fiore00713 Posted January 17, 2018 Share Posted January 17, 2018 As the title suggests I'm looking to convert my cache from a RAID1 to RAID10 I currently have a 2-disk RAID1 setup that I'd like to convert to a 4-disk RAID10 I've found the command for changing the modes but I'm having trouble tracking down any additional steps or precautions to take Also, I'd assume this is a destructive process. Meaning, the drives will be wiped, the new RAID will be created and then I will need to re-copy data and configure shares Has anyone had experience in completing this and can provide any insight? Thanks Quote Link to comment

It's not, but a backup before starting is always a good idea. https://lime-technology.com/forums/topic/46802-faq-for-unraid-v6/?do=findComment&comment=480421 Quote Link to comment

Maybe you can confirm? My assumption is, I have 2x disks in RAID1 currently. Stop array Add the 2 new disks to the cache section (4 total now) Start array Go into Cache settings Change mode and rebalance [magic happens] RAID10 all set with existing data intact Quote Link to comment

greg2895 Posted January 17, 2018 Share Posted January 17, 2018 I have found no difference with raid 10 and raid 1 with my 4 ssds. Quote Link to comment

Im looking to increase the performance of my unraid Cache pool by converting a pool of 3 SSDs in RAID1, to 4 in RAID10. Has anyone seen any tangible performance increases in RAID10? Or is it just a waste of money (unless youre doing benchmarking)? I know Greg2895 says he noticed no difference, but surely there must be something in it? Quote Link to comment
