online JFS problem

[SSP_1]

Hi,

I am using online JFS to increase "var" filesystem size. Here are the steps which I follows :-

# fsadm -d -D -e -E /var
# fsadm -b 5000000 /var - to increase the size to 5GB. But it doen't go and gives me the following error :-

# fsadm -F vxfs -b 2205219 /var
vxfs fsadm: /dev/vg00/rlvol8 is currently 2097152 sectors - size will be increased
vxfs fsadm: write failure at block 6399521 : No such device or address



Is there any solution for this prob OR pl let me know how to use online JFS?

Have you extended the logical volume that var uses? that needs to be done first before you can extend the file system...

the -b option expects to be told the number of blocks in 1K blocks, so if you had extended your logical volume to size 5000MB, the fsadm command would be:

fsadm -F vxfs -b 5120000 /var

(5120000= 1024 * 5000)

Hi,
You've forgotten something essential. Before doing the fsadm-command, you need to lvextend the logical volume. Example :
root/sv00127#lvextend -L 240640 /dev/vghsmcaches2/lv_hsmcaches2
root/sv00127#fsadm -F vxfs -b 246415360 /dbad_migratie
root/sv00127#cd /dbad_migratie
root/sv00127#bdf .
Filesystem kbytes used avail %used Mounted on
/dev/vghsmcaches2/lv_hsmcaches2
246415360 136954080 108606168 56% /dbad_migratie

Hope this helps,

Hi


This is well documented at www.docs.hp.com

hi,

You seem to have missed the lvextend part!
Here is a useful link :

You may have forgotten to extend the lvol first:
lvextend -L 5000 /dev/vg00/lvol8

Then you need to extend the filesystem:
fsadm -F vxfs -b 5000M /var
If your HP-UX version don't support the M-option:
fsadm -F vxfs -b 5120000 /var

One other note.

If you did do the lvextend.

The filesystem can not be 100% full to extend the filesystem. It needs just a little bit of space in /var/lost+found.

Hi,
you need to do following :

1. You have to extend the logical volume on which you want to extend the file system.
#lvextend -L 5000 -n lv_name /dev/vgxx

#fsadm -F vxfs -b 5120000 /var


you are all set now.

HI Shripad

Alternatively have u tried using SAM , this would take you out many hardships that you may face.
