I am trying to extend my filesystem.. the disk has 146 gb cap... and wanted to allocate 100GB

I went through man vgextend.. could only was able the system upto 10 gig...I want to extend it to 100gig

Please advide

# lvextend -l 3749 /dev/vg01/oracle
lvextend: "LogicalExtentsNumber" is not bigger than current setting.

Did it occur to you to actually READ THE man PAGE for lvextend before posting?

from man lvextend:

-l le_number Increase the space allocated to the logical
volume, specified in logical extents.
le_number is a decimal value greater than the
current number of logical extents.

le_number must be at least 1 and no greater
than a volume group version-dependent
maximum; use the lvmadm command to determine
the maximum number of logical extents for the
volume group version.

One, and only one, -l, -L, or -m option must
be supplied.


So you told the command to *extend* the LV to 3749 extents which is smaller than it currently is. Figure out how many extents equals 100GB and use that instead...

or to spell it out for you:

lvextend -l 6400 /dev/vg01/oracle

Please please please stop what your working on and spend some time reading the manuals

Try lvextend -L 102400m /dev/vg01/oracle

and then if you have onlinejfs

fsadm -b 102400m /mount_point

Usage: lvextend

{-l LogicalExtentsNumber |
-L LogicalVolumeSize}
LogicalVolumePath [ PhysicalVolumePath... | PhysicalVolumeGroupName... ]
"LogicalVolumeSize": Must be a value between 1 and 16777216 (16M).
# lvextend -L 16777216 /dev/vg01/oracle
lvextend: "LogicalExtentsNumber" is bigger than the maximum value allowed.
# lvextend -L 167772 /dev/vg01/oracle
Warning: rounding up logical volume size to extent boundary at size "167776" MB.
lvextend: Not enough free physical extents available.
Logical volume "/dev/vg01/oracle" could not be extended.
Failure possibly caused by strict allocation policy

Please give me the command for now.... I will research on it after I have given the system

I thought

lvextend -L 102400m /dev/vg01/oracle

was pretty explicit.

Thanks a lot Court Campbell.... You saved me...
