help on fsdam

[uadmin]

Hi
I am trying to exend a volume using fsadm and can not get what block size i require.
I have done a lvextend -L 300 /dev/vg00/lvol8
now i need to run fsadm -F vxfs -b < block size > /dev/vg00/rlvol8.

if i look at a lvdisplay i get the following :--- Logical volumes ---
LV Name /dev/vg00/lvol8
VG Name /dev/vg00
LV Permission read/write
LV Status available/syncd
Mirror copies 0
Consistency Recovery MWC
Schedule parallel
LV Size (Mbytes) 1012
Current LE 253
Allocated PE 253
Stripes 0
Stripe Size (Kbytes) 0
Bad block on
Allocation strict
IO Timeout (Seconds) default

--- Distribution of logical volume ---
PV Name LE on PV PE on PV
/dev/dsk/c0t6d0 253 253

Can you please tell me where i get the current size from so i can * new size.

Thanks
Simon

Your LV is currently 1012 MB (253 LE/PE * 4 MB per extent)

By running lvextend -L 300 /dev/vg00/lvol8, you are trying to extend the LV to 300MB which is smaller than it's current size of 1012MB. You should have got an error message like the following
lvextend: &quot;LogicalExtentsNumber&quot; is not bigger than current setting.

Since you are using fsadm then it meanshave online jfs install and you are trying to extend your filesystem online.

if /dev/vg00/lvol8 mount to /home
lvextend -L 300 /dev/vg00/lvol8
fsadm -b 300M /home

This should work for you.

I'm not sure you can use -b 300M with fsadm, as -b means the number of 1kB sectors (in this case 300*1024=307200). I'm sure that
#fsadm -b 307200 /home
will work.
