=Tips==Use the hard drive for only some shares=Mount Order==If you want only some of your shares The following guide will outline how to be manually order hard drives and mount them automatically on your new hard drive, here's how to do thatboot.

First, you'll want to move your previous shares data, if any, into your new drive.<br/>You only need to do this next command if you have data that you care about in the /var/hda/files/* folders (that you want on the new drive).<br/>[[Open Terminal as root|In a Terminal, as root]], type executing the following command. Replace the path in red with the path you received when you ran hda-diskmount2. Replace '''something''' with the name of to obtain the share you want to have on your new UUID for each hard drive (the share should already exists).:

Repeat with every share you want on your new In this case, there are four data drives (sda1, sdb1, sdc1, sdd1) and the Operating system assigned to a fifth drive, sde.

Next, youTake note of the UUID'll need s for each drive. Easiest to make cut and paste UUID's straight from the mount permanentterminal.

umount /var/hda/files/drives/sdb1<br/> nano /etc/fstab

In nano, you'll need to add a new line at the bottom. Take the line that :EXAMPLE: UUID=55d9333f-d801-425a-b2af-d65c5966d56f /var/hda-diskmount2 gave you, and insert that.<br/>files/drives/drive1 ext4 defaults 1 2

So, It should look something like the following previous examples, I should add when lines are added for each of the five drives in this:example.

:EXAMPLE: # Mounting Greyhole Drives for Drive Pool. # # Drive1 = Seagate-Alpha2TB in Microserver Bay 1 from left UUID=55d9333f-d801-425a-b2af-d65c5966d56f /var/hda/files/drives/drive1 ext4 defaults 1 2 # # Drive2 = Seagate-Beta2TB in Microserver Bay 2 from left UUID=5bd5498f-30c1-4780-948e-ca46656507d2 /var/hda/files/drives/drive2 ext4 defaults 1 2 # # Drive3 = WD-Charlie2TB in Microserver Bay 3 from left UUID=a7337504-376a-4d36-9f7a-1a24c0f55fbd /var/hda/files/drives/drive3 ext4 defaults 1 2 # # Drive4 = WD-Delta2TB in Microserver Bay 4 from left UUID=8d881dcb-8de3-4621-b9bd-00025196868a /var/hda/files/drives/drive4 ext4 defaults 1 2 # # Drive5 = 250GB OS Drive mounted in Optical Drive bay UUID="4d6f8004-d190-4234-a03b-b68de988abf0 /var/hda/files/drives/drive5 ext4 defaults 1 2 # # :'''NOTE:''' Lines beginning with # are comments where the remainder of the line is ignored  Verify there are no issues by executing the following:<div style="border: 1px solid #A3B1BF; padding: .5em 1em; color: #000; background-color: #E6F2FF; margin: 3px 3px 1em 3px; text-align: left;"><span style="color: blue;">UUID=9d972abc-1639-44df-a60e mount -668618d40236 /var/hda/files/drives/sdb1 ext4 defaults 1 2</span>a

Save and exit nano (CTRL-XOnce there are no errors, Y, ENTER), and try your new mountreboot machine: 

That last command If all drives mounted successfully, it should show you the content of you new hard drive.look something like this (Ubuntu):

That's it. Your share(s) are now on your new hard drive:EXAMPLE:[[File:Gstreet_greyhole_pool.png|options|caption]]

===Use the hard drive in your Greyhole storage pool=Bad Blocks==If Optionally, you want to add can test your new hard drive to your Greyhole storage pool, here's how to do thatfor bad blocks.<br/>

First, you:'''NOTE:''' This can take a ''long''ll need time to make complete! Recommend starting it in the evening so it will be completed the mount permanentnext day. [[Open Terminal as root|In a Terminal, as root]], type the following command:

umount e2fsck -cn /var/hda/files/drivesdev/'''sdb1<br/>nano /etc/fstab'''

In nano, It may make the system run cooler and power efficient (especially on a Home Server you'll need to add a new line are rarely using all of the pool drives at the bottom. Take the line that hda-diskmount2 gave you, and insert thatsame time).<br/>

So=Troubleshooting===hda-diskmount==If ''hda-diskmount'' does not mount the hard drive or you prefer to do it manually, complete the following previous examples, I should add thissteps:

