I am new to ELK and I am looking to setup a CentOS server with 500GB of disk space. I found the data structure on the site but I don't see anything on how the file system should be partitioned before I install. I'm assuming I need most of the space for the data partition? Do I need to adjust my partitions? ``` Filesystem Size Used Avail Use% Mounted on /dev/mapper/rootvg6-slash 11G 3.4G 6.6G 34% / tmpfs 4.2G 0 4.2G 0% /dev/shm /dev/sda1 500M 111M 363M 24% /boot /dev/mapper/rootvg6-home 2.1G 7.3M 2.0G 1% /home /dev/mapper/rootvg6-opt 11G 2.4M 10G 1% /opt /dev/mapper/rootvg6-tmp 2.1G 201M 1.8G 11% /tmp /dev/mapper/rootvg6-usr_local 1.1G 188M 783M 20% /usr/local /dev/mapper/rootvg6-var 11G 582M 9.4G 6% /var /dev/mapper/rootvg6-opt_IBM 4.1G 8.4M 3.9G 1% /opt/IBM /dev/mapper/rootvg6-opt_IBM_ITM 4.1G 290M 3.6G 8% /opt/IBM/ITM /dev/mapper/appvg-datalv 484G 74M 460G 1% /var/data /dev/mapper/appvg-loglv 11G 30M 9.9G 1% /var/log ``` ---

Assuming you're planning on configuring ES data directory to be somewhere under /var/data this partitioning looks reasonable. You'll want ample space for logs (a couple of gigabytes at least) which you also have. On a side note, I think your partitioning is a bit excessive. It's e.g. not obvious why /opt/IBM and /opt/IBM/ITM need to be different partitions. ---

It seems you are on RHEL 6 and confuse directories with volume groups / partitions. Just use the default partition scheme with two volume groups for `/` and `/home`, beside the system partitions for `/boot` and `/dev/shm` Having 30G assigned to root volume for OS upgrades, I run Elasticsearch with Elasticsearch user `es` in `/home/es` using the rest of the disk space of a 1.6T RAID1 array. There is no need to set up extra volume groups or partitions for `/opt`, `/tmp`, `/usr/local`, `/var`, `/opt/IBM`, `/opt/IBM/ITM`, `/var/data`, or `/var/log` - this will make admin life much more complicated. ---

Will it cause me a lot of pain later to configure the data store under /var/data? I see now on [this page](https://www.elastic.co/guide/en/elasticsearch/reference/1.7/setup-dir-layout.html) that the default data store when installing from rpm would be /var/lib/elasticsearch. I would like to be able to upgrade easily later when the time comes so it seems like using default paths would probably be best for that. Should I just move the space from /var/data to /var/lib? ---

> Will it cause me a lot of pain later to configure the data store under /var/data? I don't know the specifics of the RPM package and whether a package upgrade changes /etc/sysconfig/elasticsearch, but it probably doesn't. That's where you'll configure the data directory. So no, changing the data location shouldn't result in any problems. ---

Thanks for the help. I appreciate it. ---
