I need advice.
I installed a 4x8TB SATA disk (+1xSSD per system) on my home NAS (Supermicro X7SPA-HF)
BTRFS volume, RAID 10, one big 16TB pool and Rockstor 18.104.22.168
Now one of the drives is faulty and I have not found ANY simple procedure to replace that drive so that rocktor can handle the exchange and data recovery ideally with a “one click” solution. In most procedures, backup the data, break the pool and rebuild, restore the share, and load the data from the backup. 16TB of data is really not easy and certainly not cheap to just back it up somewhere, because the system is not able to easily deal with such a basic issue as one defective disk in a raid.
So how do you do it WITHOUT shutting down the NAS, without losing data, and ideally without breaking access to services like NFS and Samba?
Is it possible to put buttons or some menu item in future versions of rockstore that would solve this easily? When I disconnect the faulty disk while it is running, it is deattached, the new one will not take it, resize/repool and deleting the disk does not work, because raid 10 needs 4 disks, etc.
