to restore the ignite backup to extend root file system.
But before taking an ignite backup, make sure that your vg00 is error free..... Please post all the o/p as suggested by experts.....

Hi all,

To simplify what i want to do,

The directory /home are located under lvol3, and it 95% full

$bdf
Filesystem kbytes used avail %used Mounted on
/dev/vg00/lvol3 147456 140191 6867 95% /

md2:/home$df -k .
/ (/dev/vg00/lvol3 ) : 147088 total allocated Kb
6409 free allocated Kb
140679 used allocated Kb
95 % allocation used

so i want to extend it, but vgdisplay show error as above.

OK.... gd job.
But freeup some space is /dev/vg00/lvol3 (root). Its already 95%, otherwise you would be fell down to even big issue.... :)

Sen,

Size of lvol4 is 65 MB. While creating Lvol's PE's allocated in serial manner. After lvol4, the immediate PE would be already allocated to some other LV. As root file system demands continuous allocation of PE you cannot exceed the size of lvol4 (Here it is 65MB). Otherwise you have to delete subsequent LV.

Sreekanth,

I understood what 65 MB is.

What I have done is to move all LVs after lvol4..
ie..lvol3,lvol4,6,7,8 to another disk.

If enough space is there in the root disk, u can increase the size as much u want.

Thanks
