I'm using OpsWorks to manage my application instances. I have one Load Based EBS-backed instance that starts when load is high and stops when it's low. However, after instance is stopped and started again contents of /var is completely removed. df -h shows:
/dev/xvda1 7.9G 2.2G 5.4G 29% /
udev 3.7G 12K 3.7G 1% /dev
tmpfs 1.5G 188K 1.5G 1% /run
none 5.0M 0 5.0M 0% /run/lock
none 3.7G 0 3.7G 0% /run/shm
/dev/xvdb 414G 199M 393G 1% /mnt
so /var is not on ephemeral storage. Why?
OK, it seems that one of opsworks default recipes is mounting something (/mnt/var/www) to this folder. Solution was to use some other folder instead /var/www.

I'm trying to build a golang project on my gcp console. However when I run the build command I get the following error no space left on device, when I run the df command I see the following.
Filesystem Size Used Avail Use% Mounted on
overlay 60G 44G 17G 73% /
tmpfs 64M 0 64M 0% /dev

I'm not sure how to interpret this, and is there something I can do to free up some disk space? I assume this is the location /dev/disk/by-id/google-home-part1? I am trying to build the go project in the /home/user1/gopath directory.
The df command is showing that you have the /home directory full. You must free some space to use it.

I'm running the frontend part of a project which uses an Elastic search server on a VirtualBox instance.
This is the error I'm getting:
[FORBIDDEN/12/index read-only / allow delete (api)];].
Checking if there is enough disk space with df -h showed the following output:

Do I still need to add space to the VirtualBox instance? Trying to unlock indices with curl -XPUT -H "Content-Type: application/json" http://localhost:9200/_all/_settings -d '{"index.blocks.read_only_allow_delete": null}' returned curl: (7) Failed to connect to localhost port 9200: Connection refused. I'm not sure though if I specified the correct location and port.
How do I get the Elastic server to run?

I'm trying to install manjaro on laptop with oem windows 10 on board, I do it using
manjaro architect cli installer. I've created LVM, parted logical volumes, made luks on LVM, formatted partitions to btrfs and mounted it. When I moved next and began installing DE I caught the error:
checking available disk space...
error: Partition /mnt too full: 1333620 blocks needed, 0 blocks free
error: not enough free disk space
error: failed to commit transaction (not enough free disk space)
Errors occurred, no packages were upgraded.
==> ERROR: Failed to install packages to new root
Then I type df -hT and see this:

What is wrong with the row?
/dev/mapper/vg--default-lv--root btrfs 162G 1.1G 0 100% /mnt
How can it be so - Use% 100% and Avail 0, but only 1.1G is used from 162G?
The solution is to manually unmount and remount the filesystem before installing packages. Possibly, closing and reopening the btrfs volume is also necessary. If you run into the issue while packages are being installed, you can do the mount/remount and then just redo the package installation step without formatting.
Previously I wrote the following, however it did not help in a recent install:
I ran into the same issue. This is some sort of bug in btrfs. I stumbled upon a workaround. After manually creating a file and writing to it (touch /mnt/temp, dd if=/dev/zero of=/mnt/temp bs=1M count=1000), df began to report correct available space and I was able to resume the installation.
P.S. I am using btrfs directly over luks over block device.
I'm have deployed Hadoop in docker which is running on aws ec2 ubuntu AMI instance.
when I try to create a directory in hdfs it says Cannot create directory. Name node is in safe mode
below are the properties in hdfs-site.xml

name: dfs.namenode.name.dir
value: /usr/local/hadoop/data
when I check the hdfs report, it gives the below output.
