How to Create a File System on a Metadevice (Command Line)
After checking the prerequisites ("Prerequisites for Creating DiskSuite Objects"), and the preliminary information ("Preliminary Information for Creating File Systems on Metadevices"), use the newfs(1M) command to create a new file system on a metadevice. Refer to the newfs(1M) man page for more information.

This example creates a file system on a concatenation named d3. The fsck(1M) command verifies the new file system.

This example creates a file system on a concatenation name d33 in diskset relo-red.
Note -
A file system that resides on a metadevice in a diskset cannot be automatically mounted at boot via the /etc/vfstab file. The necessary diskset RPC daemons (rpc.metad and rpc.metamhd) do not start early enough in the boot process to permit this. Additionally, the ownership of a diskset is lost during a reboot.
Where to Go From Here
|
If You Want to Make the File System Available ... |
Then ... |
|---|---|
|
Now |
Mount the file system with the mount(1M) command, specifying the metadevice name as the mount device, such as /dev/md/dsk/d30. |
|
Automatically when the system boots |
Create or modify the file system's entry in /etc/vfstab file, using the metadevice block and raw device names. |
