I build my TrueNAS using the Threadripper Platform it has 64GB of EEC RAM
24 Drive bays
8x 14TB SAS
4x 12TB SATA
4x 10TB SATA
4x 8TB SATA
I added these drivers over time 2 per week in 2 drive mirrors.
I installed the TrueNAS image on one 120GB NVMe (bad move I know)
2 of the SAS Drives have since degraded and the 120GB NVMe failed around the same time
I installed the TrueNAS again on 2x 1TB NVMe I was using in another system but I cannot import the pool I get the message insufficient replicas.
The two drives that are broken are not in the same mirror so there is one drive in each mirror that is good and I have two new 14tb drives installed ready to replace the broken ones, as I cannot import the pool i am finding it hard to resilver the new drives.
Any help would be greatly apprenticed I have no backup of the data but can recreate the data it will take months, I am in the process of getting a backup server so if I cannot restore the drives I will split the drives I have now between the two servers and add more disks to both servers at the same time
