fsadm error

carl_46 — Sun, 16 Jul 2000 15:29:47 GMT

fsadm -F vxfs -b 800000 /var
fsadm: /dev/vg00/rlvol7 is currently 716800 sectors - size will be increased
write failure at block 4994302 : No such device or address

Any ideas?

Regards

Check the size of /var using bdf. If you don't have a enough space there you might get that error, and also if you extended the filesystem to another disk.

Seb,

Sounds like the logical volume isn't big enough. You did increase it first?

check with

lvdisplay /dev/vg00/lvol7

It should be 800MB from what you typed into fsadm

I agree. First extend your LV and *then* the filesystem in it.
Be also careful about rounding issues in the filesystem sizes. If you are sure to have say 12345678 blocks and it fails, try 12345677. Sometimes works better ;-)

Hope it helps, Emmanuel

I usually use bc to compute the exact sector size. The number is 1024*MB. Since I generally build by extent rather than MB value, I use 4096 (assuming a generic build).

#echo 4096*92 | bc
376832

for example (a 92 extent lv). Then I plug that value into fsadm -b.

I use the following method to resize filesystems with OnlineJFS

1) use lvextend to resize the logical volume
2) use the command fsadm to resize the filesystem and compute the new size with $((size_in_mb * 1024))

example:
>bdf | grep var
/dev/vg00/lvol7 770048 600419 159364 79% /var

size of /var is 770048 kbytes
let's assume, i want to increase it to 800 mbytes

>lvextend -L 800 /dev/vg00/lvol7

>fsadm -F vxfs -b $((800 * 1024)) /var

Hi,
/var LV is just 716MB and your are trying to extend the filesystem to 800MB.
First extend the logical volume by issuing the following command.

# lvextend -L 800 /dev/vg00/lvolx /dev/dsk/cxtydz

then retry fsadm command.

whatever may be the block size of the filesystem, you should give the no. of blocks in 1 KB size.

i.e If you want to extend 716MB filesystem to 800MB.
No.of blocks = 800*1024 = 819200

fsadm -F vxfs -b 819200 /var

All the best

first you should extend the Logical Volume before trying to extend File system
use "lvextend -L 800 /dev/vg00/lvol7" and then use "fsadm -F vxfs -b 819200 /dev/vg00/rlvol7" command to extend the file system.

Silly me to mention, you should have Online JFS product installed on the system to perform extending the file system Online.
