Upgrading to UnRAID v6


Recommended Posts

We STRONGLY RECOMMEND upgrading to the latest v6!

 

* ALL versions prior to the current v6 have known security vulnerabilities, making them vulnerable to attack by an infected machine on your local network.

 

* LimeTech has been seriously considering for some time moving ALL older versions to End-Of-Life, all versions prior to v6.

 

* Maintenance and support is becoming harder and scarcer as time goes by.  There are fewer and fewer people familiar with your version able or willing to help.

 

* Numerous bugs have been fixed.  You may be running without issue now, but something can still go wrong, or you may try something different, and run into an issue long fixed in newer versions.

 

* You're missing out on a lot of new features, and perhaps better performance too.

 

* One very important improvement is Notifications, makes it a better NAS!  The system will inform you immediately of problems.

 

* After upgrading, you will still be able to run all of your favorite applications, and they may even run better, because in v6 there are multiple ways to run them.

 

Please check out the Upgrading to UnRAID v6 guide.

Ok, this may seem a bit odd, but most of my UNRAID servers are way back on 4.5.3  They have been rock stable forever, with the exceptions of power outages, and a failed motherboard, and a few power supplies here and there over the years.

 

I am finally done with my tests on 6.x... and am ready to commit to retiring and upgrading from the 4.x world...  But, I see no link that actually takes me to any upgrade guide now.  Am I missing something?

Doesn't look like that is going to help much from your very old version.

 

First thing, your hardware must support 64-bit.

 

How big is your flash drive, and how much RAM do you have?

 

Any RAID controllers involved?

The oldest one is now running a Core 2 Duo (64-bit) E7200, with 2 GB of RAM, expandable up to 4 GB of RAM.

 

It is on a 4GB Flash drive

 

SATA drives are running on:

1 ea - SuperMicro SAT2-MV8 (running in PCI mode) (8-drives)

1 ea - Promise FASTTRAK S150 TX4 PCI card (4-drives)

  The rest of the drives are on the Motherboard SATA ports (4-drives)

You really need to upgrade this to 4GB if you want to use it with the current v6 (which is now the recommended minimum).   It will probably run most basic functionality with 2GB but certain features (such as OS upgrade via GUI) may well fail to work correctly.

It looks like I will just need to copy/move the files over to new/re-formatted drives on the array for use under V6.x.  Not fun, but needed it looks like.

 

it also seems it may be time to consider a motherboard/SATA controller upgrade, (but probably after I migrate to V6.x I think).  8 or 16 port SATA controllers on PCI-e will definitely increase parity check/rebuild speed.

 

I was trying to delay any big changes since the hardware has been working so well for so many years...  but looking at options now, I am not really sure.

various system component speeds - - I made this little breakdown of various system components to assist my decision making on my upgrade.  depending on actual use, this can be used to help decide where to focus on upgrades on hardware...  I Hope someone else may also benefit from it.

 

Newer SSDs, (SATA and NVME) while not listed here, are so fast overall for actual needs, the faster options only really benefit in parity check and array rebuilds.  Read/write speeds of 500/400MB/sec per device are screaming fast overall for most unraid uses.  It may be very beneficial to performance however to still use a higher end and faster drive for Parity and/or cache drives.  But watch the caveat, some faster drives also have reduced MTBF ratings...

 

Here is the speed breakdowns for various components, using general best case data on a well designed system:

 

PCI-E to replace old PCI or PCI-X SATA controller cards - - 
and - Speed comparisons of various system components

 

SATA - 
SATA 1 - 1.5 Gb/sec = 150 MB/sec
SATA 2 - 3.0 Gb/sec = 300 MB/sec
SATA 3 - 6.0 Gb/sec = 600 MB/sec

 

Hard Drives
5400 RPM up to ? - up to 180-210 MB/sec - 
7200 RPM up to 1030 Mb/sec disc to buffer - up to 255 MB/sec - 204 MB/sec sustained


NETWORK limits 94% efficiency- - 
10Mb = 1.18 MB/sec
100Mb = 11.8 MB/sec
1Gb = 118 MB/sec
2.5Gb = 295 MB/sec
10Gb = 1180 MB/sec


PCI 32-bit 33 Mhz
133.33 MB/sec = 8 drives = 16.66 MB/sec per drive!
133.33 MB/sec = 4 drives = 33.33 MB/sec per drive!
133.33 MB/sec = 2 drives = 66.66 MB/sec per drive!

 

PCI 32-bit 66 Mhz
266 MB/sec = 8 drives = 33.25 MB/sec per drive!
266 MB/sec = 4 drives = 66.5 MB/sec per drive!
266 MB/sec = 2 drives = 133 MB/sec per drive!

 

PCI-X 64 bit 133 Mhz
1072 MB/sec = 8 drives = 134 MB/sec per drive!
1072 MB/sec = 4 drives = 268 MB/sec per drive!
1072 MB/sec = 2 drives = 536 MB/sec per drive!


PCI-E 3.0 1 lanes = 1GB/sec = 16 drives = 62.5 MB/sec per drive!
PCI-E 4.0 1 lanes = 2GB/sec = 16 drives = 125 MB/sec per drive!

PCI-E 3.0 1 lanes = 1GB/sec = 8 drives = 125 MB/sec per drive!
PCI-E 4.0 1 lanes = 2GB/sec = 8 drives = 250 MB/sec per drive!

PCI-E 3.0 1 lanes = 1GB/sec = 4 drives = 250 MB/sec per drive!
PCI-E 4.0 1 lanes = 2GB/sec = 4 drives = 500 MB/sec per drive!


PCI-E 3.0 2 lanes = 2GB/sec = 16 drives = 125 MB/sec per drive!
