These instructions At this point, partition and format the hard drive(s) if they are adapted from new. For hard drive(s) that contain data to be preserved, skip to the [[http://www.mjmwired.net/resources/mjm-fedora-f9.htmlAdding_a_second_hard_drive_to_your_HDA#ntfs hereMount|Mount]] step.
If you're planning to mount a NTFS disk, you'll need to make sure you have ntfs==Command-3gline (Fedora)==To partition the hard drive(s), fuse and fuse libs all installed. If notsubstitute sdX with hard drive device name, login such as root and run''sdb'':
[[Open Terminal as root|In a Terminal, as root]], execute the following:<blockquote><div style="border: 1px solid #A3B1BF; padding: .5em 1em; background-color: #E6F2FF; margin: 3px 3px 1em 3px;"> parted /dev/sdX</div></blockquote>Up to 2TB, at the ''(parted)'' prompt, enter:# mklabel msdos (answer ''yes'' if prompted)# mkpart primary 0% 100%# quit<br />Greater than 2TB, at the ''(parted)'' prompt, enter:# mklabel gpt (answer ''yes'' if prompted)# mkpart primary 0% 100%# quit<br />Verify the new partition was created:<div style="border: 1px solid #A3B1BF; padding: .5em 1em; background-color: #E6F2FF; margin: 3px 3px 1em 3px;"> ls -l /dev/disk/by-id/</div>:EXAMPLE: lrwxrwxrwx 1 root root 9 2010-02-18 03:24 ata-Hitachi_HDS722020ALA330_JK1131YAGDU37V -> ../../sda $ yum install fuse fuselrwxrwxrwx 1 root root 10 2010-02-18 03:24 ata-Hitachi_HDS722020ALA330_JK1131YAGDU37V-part1 -> ../../sda1 lrwxrwxrwx 1 root root 9 2010-02-18 03:24 ata-ST31000528AS_6VP08W65 -> ../../sdb <span style="color:#FF0000">'''lrwxrwxrwx 1 root root 9 2010-02-18 03:24 ata-ST31000528AS_6VP08W65-libs ntfspart1 -3g> ../../sdb1'''</span>
Then use fdisk to find the disk by running fdisk -l The new partition is named sdX1 (this is a lower case L not a 1)i.e. You may have to give the path (/sbinsdb1 in <span style="color:#FF0000">'''RED'''</fdiskspan>) to make it work.
Format the partition, execute (can substitute ext3):<blockquote><div style="border: 1px solid #A3B1BF; padding: .5em 1em; background-color: #E6F2FF; margin: $ 3px 3px 1em 3px;"> mkfs.ext4 -j /dev/sbinsdX1</fdisk -ldiv></blockquote>
This should return Repeat the needed information about all your disks. Look out [[Adding_a_second_hard_drive_to_your_HDA#Partition/Format|Partition/Format]] step for your newly attached diskeach hard drive to be partitioned and formatted. In my case in among the results I can find:
Disk /dev/sdb: 120.0GB 120034123776 bytes==GParted (Ubuntu)==255 headsFrom the HDA desktop (or using VNC), 63 sectors/track.... etc etc[[Open_Terminal_as_root|In a terminal as root]] and type '''gparted''' to launch the application.
I know my disk is 120GB so thatHere's the right onea general introduction on [http://www.youtube.com/watch?v=vdWkdrnNGRg YouTube]. This tells us the name Just use ''ext3'' or ''ext4'' instead of the new disk which is "sdb" in my case''fat32'' if you follow that tutorial. Running $ sudo /sbin/fdisk -lu /dev/sdb | grep NTFS
For drives > 2.0 TB, following these steps:* Choose hard disk in the dropdown menu (top right)* Select Device > Create Partition Table.will give you a break down of partitions. In my case, there. > Advanced > (Choose 'gpt's just one )* Create partition, sdb1, so this is the partition I will mount.
Now we can go on to create the mount points if needs be. But because my disk contains all my music, I want it to be mounted as if it were my local "Music" folder, so for me the mount point already exists. But if just want to access your disk easily you could just as easily mount it anywhere. Commonly mount points are put in either /mnt/ or /media/. It doesn't matter where - just be consistent when you are doing this.
To do this run these commands as root:
$ cd /mnt/
$ mkdir my_ntfs_disk
Substituting my_ntfs_disk for whatever you want to call it:<b>NOTE:</b> [http://gparted.org GParted] supports GUID-partitioned drives, however, the hda-mount script do not support currently.
Now we can mount Repeat the disk in the desired location. Again as root run this command: $ mount [[Adding_a_second_hard_drive_to_your_HDA#Partition/devFormat|Partition/sdb1 /mnt/my_ntfs_drive -t ntfs-3g -r -o umask=0222Format]] step for each hard drive to be partitioned and formatted.
This command will make =Mount=Mount the mounted hard drive read only. That'(s great if that')/partition(s what you want, but ) for me, since I want to save my music there, I need it to be read and writeableuse in the HDA. For this you'll use:
:'''NOTE:''' $ mount /dev/sdb1 /mnt/my_ntfs_drive If you prefer not to use ''hda-t ntfsdiskmount'', refer to [[Adding_a_second_hard_drive_to_your_HDA#hda-3g diskmount|Troubleshooting ''hda-rw -o umask=0000diskmount]].
or in my case[[Open Terminal as root|In a Terminal, as root]], execute the following(it will create drive1, drive2, etc and mount the hard drive(s) automatically):<div style="border: 1px solid #A3B1BF; padding: .5em 1em; background-color: #E6F2FF; margin: 3px 3px 1em 3px;"> hda-diskmount</div>

