Hi everyone, hope y’all doing great!
So I have an issue, I am currently running truenas and, my main storage pool is a stripe array of 2x2tb drives (not great i know but I did with what I had laying around.). I decided i was going to upgrade drives as I am running out of space and it’s not great reliability wise so I am going to buy 3 8tb drives to put in a raidz1 witch should give me much needed space.
But here is my problem, i don’t know how to migrate the data from my old pool to the new one. I can’t just create the new pool and transfer the data, as I don’t have enough sata ports to plug all the drives at the same time(And I don’t want to buy an hba just for that). I don’t want to buy one big drive to copy all the data as well, i won’t have enough money left once I’ll have bought the drives.
The two Ideas i thought of were to either change the drives one by one in truenas but from my understanding, you can’t just add a drive and change the pool from a striped array to a raidz1. The other (very janky, I know) idea I had would be to use some old USB drive enclosures to connect my old array to truenas and then copy the data but I don’t even know if truenas would still see the drives as they are ounce they would be in USB enclosures.
So if any of you has a great solution for me, I’d be very grateful.
In any case, great evening everyone.
