=====Using Stratis=====

Stratis is a service that needs to be installed and enabled.

To manage file systems with the Stratis storage management solution, install the stratis-cli and stratisd packages.

<code> dnf install stratis-cli stratisd
systemctl enable --now stratisd
</code>

====Process to add storage using Stratis====

  * check stratis pools <code> stratis pool list </code>
  * Create a stratis pool of one or more block devices  <code> stratis pool create pool1 /dev/vdb </code>
  * You can add more devices using the add data option <code>stratis pool add-data pool1 /dev/vdc</code>
  * create file systems from a pool  <code> stratis filesystem create pool1 fs1 </code>
  * you can create snaphots of of file systems using  <code> stratis filesystem snapshot pool1 fs1 snapshot1 </code>
  * You can add the stratis file systems to fstab to permanently mount get UUID using <code> lsblk --output=UUID /dev/stratis/pool1/fs1
  or
  stratis filesystem list </code>
  
to add them to fstab you need to use the options
<code>UUID=c7b57190-8fba-463e-8ec8-29c80703d45e /dir1 xfs defaults,x-systemd.requires=stratisd.service 0 0</code>

ensure **x-systemd.requires=stratisd.service ** is in fstab

====Checking stratis====

to see what block devices are in a pool use
<code> stratis blockdevlist pool-name </code>

to check the filesystems in stratis
<code> stratis filesystem list </code>

===to mount Stratis filesystems===

use the UUID in fstab  or to manually mount them use
<code>[root@servera ~]# mount /dev/stratis/poolname/filesystem-name /mountpoint </code>

To remove files systems or snapshots use command
<code> [root@servera ~]# stratis filesystem destroy poolname filesystem-name</code>

====Issues====

not entering details correctly in fstab will cause it to abort to emergency target

**df** will always tell you the size is 1Tb to get accurate size and usage use **stratis pool list**