because I want it mounted The line in my <span style="Musiccolor:#0000FF" file>'''BLUE'''</span> is what you need to copy and add to the bottom of ''/etc/fstab''. This is '''REQUIRED''' for the hard drive(s) to be permanently mounted.
Remember in both of these commands There will be multiple lines for multiple hard drive(s) added. Ensure youcopy and add '''ONLY'''ll need to substitute sdb1 with whatever those which were not present in the partition name/number is on your machine''before. And in the second command USERNAME is your linux usernametxt'' file.
If you now go to your desktopThe new hard drive storage space can be used for [[Adding_a_second_hard_drive_to_your_HDA#All Shares|All Shares]], [[Adding_a_second_hard_drive_to_your_HDA#Some Shares|Some Shares]], you should see or the drive is mounted there[[Adding_a_second_hard_drive_to_your_HDA#Greyhole Storage Pool|Greyhole Storage Pool]]. Click Follow the guidance below based on it to see the contents are there. If you've mounted it as say So far so good? Ok, let's continuedesired usage for each hard drive.
What you==All Shares==Host 've achieved so far is a temporary mounting of ''ALL''' shares on the new hard drive/partition. That shows it can be done but you'll need to make it permanent otherwise when you reboot it'll disappear again. For this you need to edit fstab with your favourite text editor. As root run:
$ gedit Move all the shares data to the new drive, replacing path in '''<span style="color: red;">RED</etcspan>''' with the path from the ''hda-diskmount'' output line in <span style="color:#0000FF">'''BLUE'''</fstabspan>.<br />

Easiest to cut and paste UUID's straight from the terminal. Edit ''/etc/fstab'' to mount each drive:<div style="border: 1px solid #A3B1BF; padding: .5em 1em; color: #000; background-color: #E6F2FF; margin: 3px 3px 1em 3px;"> nano /etc/fstab</div>Then '''very carefully''' add the following line for each disk into the end of the fstab file. Ensure correct UUID, hard drive number and hard drive file system (ext4 in this case) are added.  :EXAMPLE: UUID=55d9333f-d801-425a-b2af-d65c5966d56f /var/hda/files/drives/drive1 ext4 defaults 1 2 It should look something like the following when lines are added for each of the five drives in this example.  :EXAMPLE: # Mounting Greyhole Drives for Drive Pool.net # # Drive1 = Seagate-Alpha2TB in Microserver Bay 1 from left UUID=55d9333f-d801-425a-b2af-d65c5966d56f /resourcesvar/mjmhda/files/drives/drive1 ext4 defaults 1 2 # # Drive2 = Seagate-fedoraBeta2TB in Microserver Bay 2 from left UUID=5bd5498f-f930c1-4780-948e-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;"> mount -a</div>If there are errors,most likely a line was not added properly.

Recommend starting it in the evening so it will be completed the next day. [[Open Terminal as root|In a Terminal, as root]], execute following command (replace '''sdb1''' with the (<strong style="color:blue">BLUE</strong>) value you received from ''hda-diskmount''):<div style="border: 1px solid #A3B1BF; padding: .5em 1em; color: #000; background-color: #E6F2FF; margin: 3px 3px 1em 3px;"> e2fsck -cn /dev/'''sdb1'''</div>You'll receive a message stating '''WARNING!!!''' ''Running e2fsck on a mounted filesystem may cause SEVERE filesystem damage. Do you really want to continue (y/n)?''<br/> Answer ''yes''. The <code>-cn</code> option we're using can safely be used on mounted file systems.==Spin Down Hard Drives== Low power is a good thing to have in servers. If you do not use your server very often, you may want to force the hard drives to spin down faster than the default. Here is how. First ensure ''hdparm'' package is installed: sudo dnf install hdparm To force to spin down after 10 minutes of being idle, add these lines to <code>/etc/rc.local</code>:<pre># power drives down after 10 minutes idle/sbin/hdparm -S120 /dev/sda/sbin/hdparm -S120 /dev/sdb...</pre> Most drives will power down on their own without doing this. Once stopped, the drive may take as long as 30 seconds to respond to a 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": the device will not automatically enter standby mode. 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 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 have very different interpretations of these values. It may make the system run cooler and power efficient (especially on a Home Server you are rarely using all of the pool drives at the same time). =Troubleshooting===hda-diskmount==If ''hda-diskmount'' does not mount the hard drive or you prefer to do it manually, complete the following steps: 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; background-color: #E6F2FF; margin: 3px 3px 1em 3px;"> mkdir -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)<blockquote><div style="border: 1px solid #A3B1BF; padding: .5em 1em; background-color: #E6F2FF; margin: 3px 3px 1em 3px;"> ls -l /dev/disk/by-uuid/</div></blockquote> :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-89af-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; 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-a8d48ec2bc82 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'''</span> :The new entry will be mounted as ''/var/hda/files/drives/drive1'' (i.e. sdb1 in '''<span style="color:#0000FF">BLUE</span>''') Mount the hard drive<blockquote><div style="border: 1px solid #A3B1BF; padding: .5em 1em; background-color: #E6F2FF; margin: 3px 3px 1em 3px;"> mount -a</div></blockquote>:If all goes well, there should not be any output.
