I installed the Eucalyptus FastStart Image to familiarize myself with Eucalyptus, but for some reason the NC doesn't detect the correct disk size:

My root-disk was to small for the /var/lib/ so I mounted another 4TB device to /var/lib/eucalyptus
# cat /etc/fstab | grep euca

Is there something wrong with my /var/lib/eucalyptus mount? I unmounted this partition and checked the /var/lib/eucalyptus folder on / which is empty. So the NC can't work at the root partition.
In /etc/eucalyptus/eucalyptus.conf the INSTANCE_PATH is set to: "/var/lib/eucalyptus/instances"
Do you see whats wrong with my setup or do I deal with a bug here?
Thanks for your help in advance!
I think your /var/lib/eucalyptus mount of 4TB is fine.
Eucalyptus won't automatically grab the entire filesystem, at least beyond a certain size.
You may want to take a look at the NC's /etc/eucalyptus/eucalyptus.conf file. These sections should be present (unless you did a Faststart install):
https://github.com/eucalyptus/eucalyptus/blob/e363faae31a26fe630c353a88638db4bf51153a9/tools/eucalyptus.conf#L102-110
Check out the (commented-out) NC_WORK_SIZE and NC_CACHE_SIZE settings. Uncomment them, and set them as appropriate (per the comments noted within the baseline eucalyptus.conf file, linked-to above).

I have an EC2 instance with 2 EBS volumes. On the root volume, I increased the volume size.
First I modified the volume size on console. Then followed this instruction to extended the partition following this instruction.
However, when running any command, I get No space left on device.
echo "Hello" > hello.txt
-bash: hello.txt: No space left on device
The df -h correctly shows, the total space correctly.
$ df -h

The bottom of the guide said,
If the increased available space on your volume remains invisible to
the system, try re-initializing the volume as described in
Initializing Amazon EBS Volumes.
So I followed the instruction to reinitialize the volume.
I used dd to reinitialize.
sudo dd if=/dev/xvda of=/dev/null bs=1M

30720+0 records out
32212254720 bytes (32 GB, 30 GiB) copied, 504.621 s, 63.8 MB/s
However, I still get "No space left on device" error. I have done multipe reboot of the instance, I still see the same error.
Update 1: I have a large number of small files 4-10KB. So, I am running out of inodes. Please let me know how to increase the inodes (on ext4 partition)? Thanks.

Please let me know how to resolve this error.
You don't need to reinitialise the volumes if you are using the new generations EC2 instance type like M4, M5, T2 and T3.
You have to also expand your volume on EC2 instance:
https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/recognize-expanded-volume-linux.html
As I can see your Inode is full, try this command to find the directory:
for i in /*; do echo $i; find $i |wc -l; done
Then, after finding the directory, do:
for i in /path/to/directory/*; do echo $i; find $i |wc -l; done
After that remove those file using:
rm -rf /path/to/fileorfoldername
As you don't want to remove the files, you will have to create a new filesystem using mke2fs and -I parameter for inode size, or keep increasing your root volume more.
Here is a similar question for it:
https://unix.stackexchange.com/questions/26598/how-can-i-increase-the-number-of-inodes-in-an-ext4-filesystem
Also, you can move your files to secondary drive.
You are running out of inodes on your / (root) directory. so to debug it, you need:
Find what are the inodes pointing to or open files something like for i in /*; do echo $i; find $i |wc -l; done
Now look for directories which take more time and then delete that dir
I'm new to programming and i have programmer some share memory on my beaglebone black which runs on Linux.
I need to make sure that the memory is saved on the Beaglebone blacks ram, and not flash.
The filepath is:
#define FILEPATH "/tmp/mmapped.bin"
fd = open(FILEPATH, O_RDWR | O_CREAT | O_TRUNC, (mode_t)0600);
if (fd == -1) {
perror("Error opening file for writing");
exit(EXIT_FAILURE);
}
coded in C++
Please let me know if any further questions are needed.
The file path /tmp/whatever does not guarantee anything. What you need to do is log into your Beaglebone and see what filesystems are mounted where.
In order to store files in RAM you need to store them on a tmpfs or ramfs filesystem.
On my Fedora Linux laptop if I type mount or cat /proc/mounts I see everything that is mounted. These are the kinds of lines you're looking for:
$ grep tmpfs /proc/mounts
tmpfs /dev/shm tmpfs rw,seclabel,nosuid,nodev 0 0
tmpfs /run tmpfs rw,seclabel,nosuid,nodev,mode=755 0 0
tmpfs /sys/fs/cgroup tmpfs ro,seclabel,nosuid,nodev,noexec,mode=755 0 0
tmpfs /tmp tmpfs rw,seclabel,nosuid,nodev 0 0
So you can see that on Fedora anyway, the /tmp/ directory is a tmpfs and the files in /tmp/ will be in RAM.
One thing to watch for with tmpfs is that the default maximum size is half of RAM. If a file in tmpfs, plus programs using RAM exceeds the RAM size the tmpfs data will go into swap, which will be on Flash, if a Beaglebone even has swap, which I don't remember at the moment.
If there's no swap or it is small then using a tmpfs for big files will cause OOM (out of memory) and break a lot of things so be careful how much you use.
I have one amazonw ec2 instance and would like to extend root device device form 100G to 500G. After create a new 500G volume and reattached to instance.

