Mission Control: Operation Mountpoint

mount - a hands-on Linux lab on a real virtual machine.

The RHCSA file-systems capstone on a real RHEL 10 machine. Wire local XFS by UUID, an NFS mount, an autofs automount, an SGID share, and a permission fix, graded on live end-state. Mission mode.

You have finished the File Systems module. Now you wire a real RHEL 10 machine for storage and sharing: a fresh local filesystem, a mount from a server, an on-demand automount, a shared team directory, and a permission problem to solve. This is the everyday work of keeping a server's storage in order, and every piece is graded on the live result.

Five objectives, one real machine with a blank spare disk (vdb) and a file server on the network (content.lab.example.net). Everything you set must survive a reboot.

This is mission mode. No commands are shown. You read the objective, recall the tool, and wire the mount. You will need root, so reach for sudo. Progress checks itself against the live mounts.

One quick rep before you start. Before you mount anything new, you look at what is already mounted. Ask what filesystem is mounted at the root of the tree.

prompt: [root@servera ~]# answer: findmnt / output: TARGET SOURCE FSTYPE OPTIONS / /dev/mapper/rhel-root xfs rw,relatime,seclabel,attr2,inode64,logbufs=8,logbsize=32k,noquota hint: findmnt with a path shows exactly what is mounted there: the source device, the filesystem type, and the options. findmnt /

That is the tool you will use to check every objective: findmnt tells you the truth about what is mounted where. Now wire the machine.

Boot the machine below and take the console. Read ~/MOUNTPOINT.txt for the checklist. Five objectives: a local XFS filesystem at /data by UUID, an NFS mount from the server at /mnt/nfs, an autofs automount at /mnt/auto/share, an SGID team folder at /srv/team, and a blocked user to unblock. Work as root, and make it persistent.

Practice Mission Control: Operation Mountpoint in a real Linux terminal at The Linux Camp. Progress is verified automatically as you type commands on the machine.
