forest@ubuntu:~$ sudo mkdir /media/raiddisk

forest@ubuntu:~$ sudo mount -v /dev/md1 /media/raiddisk
mount: you didn't specify a filesystem type for /dev/md1
I will try all types mentioned in /etc/filesystems or /proc/filesystems
Trying ext3
Trying ext2
Trying ext4
Trying fuseblk
mount: you must specify the filesystem type
forest@ubuntu:~$ sudo mount -v xfs /dev/md1 /media/raiddisk
[sudo] password for forest:
Usage: mount -V : print version
mount -h : print this help
mount : list mounted filesystems
mount -l : idem, including volume labels
So far the informational part. Next the mounting.
The command is `mount [-t fstype] something somewhere'.
Details found in /etc/fstab may be omitted.
mount -a [-t|-O] ... : mount all stuff from /etc/fstab
mount device : mount device at the known place
mount directory : mount known device here
mount -t type dev dir : ordinary mount command
Note that one does not really mount a device, one mounts
a filesystem (of the given type) found on the device.
One can also mount an already visible directory tree elsewhere:
mount --bind olddir newdir
or move a subtree:
mount --move olddir newdir
One can change the type of mount containing the directory dir:
mount --make-shared dir
mount --make-slave dir
mount --make-private dir
mount --make-unbindable dir
One can change the type of all the mounts in a mount subtree
containing the directory dir:
mount --make-rshared dir
mount --make-rslave dir
mount --make-rprivate dir
mount --make-runbindable dir
A device can be given by name, say /dev/hda1 or /dev/cdrom,
or by label, using -L label or by uuid, using -U uuid .
Other options: [-nfFrsvw] [-o options] [-p passwdfd].
For many more details, say man 8 mount .
forest@ubuntu:~$ sudo mount -t xfs /dev/md1 /media/raiddisk
mount: wrong fs type, bad option, bad superblock on /dev/md1,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so
