Trying to wrap my head around this stuff... A few questions

Postby diggityDawg » Thu Mar 21, 2013 5:33 pm

I've been using Amahi for about a week now, and things are starting to make sense to me, but I'm still struggling with the whole storage thing. If someone could enlighten me I'd really appreciate it! I should say first that I moved from Windows Home Server, so all of the drives I have are, or were, ntfs formatted.

First of all, I've got is a machine with 4 drives in it. One drive is a 2TB drive partitioned into 4 drives and mounted as /, /home, swap, and a large partition for data. Then I have 3 other drives that are, or were originally, Windows drives. I also have a 5-drive eSata enclosure connected to this machine. So in all, I've got 9 drives going here. My strategy was to move the data from one drive, reformat it as ext4 (is there a reason to use ext3 instead?), add it to greyhole and then fill it up with data, allowing me to move another drive over, etc., etc. What I'm struggling with are several things:
  • 1. I mentioned it above, but is there a reason I should use ext3 instead of ext4 formatting?
    2. How do I identify which drives are internal and which are external from within the file manager?
    3. In my attempt to move the drives from /media to /mnt, I've completely messed up both of those folders. What is the guidance on how to properly move mount points? Should I just copy all of the data from the ntfs drives first, and then move them into mnt? And what is the guidance on how to label them, or what folder I should use in /mnt for each drive?
    4. I've create shares in Amahi, which are all pointing to folders under my /home/username/ folder (i.e. /home/username/Movies, /home/username/Music, etc). I've set them all to Use Pool. Will they use the Greyhole pool, or do I need to move the shares to one of the Greyhole drives?
    5. How do I find out how much free space I have in my pool?
    6. Every time I boot up I get errors saying this drive or that drive can't be mounted, or isn't available yet, etc. I've put them all into fstab, and once I boot up they are all there, so why aren't they available during boot?
    7. Almost forgot this one - in my Storage Pool screen in Amahi I see these warning icons (Image) and I have no idea what the actual warning is. How do I find that out? It's not clickable, and when you mouse over it it just says "WARNING"...
As you can see, I'm a little lost. Any help or clear guidance you can point me to is very appreciated. I don't mind reading to learn about this stuff, but there's SO much info out there, I'm not sure what actually pertains to me and what doesn't...

Thanks!
Eddie

1. I mentioned it above, but is there a reason I should use ext3 instead of ext4 formatting?
Not really. All my drives are ext4. For security sake, you will benefit from ext4.

2. How do I identify which drives are internal and which are external from within the file manager?
what file manager? if you're talking about the Amahi dashboard, you will see all your drives there as ordered indicated partitions such as...
/dev/sda1, /dev/sda2, /dev/sda3, /dev/sdb1, /dev/sdb2. etc...

You can setup any shared folder structure you like from the dashboard. If you're using greyhole storage pooling, you needn't really concern with what's going on what drive. Maybe this needs a more specific question


3. In my attempt to move the drives from /media to /mnt, I've completely messed up both of those folders. What is the guidance on how to properly move mount points? Should I just copy all of the data from the ntfs drives first, and then move them into mnt? And what is the guidance on how to label them, or what folder I should use in /mnt for each drive?

here's some threads/ wiki articles that have drive management content. There's a lot covering this stuff in the forum as well as online. I feel it best to understand how linux manages mounted volumes/partitions before wrapping your head around how Amahi works with your shares.

A number of people, just like you have made the migration from Windows :D


4. I've create shares in Amahi, which are all pointing to folders under my /home/username/ folder (i.e. /home/username/Movies, /home/username/Music, etc). I've set them all to Use Pool. Will they use the Greyhole pool, or do I need to move the shares to one of the Greyhole drives?

Using the home directory is more of a fallback for Amahi when it tries to find shares on install, but finds none. You will want to use the guidance above to move those folders out of the /home/ folder soon because the /home folder will fill up quickly. Typically you will move these to /var/hda/files/Music (etc)

5. How do I find out how much free space I have in my pool?

Once you've moved everything to the appropriate drives/folders/pools, the Amahi Dashboard will show you everything

6. Every time I boot up I get errors saying this drive or that drive can't be mounted, or isn't available yet, etc. I've put them all into fstab, and once I boot up they are all there, so why aren't they available during boot?
This could be caused by some confusion or mis-handling of the drives and their /etc/fstab entries

7. Almost forgot this one - in my Storage Pool screen in Amahi I see these warning icons (Image) and I have no idea what the actual warning is. How do I find that out? It's not clickable, and when you mouse over it it just says "WARNING"...

see the answer to 3, 4 and 5 :D

Thanks for the detailed response! I have begun reading those posts and will post any other questions I have if I need more help, but I think this should get me on my way.

Thanks again!
