Question How to increase rootfs space on NAS?


Dear gurus,

I am using NAS with Linux BizNAS-02H5 3.2.0-4-amd64 #1 SMP Debian 3.2.54-2 x86_64 GNU/Linux OS version.

I am facing problem with rootfs / , it is 100% full, its total size is 9.7GB.

Now i want to increase the space of rootfs, i have free space on attached drives, both partioned and unpartioned space is free,

How can I mount space on root folder or ( / ) folder.

Regards,

Khurram Khurshid

Do you have free space just after your / partition?
If so, you can use gparted from a live distro to increase the / partition.

Alternately, you if / includes /var then you could free up space with
Code:
sudo apt-get clean
This will remove all package downloads (but not the packages themselves).
The space savings can sometimes be considerable.

Dear Jeremy thanks for the reply, but its not applicable in my environment, as I told in my early post I am using NAS so there is no GNOME or other graphical interface, i have to connect through Putty.

there is less than 130MB users by /var folder.

You can use Gparted to move/resize the partitions.

You can start Gparted from a CD: http://sourceforge.net/projects/gpar...d-live-stable/

or you can install it from command line by: apt-get install gparted.

*nix is case sensitive - Gparted is not the same as gparted.
If the only access you have is ssh, then gparted will not change mounted partitions. Too little (no) information to make sensible suggestions. Post the output of these
Code:
df -hT
lsblk
parted /dev/sda "print free"

This won't work - even if you were able to install gparted.
You need to unmount any partition to be resized.

Do you have enough space to create a new bigger root partition?
You could restore a full backup of the old root to the new root, on a file by file basis.
Perform a couple of necessary changes to a couple of config files to point to the new partition.
Then reboot.

Other people may have simpler or much better ways of accomplishing the above.

I believe this is a Tandberg device. If not please post the make/model.

The NAS is an appliance with ssh access only so typical desktop methods will not work. As stated there isn't enough information provided to know how the device is configured. I did discover that when the disks are built the firmware copies its operating system to a hidden raid. I would expect during the build process that all available space would be used.

It might be possible to add space to the raid.

Check /var/log to see if any are failing to rotate. I would also find the largest files.

By the way you can install packages but the device needs to be configured first.
