i have to increase 5gb to /dev/testvg01/lvol1

I have tried this command

#lvextend -L 900 /dev/testvg01/lvol1
Warning: rounding up logical volume size to extent boundary at size "928" MB.
lvextend: "LogicalExtentsNumber" is not bigger than current setting.

You need to specify the total size at the end with lvextend, not "increase by".

"lvextend -L 900 /dev/testvg01/lvol1" means "increase the size of /dev/testvg01/lvol1 to 900 MB".

The upper-case option "-L" specifies the new size in megabytes; the lower-case "-l" specifies the new size as a number of extents.

Your "bdf" output indicates the LV is already bigger than that (its current size is about 24 000 MB), so your command makes no sense.

First lvextend tells you it must round the value 900 MB to the nearest multiple of 32 MB (the PE size), then it notices the problem (you're asking to make the LV smaller than it already is) and stops before doing anything.

I guess you wanted "lvextend -l 900 /dev/testvg01/lvol1"?

If you want to increase the size by 5 Gb then,

lvextend -L 5120 /dev/testvg01/lvol1

Provided you have space in the VG.

-L specifies the resultant LV size in MB

Hi sorry

I have done one mistake

i have lvextend -L 900 /dev/testvg01/lvol1
given pv size but normally we given byttes size know! that is the problem

after i given below command

#lvextend -L 28672 /dev/testvg01/lvol1Logical volume "/dev/vg00/lvol6" has been successfully extended.
Volume Group configuration for /dev/testvg has been saved in /etc/lvmconf/vg00.con

before this is 23gb now i extend 28gb

now lvextended

i sorry

try this...
#lvextend -L 5120 /dev/testvgo1/lvol1

or else if you want do do in extent no level
#lventend -l 160 /dev/testvgo1/lvol1..

i hope this will work out and make your LV as 5GB
& dont forget to increase the file system too...