Before resizing the filesystem by "resize2fs" command you should first resize your partition:
let's list block devices attached to our box:
lsblk
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
xvda 202:0 0 16G 0 disk
└─xvda1 202:1 0 8G 0 part /
As you can see /dev/xvda1 is only 8 GiB partition on a 16 GiB device and there are no other partitions on the volume.
step-1) We will use "growpart" to resize 8G partition up to 16G:
# install "cloud-guest-utils" if it is not installed already
apt install cloud-guest-utils
# resize partition
growpart /dev/xvda 1
Let's check the result (you can see /dev/xvda1 is now 16G):
lsblk
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
xvda 202:0 0 16G 0 disk
└─xvda1 202:1 0 16G 0 part /
Lots of SO answers suggest to use fdisk with delete / recreate partitions, which is nasty, risky, error-prone process especially when we change boot drive.
step-2) resize file system to grow all the way to fully use new partition space
# Check before resizing ("Avail" shows 1.1G):
df -h
Filesystem Size Used Avail Use% Mounted on
/dev/xvda1 7.8G 6.3G 1.1G 86% /
# resize filesystem
resize2fs /dev/xvda1
# Check after resizing ("Avail" now shows 8.7G!-):
df -h
Filesystem Size Used Avail Use% Mounted on
/dev/xvda1 16G 6.3G 8.7G 42% /
And by the way, there's no need to stop instance and detach EBS volume to resize it anymore! 13-Feb-2017 Amazon announced: "Amazon EBS Update – New Elastic Volumes Change Everything" See my other SO answer for details.
Update: Use sudo xfs_growfs /dev/xvda1 instead of resize2fs when XFS filesystem
This answer is dangerous, hasn't been verified since 2016, and has the potential to delete your partition if you're not aware of what's happening. Use with caution, and please reference #Dmitry's answer below as well.
To expand on JD's answer, here's exactly what to do:
df -h #print the name of your boot partition
lsblk #show info on all your block devices
You'll see from that output what the name of the disk is of your root partition. For example, you probably see something like this:
xvde 202:64 0 32G 0 disk
└─xvde1 202:65 0 8G 0 part /

p #Primary partition
1 #Partition number

Press Enter to accept the default
p #Print info
a #Toggle the bootable flag
1 #Select partition 1
w #Write table to disk and exit
Now, reboot your instance:
reboot
After it comes back do:
resize2fs /dev/xvde1 (the name of your partition, not the block device)
And finally verify the new disk size:
df -h
After searching and searching with no answer here, i FINALLY came across the answer!
"fdisk, put it into 'units' mode by typing 'u' then 'p' to print the partition table as it is now and write down the starting sector of the existing partition. Then delete that partition and make a new one, with the same partition number and starting on exactly the same sector and ending at the end of the disk, make sure that partition is 'active' then save your changes and reboot. Once you reboot after that, you should be able to resize2fs the existing filesystem to take up all space. Backups are recommended and it's your data to lose!!"
Putting it into sectors via Units mode helped me select the proper start and end of the FS!!

I know the question is answered already. But still, if someone is stuck with the problem and need a more detailed step by step explanation. You can check out the official Amazon docs. This has the steps to increase the size and specific commands if you are using the "ec2-user (amazon ami)" instance.
https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/recognize-expanded-volume-linux.html
also if you are using windows instance. You can visit
"For information about extending a Windows file system, see Extending a Windows file system after resizing a volume in the Amazon EC2 User Guide for Windows Instances."
https://docs.aws.amazon.com/AWSEC2/latest/WindowsGuide/recognize-expanded-volume-windows.html

