To extend root FS in preceding lvols

[Saurabh Rawat]

hi alll

I have a problem that my root fs is on lvol4 and swap is on lvol3 so I accidently increased the lvol3 to lvol4 which has no problems but now I want that space back on to root FS which is lvol4 but since it has contiguous policy so its not taking the space from the lvols preceding to the lvol4 rather its trying to take sapce from the next lvols e.g 5,6,7. Can anybody through light so that I can recover the free space from lvol3 and increase the root lvol4.

Your suggestions will be appreciated.

Thanks in Advance!!!

suggested to take an Ignite backup of the system and then do a Ignite restore to Reinstall on the system with the desired root disk configuration.

[Saurabh Rawat]

I dont think so!!!

[sujit kumar singh]

sorry wriring all these to an expert.

[Saurabh Rawat]

no id didnt mean that ... I wanted to say I cant ignite for this system now...

[Ganesan R]

Hi Saurabh,

The only recommanded way to extend the root filesystem is taking ignite backup and restore it with modified LV sizes. There are certain ways to extend it without ignite, but it is with your own risk.

You cannot move around the lv's to reduce the space and assign it to root lv, since root lv needs contigious space.

Hope this helps..

[sujit kumar singh]

r u using lvol2 and lvol3 both as swap?
if yes what are the sizes of them?

[Pete Randall]

Could you post the output of "lvdisplay /dev/vg00/lvol3",please. I don't see how you could have extended it if it was defined as strict/contiguous as it should have been.
