nas 326 - resize of volume seems not to work

pingpong

I try to resitze a exisitng volume after I have replaced a older smaler disk group with newer bigger disks. The screen "Volume on disk group" does not show any extention for the volume I have extended. Even though the dialog does not show an error. But the size of the volume is kept unchanged.Same problem like https://homeforum.zyxel.com/discussion/comment/5867

But I was not able to solve it.

I found a solution myself. The solution is described here

You may follow the sequence. But you need to find "your" volume which needs to be expanded.

Here is what I did:

logon via putty as "root"

run "lvdisplay "

  Now I got all Logical volume which might be in scope.

Now follow the sequence:

1. ran "vi /etc/init.d/rc.shutdown". 

2. Pressed "i" on keyboard. 

3. Look for "#swapoff" and pasted theses lines after that line: 

/sbin/telnetd 

/bin/sh 

1. Pressed ESC-key and then typed and ran ":wq". 

2. Run "poweroff"  in the shell
   

3. Closed Putty. 

4. Opened Putty once again, using the same IP and Port, but select "Telnet" instead of "SSH" as Connection type. A new command window opened and I had to login as "root" again. 
   

5. Pasted and ran "umount /i-data/sysvol" 

Now try "resize2fs" for all logical volumes from above until you find a ogical volume to expand. Copy the volume names from above.

~ # resize2fs /dev/vg_a246bbf1/lv_d648b119

resize2fs 1.42.12 (29-Aug-2014)

The filesystem can be resize to 525860864 blocks.chk_expansible=0 

Resizing the filesystem on /dev/vg_a246bbf1/lv_d648b119 to 525860864 (4k) blocks.

The filesystem on /dev/vg_a246bbf1/lv_d648b119 is now 525860864 (4k) blocks long.

~ # resize2fs /dev/vg_a246bbf1/lv_a4b19a90

resize2fs 1.42.12 (29-Aug-2014)

The filesystem is already 450883584 (4k) blocks long.  Nothing to do! 

~ # resize2fs /dev/vg_a246bbf1/lv_067dd4d6

resize2fs 1.42.12 (29-Aug-2014)

The filesystem is already 524812288 (4k) blocks long.  Nothing to do!

Rebbot the NAS by pressing the "poweroff" button on the device.

Vola. You are done. The volume should be expanded.
