Riad config

[TechCparts]

I have built a custom nas out of a old custom computer i had lying around with the Rockstor Nas ISO. I have had this system running for half a year i have the drives stripped all together and i feel like thats gonna come back and hit me if one if the drives go out. i have a total of 7 drives that gives me a total of 3 TB but i would like to keep it close to that.... My question is which raid would you recommend

[GDRRiley]

raid 5 would give you 1 drive of failover. raid 6 would give you 2. both of these remove a drive or 2 from your pool

 3TB from 7 drives? Are the drives all similar? I don't know if BTRFS supports JBOD like UnRAID but provided they're all the same capacity and RPM you shouldn't have any trouble using RAID5/6. It'll give you fault tolerance and maximize what you can use. RAID5 is depreciated since when one drive dies you're screwed if a second fails while you're rebuilding the array. RAID6 will cost you 2 but it will offer better protection for the array.

 

Do understand though, RAID isn't a backup. Software can screw up and trash the array costing you everything regardless of parity.

With Rockstor, I would do a RAID5. Because it's a proper BTRFS implementation, it supports adding disks and extending your RAID a disk at a time as your needs increase. If you decide to go over 5 disks, then I would recommend moving it to a RAID6. I believe Rockstor like with hardware RAID's has the ability to migrate from RAID0 to RAID5 with the addition of a disk.

Just saying btrfs in rockstor has some major issues with raid 5/6 and data corruption and the write hole. It should go fine, but data loss is much more likely than something else.

 

What drives do you have? Id probably look to switching to something like unraid or mergerfs+snapraid.
