How to increase the filesystem with Online JFS?

[Gulam Mohiuddin]

I would like to online extend the existing filesystem to 6GB more with OnlineJFS.

The filesystem /exports is mounted on /dev/vg02/lvol18.

--- Logical volumes ---
LV Name /dev/vg02/lvol18
LV Status available/syncd
LV Size (Mbytes) 8128
Current LE 2032
Allocated PE 2032
Used PV 1

rpludb02:/#bdf /exports
Filesystem kbytes used avail %used Mounted on
/dev/vg02/lvol18 8323072 5110822 3011494 63% /exports

Thanks,

Gulam.

# lvextend -L 14000 /dev/vg02/lvol18

# fsadm -b 14000m /exports

# bdf /exports

You are now done.

fsadm -F fstype -B
fsadm -F vxfs -B 60000 /dev/vg02/lvol10

Can not be used to expand root fs

Typo alert. My post should have said lower case -b. Apologies.

Hi,
The easiest way is to use SAM. Start SAM, select "Disks and Filesystems", select "Logical Volumes", select the locical volume you want to extend and then select "Increase size" from the Actions menu.

I did as mentioned above but got the following message. It didn't increase the filesystem size?


rpludb02:/#fsadm -F vxfs -b 8192m /exports
vxfs fsadm: /dev/vg02/rlvol18 is currently 8323072 sectors - size will be increased
rpludb02:/#
rpludb02:/#bdf /exports
Filesystem kbytes used avail %used Mounted on
/dev/vg02/lvol18 8388608 5110838 3072919 62% /exports

Gulam.

YOu didn't follow my post. You HAVE to do an 'lvextend' FIRST. BEFORE you try an fsadm.

Look at my post again and follow it. Note that the numbers I mention are the NEW SIZE you want the filesystem and LV to be.

[Alex Lavrov.]

Did you extend the logical volume?

First of all you should extend lvol, as it was posted above with "lvextend" command and then use fsadm, to extend the file system.

Lvol must be equal or bigger than file system

Yes, I did the same as instructed, see:

rpludb02:/#bdf /exports
Filesystem kbytes used avail %used Mounted on
/dev/vg02/lvol18 8323072 5110822 3011494 63% /exports
rpludb02:/#lvextend -L 8192 /dev/vg02/lvol18
Logical volume "/dev/vg02/lvol18" has been successfully extended.
Volume Group configuration for /dev/vg02 has been saved in /etc/lvmconf/vg02.conf
rpludb02:/#fsadm -F vxfs -b 8192m /exports
vxfs fsadm: /dev/vg02/rlvol18 is currently 8323072 sectors - size will be increased

You only expanded it from 8,128 MB to 8,192 MB. YOu said you wanted an additional 6,000 MB, which would be a total of about 14,000 MB.

You need to re-run the commands with the correct size information.
