    Chrome OS

    I'm researching this too.  It seems like the CloudReady build of Chrome OS has value add above the base open source images Google provides but isn't the full blown version Google built for chromebooks.  This thread might be of interest: 

     

    (SOLVED, dumb) early in setup, swapping out cache drive- wiki seems backassward

    (SOLVED)

    I currently have an old 64gb SSD + 128 GB SSD set as a cache pool.  I watched a few space invader One videos and realized I'd be better off dedicating a 500 GB SSD to the cause.  I figured that turning off the cache on all shares then initiating the mover would theoretically make it easy to swap drives but the documentation/ wiki says the opposite of what I expected:

    Replace A Cache Drive
     

    Click on Shares and set all shares present on your Cache disk to Use cache disk: Yes. This will cause the Mover to move all shares OFF the Cache drive!

     Wouldn't setting all the shares to Use cache disk: NO cause the mover to clear off the cache drives?

     

    I've been known to be wrong often so ¯\_(ツ)_/¯

    100% CPU in dashboard, 15% in HTOP

    in General Support

    I asked almost the exact question yesterday but was using top instead of htop.  The response on /r/unraid was "Top does not include IOWAIT while dashboard does.  You can always Install netdata where you can see this type of data."

     

    I personally think the CPU data in the dashboard is misleading but I'm a total noob so I might just be dumb.

    ratio of storage : cache : parity & best allocation for my available drives

    fixed trurl's handle

    Thanks trurl!

     

    I have much more reading to do for sure!

     

    I've been reading up on the "unlimited" GDrive space for 5+ users for $10/month.  I might just let them manage my remote backup needs and use Rclone or nextcloud (lots of reading there too) to backup.  I likely don't need more than a couple of gigs of backup anyway and don't need versioning so I need to rethink if it makes sense to have the 8tb as backup, if I should use a smaller drive, or if I should use gdrive (or some combo).

     

    If I do shuck the other 8TB, you suggest going with RAID1/ mirror on the 2x 8TB as Parity?  Would I do this using the raid ability of my mobo or via software (I'm a noob). 

    Nothing in my setup would be super time sensitive as far as needing a quick recovery.  Kids could watch netflix and other streaming services if plex is dead for a week.

    The best way in my opinion is to just use the default raid1, that way you get redundancy. It is simpler if you have 2 SSDs the same size for this, but you could also use those 3 SSDs as raid1 if you have ports to spare. You would only get 180G capacity that way though since it has to mirror.

    I'll have to read up on this more.  I now see that having added the 120 GB + 60 GB, my cache shows up in unraid as 90 GB.  What advantage does this have over just having the single 120 GB and more space?  These drives aren't likely to be used for other stuff in the house as they can't hold much of an OS but the 250 could end up in a little linux box as a boot drive.

    One other thing. It is probably best to do the initial data load without caching, since cache won't have enough capacity to take it all and will just get in the way. You can also do the initial load without parity to get faster writes, as long as you have backups.

    I'll have to read up on this too

     

    Thanks again!

    ratio of storage : cache : parity & best allocation for my available drives

    I'm about 5 days into my unraid journey and am super stoked about the whole system.  I'm progressively moving data (mostly plex media, retro gaming resources and roms, and local home user files) off of my current desktop "server" to external USB 3 drives.  I'm adding drives and zeroing them in preparation for a big dedicated unraid server migration.

     

    I will be mostly serving files, running radarr / lidarr / sonarr + nzbget, plex, general file serving, time machine for 2 hackintoshes, and run a few VMs to learn on.  I have 3x8gb of ram with 3 slots open if that makes a difference.  Local home use with occasional remote plex streaming.

     

    Question 1

    Is there a proper ratio of storage : cache : parity?

     

    Question 2

    Does my planned (penciled in) drive allocation make sense

     

    SATA III Drives I plan have dedicated to unraid:

    Platter drives

    • 8TB WD
    • 5TB Seagate
    • 5TB Seagate
    • 5TB WD
    • 2TB Hitachi
    • 1TB Hitachi

    SSD Drives

    • 120 GB PNY
    • 60 GB OCZ

     

    Other drives that could go in the mix

    • 250 GB SSD
      • could be added for additional cache
    • 8TB WB USB 3
      • I was thinking about using for occasional backup of important files brough to friend's house.  I have google accounts for most important documents and photos but nothing formalized 

     

    I was thinking about the following:

    Parity - 10 TB

    • 8TB WD
    • 2TB Hitachi

    Cache - 180GB or 430 GB

    • 120 GB PNY
    • 60 GB OCZ
    • 250 GB (do I need this here really?)

    storage drives - 16 GB (for now)

    • 5TB Seagate
    • 5TB Seagate
    • 5TB WD
    • 1TB Hitachi

    Occasional backup of "important" files - not plex media

    • 8TB WB USB 3.0
      • I have one open SATA port on my mobo, should I just shuck this and put this in the array and use google or other cloud backup for document and photo backup?

    Thanks in advance!
