Repeat for any other shares that you have moved to the new hard drive. Verify these shares are accessible from another machine within your network.<'''NOTE:''' If any services depend on the location of a moved share, ensure they are configured to use the new share location. For example, if [https://www.amahi.org/apps/div>dlna DLNA] is installed, check the configuration file to verify it can find the new share location. Secondly, validate that that all such services start correctly and behave as expected. If the service doesn't start, it may be that it's looking for a specific share location during the service start up. ==Greyhole Storage Pool==Use new hard drive for [[Storage_pooling|Greyhole Storage Pool]].

That'The hard drive(s it. All your shares in /var/hda/files are now on your new ) and the mount point (path) should be listed for each hard driveadded. If not, then further investigation will be needed to determine the problem.<br />
=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 need to move your shares data, if any, into your new drive.<br/>[[Open Terminal as root|In a Terminal, as root]], type executing the following command. Replace to obtain the path in red with the path you received when you ran hda-diskmount. Replace '''something''' with the name of the share you want to have on your new UUID for each hard drive (the share should already exists).:
<div style="border: 1px solid #A3B1BF; padding: .5em 1em; color: #000; background-color: #E6F2FF; margin: 3px 3px 1em 3px;">
mv /var/hda/files/<strong>something</strong> <strong style="color:red">/var/hda/files/drives/sdb1/</strong> 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"
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.
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;">
umount /var/hda/files/drives/sdb1<br/> 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.
In nano, you'll need to add a new line at the bottom:EXAMPLE: # Mounting Greyhole Drives for Drive Pool. Take the line that # # 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-diskmount gave you (the blue one), and change the first value only.<br948e-ca46656507d2 /var/hda/files/drives/>drive2 ext4 defaults 1 2 # # Drive3 = WD-Charlie2TB in Microserver Bay 3 from left Instead of UUID=a7337504-376a-4d36-9f7a-1a24c0f55fbd /var/hda/devfiles/sdb1, enter '''drives/drive3 ext4 defaults 1 2 # # Drive4 = WD-Delta2TB in Microserver Bay 4 from left UUID=''' followed by the 8d881dcb-8de3-4621-b9bd-00025196868a /var/hda/files/drives/drive4 ext4 defaults 1 2 # # Drive5 = 250GB OS Drive mounted in Optical Drive bay UUID you found earlier.="4d6f8004-d190-4234-a03b-b68de988abf0 /var/hda/files/drives/drive5 ext4 defaults 1 2 # #
In nano, you:'''NOTE:''ll need to add a new line at ' Lines beginning with # are comments where the bottom. Take remainder of the line that hda-diskmount gave you (the blue one), and add it as-is:ignored
hda-diskmount gave meVerify 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;">
<strong style="color:blue">/dev/sdb1 /var/hda/files/drives/sdb1 ext4 defaults 1 2</strong> 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!
So I should add thisOnce 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;">
<strong>UUID=9d972abc-1639-44df-a60e-668618d40236</strong> /var/hda/files/drives/sdb1 ext4 defaults 1 2 reboot
</div>
Verify the hard drives have successfully mounted in the '''HDA Dashboard'''.
Save and exit nano If all drives mounted successfully, it should look something like this (CTRL-X, Y, ENTERUbuntu), and try your new mount:
:EXAMPLE:
[[File:Gstreet_greyhole_pool.png|options|caption]]
==Bad Blocks==
Optionally, you can test your new drive for bad blocks.<br/>
:'''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</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;">
mount e2fsck -a<brcn />ls /var/hda/files/drivesdev/'''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/
