OS6 horizontal expansion - adding a larger drive
apologies if this has been discussed before, I cannot find a definite answer.
I am on OS4 on my RN Pro6 and I am planning of migrating to OS6. I currently have 3x4TB HDDs. I am thinking of expandin...
Yes, even when creating a new volume it will create the RAID layer with 4x4TB and see that there's only one higher capacity disk so there's not room to vertically expand yet. If you had two 6TB disks installed when creating the volume it would do the vertical expansion after creating the 4x4TB layer.
1. For vertical expansion you need at least two higher capacity disks using the default X-RAID2 (single-redundancy). If using dual-redundancy (uses RAID-6) you'd need four higher capacity disks for vertical expansion. This is true both of RAIDiator-x86 and OS6.
2. There are some 4TB disks on the compatibility list for the Pro 6. OS6 has better software support for high capacity disks than RAIDiator-x86 did. I think you should find that 6TB disks work well for you based on what I've read of the experiences of others.
Note that running OS6 on your system is unsupported, but then you should be backing up your important data regularly anyway and you'd need to before upgrading to OS6 as that process does involve a factory default (wipes all data, settings, everything).
thanks mdgm as usual - and nice hearing from you again!
All pretty much clear. Just wanted to double check that I am not expanding, I'm reinstalling (obviously!) on single redundancy. Can you confirm the same process will apply - hence 4+4+4+6 will give me 4+4+4 + 4(redundancy) for now?
Cheers!
