The following guide will outline how to manually order your disks hard drives and mount drives them automatically on boot.

1. First[[Open Terminal as root|In a Terminal, as root]], get executing the following command to obtain the UUID for each hard drive by opening a terminal and entering command :<div style="border: 1px solid #A3B1BF; padding: .5em 1em; color: #000; background-color: #E6F2FF; margin: 3px 3px 1em 3px;"> blkid<pre/div>gstreet@gstreet-MicroServer:~$ sudo blkid[sudo] password for gstreetEXAMPLE: /dev/sda1: LABEL="Seagate-Alpha2TB" UUID="55d9333f-d801-425a-b2af-d65c5966d56f" TYPE="ext4" /dev/sdb1: LABEL="Seagate-Beta2TB" UUID="5bd5498f-30c1-4780-948e-ca46656507d2" TYPE="ext4" /dev/sdc1: LABEL="WD-Charlie2TB" UUID="a7337504-376a-4d36-9f7a-1a24c0f55fbd" TYPE="ext4" /dev/sdd1: LABEL="WD-Delta2TB" UUID="8d881dcb-8de3-4621-b9bd-00025196868a" TYPE="ext4" /dev/sde1: LABEL="root" UUID="4d6f8004-d190-4234-a03b-b68de988abf0" TYPE="ext4" /dev/sde3: LABEL="home" UUID="d0531fa1-9311-4d53-b838-f35898adbd98" TYPE="ext4" /dev/sde5: LABEL="swap" UUID="3c39206c-ba60-47ff-a1fe-f5821b2ab543" TYPE="swap"</pre></div> In this case, the user has four data drives (sda1, sdb1, sdc1, sdd1) and the Operating system assigned to a fifth drive, sde.

Take note of In this case, there are four data drives (sda1, sdb1, sdc1, sdd1) and the UUID's for each Operating system assigned to a fifth drive, sde. Easiest to cut and paste UUID's straight from the terminal - no typo's!

2. Then edit /etc/fstab to mount Take note of the UUID's for each drive - for novices, easiest to do this using a graphical editor. You might consider first making a copy called fstab.bak (use the "save as" command, close file Easiest to cut and then gedit the original fstab again) so that you can recover paste UUID's straight from the original fstab file if you make mistakesterminal.

sudo nano /etc/fstab

3. :EXAMPLE: Then '''very carefully''' add the following line for each disk into the end of the fstab file. Make sure you paste in the right UUID, drive number and drive file system (=55d9333f-d801-425a-b2af-d65c5966d56f /var/hda/files/drives/drive1 ext4 in this case). defaults 1 2

Note that the hda-diskmount command had already added lines to mount my OS drive which had two partitions (root or /, and home). Save file and close. 4. Save file and reboot machine.  5. Check that drives have successfully mounted in Amahi hda (Setup - Shares - Storage Pool) In this case, if If all drives mounted successfully, it should look something like this (Ubuntu):

[[Open Terminal as root|In a Terminal, as root]], type the execute following command. Replace (replace '''sdb1''' with the (<strong style="color:greenblue">sdb1BLUE</strong> with the (green) value you received from ''hda-diskmount.''):

e2fsck -cn /dev/<strong style="color:green">'''sdb1</strong>'''

You'll receive Once stopped, the drive may take as long as 30 seconds to respond to a warning that says subsequent disk access, though most drives are much quicker. The encoding of the -S timeout value is somewhat peculiar. A value of zero means "timeouts are disabled"WARNING!!! : the device will not automatically enter standby mode. Running e2fsck on Values from 1 to 240 specify multiples of 5 seconds, yielding timeouts from 5 seconds to 20 minutes. Values from 241 to 251 specify from 1 to 11 units of 30 minutes, yielding timeouts from 30 minutes to 5.5 hours. A value of 252 signifies a timeout of 21 minutes. A value of 253 sets a mounted filesystem vendor-defined timeout period between 8 and 12 hours, and the value 254 is reserved. 255 is interpreted as 21 minutes plus 15 seconds. Note that some older drives may cause SEVERE filesystem damage have very different interpretations of these values. Do  It may make the system run cooler and power efficient (especially on a Home Server you really want to continue (y/nare rarely using all of the pool drives at the same time)?"<br/>Answer ''yes''. The -cn option we're using can safely be used on mounted filesystems.
