Hello! I have a strange issue in my elasticsearch cluster So I have 3 nodes, and each node server has 300gb disk space on it But it showed that only 20gb is available. ![Screenshot 2022-09-02 113125](https://us1.discourse-cdn.com/elastic/original/3X/2/9/29c2c1094c10d5fddcc6690932ed3f2a11b2da17.png) How I can add more space to the nodes? ---

Hello There! Have you checked it by FS information? ---

After executing this command: ```auto root@master-node:/# df -H /var/lib/elasticsearch/ ``` I get this output: ```auto Filesystem Size Used Avail Use% Mounted on /dev/mapper/ubuntu--vg-ubuntu--lv 21G 18G 2.6G 88% / ``` ```auto Disk /dev/mapper/ubuntu--vg-ubuntu--lv: 20 GiB, 21474836480 bytes, 41943040 sectors Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes root@master-node:/var/lib/elasticsearch# ``` ---

Your `/` volume is 21GB so it looks OK what ES shows. ---

Is there a possibility of allowing more than 20gb? ---

Could you please show results of `df -h` without any parameters? Let's see what you have got there. By the way - is it virtual machine? ---

I don't get it. Who installed this for you? This is how it looks at my machines: ```auto # df -h System plików rozm. użyte dost. %uż. zamont. na udev 3,9G 0 3,9G 0% /dev tmpfs 796M 520K 796M 1% /run /dev/sdc 20G 9,3G 9,3G 50% / tmpfs 3,9G 0 3,9G 0% /dev/shm tmpfs 5,0M 0 5,0M 0% /run/lock /dev/sdb 9,8G 2,7G 6,6G 29% /var/log /dev/sda 30G 24K 28G 1% /opt {{FQDN}}:/var/nfs/elasticsearch 20G 3,2G 16G 18% /var/nfs/elasticsearch tmpfs 796M 0 796M 0% /run/user/1001 ``` and: ```auto # lsblk NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT sda 8:0 0 30G 0 disk /opt sdb 8:16 0 10G 0 disk /var/log sdc 8:32 0 20G 0 disk / sr0 11:0 1 785,7M 0 rom ``` For this machine I use Debian 11 + LVM. ---

Same here, it seems weird. I deployed this VM (via Hyper-V) using a template. ---

Is it your test machine or production cluster? 🙂 ---

It's a test machine 😇 😇 😇 ---

I don't know how it's in Hyper-V but I would try to resize volume. Is Hyper-V says you got free space (or not allocated) left? ---

No, I didn't found such information. I find this article, explaining how to extend the volume: > **[How to Extend/Reduce LVM's (Logical Volume Management) in Linux - Part II](https://www.tecmint.com/extend-and-reduce-lvms-in-linux/)** > > In this article, we are going to see how to extend volume group, extend and reduce a logical volume in Logical volume management (LVM) also called as flexible volume file-system. Thaank you so much! ---

As this is you test cluster you can even burn it down 😛 But please be very careful and patient as doing this on your production cluster can cause lose of data. ---
