BUG when you upgrade the VPS
« on: August 23, 2016, 05:09:56 AM »
Hi

I have working a CWP in my VPS.
Today, I have upgraded my VPS and the CWP continue working, but the DISK DETAILS of the partition is wrong.

My virtual DISC ( 10 gb ) was full, 99%. Now I have 20gb and this is the info of the partition in CWP:

Code: [Select]

Fdisk info:
Disk /dev/vda: 21.5 GB, 21474836480 bytes
16 heads, 63 sectors/track, 41610 cylinders
Units = cylinders of 1008 * 512 = 516096 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x000574cf

   Device Boot      Start         End      Blocks   Id  System
/dev/vda1   *           3       20806    10484736   83  Linux

Software RAID:
Personalities :
unused devices:

Filesystem      Size  Used Avail Use% Mounted on
/dev/vda1       9.8G  4.7G  4.7G  50% /
tmpfs           1.9G     0  1.9G   0% /dev/shm

Now, the 50% I think is ok, but the size isn't.

Hello.

You have to make resize partitions manually. You can ask it your service provider or contact to CWP Support.

Hi

I think my new partition is 20gb,  the CWP is wrong when it show only 10gb.


It is wrong when it shows that 4'7gb are used.

I had 9'99 gb of my 10 GB used... upgrade to 20 GB of space and now I have ONLY 4'7 in use ?? It is impossible.

CWP is wrong.

cwp is reading system info live details so it's NOT wrong, you will need to resize this partition or you should ask you server provider to check it.

Ok, I think you are right.
Sorry for my doubts.

But when I try to resize the partition, I have the error 16.
So.. can I solve it if the CWP is in use ?  :'(

When I reboot the VPS, nothing is change.

Where is my problem?

This was my way:

Code: [Select]
[root@vps****01 ~]# df -h

/dev/vda1       9,8G  5,5G  3,8G  59% /

you can check it with your hosting provider as they should know how to do it or you can contact our managed support to check it.

I have not hosting support. It is my server.

I want to learn, I don't want to go to the support.

So...  Is impossible to resize a partition where the CWP is running actually ??? How can I do it ?

I have found  the solution:

It is very simple:

Code: [Select]
resize2fs /dev/vda1
 ;)

It can be useful for you.
