Hello, I am running small TrueNas installation on my HP N40L box in my office. Currently with just 2 HDDs in a MIRROR… I’d like to move from 2xHDD to 4xSSD RAIDZ1, so I need to replace all disks available in the box … I’d like to backup at least my VM Datasets. I have another synology box available, so I can use whatever is possible (smb, nfs, iscsi) … what would be the best approach to backup data and then restore to new disks… Thanks a lot!
OK so what I did was I bought a USB enclosure for 3.5" disks. ZFS is absolutely fine with 2 disks - one in the SATA inside the box and one connected via USB. Once I’ll replace all disks in the box, the USB disk will be the source for restore.
