Re: lvextend command

You need to say

"extend to" but not
"extend by" ...

So increase the number (3072 + x) !

Hope this helps!

Torsten.

Re: lvextend command

Hi,

You are trying to "extend" a logical volume to a smaller size, which it is not possible. If you want to extend the lvol (increase its size) you have to put a bigger size than its current size. In the command "lvextend" the "-L SIZE" means the TOTAL size (its current size plus the amount of space you want to add)

Re: lvextend command

Yes, if the size is currently "x", you need to specify "x+y=new total size" with lvextend:

lvextend -L ...

Hope this helps!

Torsten.

Daniel,

> LogicalExtentsNumber" is not bigger than current setting.

Seems your command to extend the FS is wrong, and not more than the current size of the LV.





Following to be check/done:
- What is the current size of the LV lvignite

# To check with :
# lvdisplay /dev/vg00/lvignite

Suppose 2GB



- What size you want to add more to it.
suppose 2GB. (Check free space on the vg as well)



- So your command will be:
# Syn# lvextend -L <(2GB+2GB)M> lvol_name
i.e
# lvextend -L 4096M /dev/vg00/lvignite



I Hope this helps,
Raj.

Re: lvextend command

you need to use below command

lvextend -L (current size + how much you want to extend) < lv name>
