Exercise 3: Disk Management - Managing Advanced Storage
Here are some key issues pertaining to Managing Advanced Storage that have been addressed and are crucial for exam preparation.
Managing Advanced Storage
Create a Stratis pool named pisstratispool using the disk /dev/nvme0n5.

Expand capacity of the pisstratispool using the another disk /dev/nvme0n6.
[root@server ~]# stratis pool add-data pisstratispool /dev/nvme0n6 [root@server ~]# stratis pool list Name Total / Used / Free Properties UUID Alerts pisstratispool 7 GiB / 530 MiB / 6.48 GiB ~Ca,~Cr, Op e90237bc-e62d-46d5-9001-618b9dc6ff8e
Create a thin provisioned filesystem named pispoolfs in the pisstratispool
[root@server ~]# stratis fs create pisstratispool pispoolfs [root@server ~]# stratis fs list Pool Filesystem Total / Used / Free / Limit Created Device UUID pisstratispool pispoolfs 1 TiB / 546 MiB / 1023.47 GiB / None Apr 16 2024 16:02 /dev/stratis/pisstratispool/pispoolfs cfbebc79-8c84-4955-9111-fed84d3d56bb
Mount the pispoolfs filesystem on /pisdir4 directory and also make sure that it gets mounts automatically at boot time.