I'd like to give my box some more disk space. I'm trying to do this through the vagrantfile as follows:
Vagrant::Config.run do |config|
# ..
config.vm.customize ["modifyvm", :id, "--memory", 1024]
config.vm.customize ["modifyhd", :id, "--resize", 4096]
end
This gives me the error:
A customization command failed:
["modifyhd", "e87d8786-88be-4805-9c2a-45e88b8e0e56", "--resize", "4096"]
The following error was experienced:
VBoxManage: error: The given path 'e87d8786-88be-4805-9c2a-45e88b8e0e56' is not fully qualified
VBoxManage: error: Details: code VBOX_E_FILE_ERROR (0x80bb0004), component Medium, interface IMedium, callee nsISupports
VBoxManage: error: Context: "OpenMedium(Bstr(pszFilenameOrUuid).raw(), enmDevType, enmAccessMode, fForceNewUuidOnOpen, pMedium.asOutParam())" at line 178 of file VBoxManageDisk.cpp
Please fix this customization and try again.
I'm trying to piece the information together from http://docs.vagrantup.com/v1/docs/config/vm/customize.html
http://www.virtualbox.org/manual/ch08.html#vboxmanage-modifyvdi
You are sending modifyhd the UUID of the VM (provided by vagrant) while it expects the UUID of the VDI.
You will need to use the absolute path to the actual VDI file or its UUID. You can use the following command to get the UUID of the VDI: VBoxManage showhdinfo <filename> (see virtualbox - how to check what is the uuid of a vdi?)
I created a new disk, added and extended the older.
My Vagrantfile:
Vagrant.configure(2) do |config|
config.vm.box = "bseller/oracle-standard"
config.vm.define :oracle do |oracle|
oracle.vm.hostname = 'oraclebox'
oracle.vm.synced_folder ".", "/vagrant", owner: "oracle", group: "oinstall"
oracle.vm.network :private_network, ip: '192.168.33.13'
oracle.vm.network :forwarded_port, guest: 1521, host: 1521
oracle.vm.provider :virtualbox do |vb|
vb.customize ["modifyvm", :id, "--memory", "4096"]
vb.customize ["modifyvm", :id, "--name", "oraclebox"]
if !File.exist?("disk/oracle.vdi")
vb.customize [
'createhd',
'--filename', 'disk/oracle',
'--format', 'VDI',
'--size', 60200
]
vb.customize [
'storageattach', :id,
'--storagectl', "SATA",
'--port', 1, '--device', 0,
'--type', 'hdd', '--medium', 'disk/oracle.vdi'
]
end
end
oracle.vm.provision "shell", path: "shell/add-oracle-disk.sh"
oracle.vm.provision "shell", path: "shell/provision.sh"
end
end
This will create new disk in
disk
|-- oracle.vdi
shell
|-- provision.sh
Vagrantfile
and add in your box. The new disk is of 60GB
My shell provision.sh
set -e
set -x
if [ -f /etc/disk_added_date ] ; then
echo "disk already added so exiting."
exit 0

I've been looking at this, and I haven't found any way to actually do this directly. However, you can achieve the effect using Ansible as a provisioner. First of all, it is definitely possible with Vagrant to create and add a second disk, which you can then add and mount any way you like using Ansible.
However, Ansible also has the ability to run local commands (on the host). This is with Ansible's local_action feature. I used it here to reboot a Vagrant VM after a kernel upgrade and tell the host to wait until it has restarted, but you could use this with the command or shell actions to find the HD identifier, shutdown the VM, and configure the hard disk, then reboot. At least in theory.
Although the question is old but I saw no answer accepted.
The given path 'e87d8786-88be-4805-9c2a-45e88b8e0e56' is not fully qualified shows up because the UUID e87d8... is VirtualBox vm UUID, not your SATA storage disk device UUID. You an find the storage device UUID by VBoxManage showvminfo e87d8786-88be-4805-9c2a-45e88b8e0e56|grep vdi. The replace :id with the SATA storage UUID in Vagrantfile modifyhd line.
It solved my problem.
OK... Solved...
VBoxManage.exe wan't in my path so what I did was go to (you have to go to that path):
C:\Program Files\Oracle\VirtualBox
then used the command:
VBoxManage.exe modifyhd "C:\Users\MyUser\VirtualBox VMs\MachineName\HDName.vdi " --resize 20480
For 20 GB size a HD
This DON'T work:
"C:\Program Files\Oracle\VirtualBox\VBoxManage.exe" modifyhd "C:\Users\MyUser\VirtualBox VMs\MachineName\HDName.vdi " --resize 20480
You have to be in the path: C:\Program Files\Oracle\VirtualBox
You can add new disk instead.
First use virtual box GUI to add another
virtual disk
then use fdisk to create a primary disk partion
