Now we can go on to create ==GParted (Ubuntu)==From the mount points if needs be. But because my disk contains all my musicHDA desktop (or using VNC), I want it [[Open_Terminal_as_root|In a terminal as root]] and type '''gparted''' to be mounted as if it were my local "Music" folder, so for me launch the mount point already exists. But if just want to access your disk easily you could just as easily mount it anywhereapplication. 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 Here's a general introduction on [http://www.youtube.com/watch?v=vdWkdrnNGRg YouTube]. Just use ''ext3'' or ''ext4'' instead of ''fat32'' if you want to call itfollow that tutorial.
Now we can mount the For drives > 2.0 TB, following these steps:* Choose hard disk in the desired locationdropdown menu (top right)* Select Device > Create Partition Table... Again as root run this command:> Advanced > (Choose 'gpt') $ mount /dev/sdb1 /mnt/my_ntfs_drive -t ntfs-3g -r -o umask=0222* Create partition
This command will make the mounted drive read only. That's great if that's what you want, but for me, since I want to save my music there, I need it to be read and writeable. For this you'll use:
:<b>NOTE:</b> $ mount /dev[http:/sdb1 /mnt/my_ntfs_drive gparted.org GParted] supports GUID-t ntfspartitioned drives, however, the hda-3g -rw -o umask=0000mount script do not support currently.
or in my caseRepeat the [[Adding_a_second_hard_drive_to_your_HDA#Partition/Format|Partition/Format]] step for each hard drive to be partitioned and formatted.
$ mount /dev=Mount=Mount the hard drive(s)/sdb1 /home/USERNAME/Music -t ntfs-3g -rw -o umask=0000partition(s) for use in the HDA.

[[Open Terminal as root|In a Terminal, as root]], executing the following command to obtain the UUID for each hard drive:<div style="border: 1px solid #A3B1BF; padding: .5em 1em; color: #000; background-color: #E6F2FF; margin: 3px 3px 1em 3px;"> blkid</div>:EXAMPLE: /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" In this case, there are four data drives (sda1, sdb1, sdc1, sdd1) and the Operating system assigned to a fifth drive, sde. Take note of the UUID's for each drive. 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. # # 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;"> mount -a</div>If there are errors,most likely a line was not added properly. If this is not corrected, the machine may not boot and hang trying to mount the hard drives! Once there are no errors, reboot machine:<div style="border: 1px solid #A3B1BF; padding: .5em 1em; color: #000; background-color: #E6F2FF; margin: 3px 3px 1em 3px;"> reboot</div>Verify the hard drives have successfully mounted in the '''HDA Dashboard'''. If all drives mounted successfully, it should look something like this (Ubuntu): :EXAMPLE:[[File:Gstreet_greyhole_pool.png|options|caption]] ==Bad Blocks==Optionally, you can test your new drive for bad blocks.net<br/resources> :'''NOTE:''' This can take a ''long'' time to complete! 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</mjmstrong>) value you received from ''hda-fedoradiskmount''):<div style="border: 1px solid #A3B1BF; padding: .5em 1em; color: #000; background-f9color: #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.
