I have a local disk (raid10) I mounted for storage in CentOS 7. From reading
I believe there is no reason to put LVM on top and I can just partition and
mount. So I figured I mount the filesystem directly on the partition. 

 

/etc/fstab, like:

/dev/sdb1  /mydata  xfs defaults,noatime 0 0

 

This all worked fine and seems fine after reboot, but I got worried.  This
is not something I've done before since my experience is with big databases,
thus I have only worked with mounting external LUNs from storage devices. On
those I always use multipath and udev to associate them to the disks because
the /dev/<dev> names can change on reboot.


Is this not true with local drives?  i.e. will the local drives always mount
with the same name, thus my /etc/fstab above is valid?

 

Thank you for your help,

 

Jed
