Dear all,

I would like to extend the disk capacity of a container. The container conf file is:

I am affraid I only get 550 GB, at maximum, independetly of the amount I specify (600 GB, 700 GB, ...).

Let me show you the hardware server disk occupation:

I would appreciate any help you may provide me with.

you only have 176G free space on the disk.

 

[JMoreno]

Hi Dietmar,

Thank you for your reply.

Yes, I wanted to extend 50 GB only. Indeed, you can see in the conf file I already gave 600 GB, but I only get 550 GB.

Regards.

Hi, I'm not an expert, but

how do you check free space inside CT, exactly? df -h?

[edit] sorry , I meant how do you check assigned disk size from inside CT

Marco

 

[JMoreno]

Yes, I am using "df -h".

You can use it from the container itself or from the hardware server. In second case, you will get the disk space usage of the hardware server and the running containers.

 

[m.ardito]

ok, I only have CT on shared storage (lots of free space), assigned 8GB to a CT but I get

/# df -h
Filesystem      Size  Used Avail Use% Mounted on
/dev/simfs      9.4T  5.4T  4.1T  57% /
none            512M  8.0K  512M   1% /dev
none            103M  988K  102M   1% /run
none            5.0M     0  5.0M   0% /run/lock
none            512M     0  512M   0% /run/shm

so I wonder what you get as "size"...

Marco

 

[JMoreno]

Hi Marco,

Let me provide you with (run from inside the container):

root@myserver:~# df -h
S.ficheros            Size  Used Avail Use% Montado en
/dev/simfs [COLOR=#ff0000]           550G  [/COLOR]374G  176G  69% /
tmpfs                 5,0G     0  5,0G   0% /lib/init/rw
tmpfs                 5,0G     0  5,0G   0% /dev/shm

Thank you very much.

 

[m.ardito]

It could be that the CT gets as "size" the sum

CT used space + HOST free space = "fake" size
eg:374G + 176G = 550G

no matter of what you set in conf (which is the maximum)

but not sure...

Marco

 

[JMoreno]

I believe it is not the case. If I set a 500 GB disk size, it reports the right value (ie 500 GB).

Regards.
