The basics
EX470
2GB ram
non upgraded processor
runing HP MSS v3
eSATA 4 bay enclosure attached and full
(Mediasonic ProBox 4 Bay 3.5' SATA Hard Drive Enclosure - USB 3.0 & eSATA (HF2-SU3S2))
present drive size:
2x1TB
2x1.5TB
4x2TB (one is the sys drive)
All data backed up and removed & fresh factory reset install done - server is empty
And i'm about to have a revolution on my hands at home if i dont get this working again and soon.
problem is we ran out of space... and before someone comes up with the add an external drive answer .. done that as noted above. and swapping out the 1TB and 1.5Tb drives with 2Tb is just a very temporary and costly solution for the gain.
so what i'm trying to do is swap out 2 of the old 1TB drives with 2 4TB ones.
Following the instructions on http://forum.wegotserved.com/index.php/topic/16580-guide-how-to-make-gpt-4k-sector-drives-and-3tb-drives-work-as-storage-pool-drives-in-whs-pp3/
I run into a small formatting problem on step 10 the format just won't successfully complete on quick format but i got it to complete on the long one.
However on completing the whole guide there is a problem
After the format the disk shows as 3725GB capacity and 1677GB free space 2TB is listed as used space.
Registry changes updating the disk size change nothing and after reboot the disk does show back in the pool in the Server console but it is back to 1.64TB i had originaly and the total capacity of the pool is the same 4.8TB for the 3 drives as before
Additionally the registry change from step 11 at Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows Home Server\Storage Manager\Disks\
reverts to the original size of 1801763774464
but the changes in size from step 12 at Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows Home Server\Storage Manager\Volumes\
stay changed to 4000650887168
Anyone have an idea what the problem is? and how to fix it?
And here is the question i kinda need clarified:
Taking into account that AHCI supports Hot Plugging and IDE does not and if i can see the full 4TB partition in Disk Management before adding the drive to the pool does that mean that the drives are set up in the BIOS as AHCI and not IDE?
reason for question is that in all the searching for the 'how' to do it i ran across a comment for 4TB drives on a EX495 where the person stated: "I had get the new intel matrix drivers and also make a vga cable to change the drives it the BIOS to AHCI, then I followed this post (from above)"
i Know there are differences in the configuration and hardware on the 2 models so not sure if and what applies from the EX495.
Plus this post Ex470 Hdd Limitation does not indicate a BIOS problem just a software (WHS 2003) issue which the above workaround should 'fix'
I'm not opposed to getting the vga cable to change the BIOS if that IS the solution... i just don’t want to get them and it's not the solution...
Has anyone managed to get 4TB drives into pool on the EX470?
If it's a BIOS problem can i bypass it by slotting the drives in the enclosure bay i have that i know supports >2TB drives? or do i run into the same problem? ie is the eSATA controller on the EX470 separate from the internal drive controller?
Any and all help is very appreciated...