Create the mount point (choose one '''NOT''' in use) [[Open Terminal as root|in a Terminal, as root]] by executing the following:<blockquote><div style="border: 1px solid #A3B1BF; padding: .5em 1em; color: #000; background-color: #E6F2FF; margin: 3px 3px 1em 3px; text"> mkdir -align: left;"p /var/hda/files/drives/drive1</div></blockquote>Identify the hard drive to mount and copy the UUID from the output that corresponds to the hard drive (i.e. sdb)<span blockquote><div style="border: 1px solid #A3B1BF; padding: .5em 1em; background-color: blue#E6F2FF; margin: 3px 3px 1em 3px;">UUID=9d972abc ls -1639-44df-a60e-668618d40236 l /vardev/hdadisk/filesby-uuid/drives/sdb1 ext4 defaults 1 2</spandiv></divblockquote>

Save and exit nano (CTRL:EXAMPLE: lrwxrwxrwx 1 root root 10 Dec 29 18:10 1b8597e0-5d95-4474-b093-53099c8c81c9 -> ../../sda1 lrwxrwxrwx 1 root root 10 Dec 29 18:10 1c161033-c695-4291-aba1-257d3987edf7 -> ../../dm-0 lrwxrwxrwx 1 root root 10 Dec 29 18:10 b7017251-cb54-438b-92a3-781537c565e6 -> ../../sdb lrwxrwxrwx 1 root root 10 Dec 29 18:10 c1fe62b3-41dc-4a67-8a6b-09f90b7893ba -> ../../dm-1 lrwxrwxrwx 1 root root 10 Dec 29 18:10 e0f5a9bd-f52b-431e-X, Y, ENTER), and try your new mount89af-61da70659bdd -> ../../dm-2 lrwxrwxrwx 1 root root 10 Dec 29 18:10 <span style="color:#FF0000">'''547b073d-e591-4913-b4fb-7c5084353979'''</span> -> ../../sdb1

:The UUID for sdX1 (i.e. sdb1 is <span style="color:#FF0000">'''RED'''</span>).Add the following to the end of ''/etc/fstab'', replacing the UUID as captured in the previous step<blockquote><div style="border: 1px solid #A3B1BF; padding: .5em 1em; color: #000; background-color: #E6F2FF; margin: 3px 3px 1em 3px;"> nano /etc/fstab</div></blockquote>:EXAMPLE: # # /etc/fstab # Created by anaconda on Sat Nov 9 01:46:39 2013 # # Accessible filesystems, by reference, are maintained under '/dev/disk' # See man pages fstab(5), findfs(8), mount (8) and/or blkid(8) for more info # UUID=1ebbf241-528c-465e-889f-acc15400dd8c / ext4 defaults 1 1 UUID=087b15a5-c3ca-4615-b6ee-bf5f399a803e /boot ext4 defaults 1 2 UUID=75346b8e-b162-458c-b0e9-aa8d48ec2bc82 swap swap defaults 0 0 UUID=ad85eeb9-18f0-4b85-9bfa-b88a5d1489b3 swap swap defaults 0 0 <span style="color:#0000FF">'''UUID=547b073d-e591-4913-b4fb-7c5084353979 /var/hda/files/drives/drive1 ext4 defaults 1 2'''</divspan>

Finally, you:The new entry will be mounted as ''/var/hda/files/drives/drive1''ll need to configure Greyhole to select your new partition(i.e.sdb1 in '''<span style="color:#0000FF">BLUE</span>''')

In Mount the [httphard drive<blockquote><div style="border:1px solid #A3B1BF; padding: .5em 1em; background-color: #E6F2FF; margin: 3px 3px 1em 3px;"> mount -a</div></hda/setup?sub=disk_pooling&tab=share Shares &gt; Storage Pool page] of your Amahi dashboard, you'll see a list of mounted partitionsblockquote>:If all goes well, with checkboxes next to eachthere should not be any output. If there are errors, allowing you to include those partitions in your storage poolstop and diagnose the problem.

You should now have a new row in there, referring to Accomplish [[Adding_Hard_Drives_101#Verify/varTest|Verify/hda/files/drives/sdb1Test]] step to ensure the hard drive is properly mounted.<br/>Select it (click the checkbox).

That's it. Your new Repeat this process for each hard drive just increased your Greyhole storage pool capacityto be mounted.
