Let me first explain the scenario first
Currently we are running SM server with 250 website and 8TB of data, but its a standalone server with no data backup.
We have setup new server with primary/secondary SM server and shared NFS storage with RAID 10 configured. So in total 3 servers for our new setup.
We want to migrate all the data with SM license to new server but the data copy is pain, with help of robocopy it took almost 4 days to transfer 8TB of data. Since its production server we cannot afford huge downtime and have to do it with minimum downtime.
The re-sync also consumes lot of time so we cannot move all the domains at same time. So below are the 2 options we have with us
We take huge downtime like 4 hrs or more and change domain path and re-synce data from one server to another.
Map the shared storage in current production server move the data of one website at a time change its domain path so that all the new data is written on shared storage.
Once all the website domain path are shifted to shared storage, change the SM license and domain path to meet new environment.
The option 2 seems doable but facing issue while changing the domain path.
1) We tried changing the domain path in domains.jason file and start stop SM server, but doing this the service does not start. Once we change the domain path to original, service starts within 2-3 seconds.
2) Tried to attach/detach the domain but it give me error. When I map the NFS storage as H: it gives me error "Invalid folder path or domain name" and when I give the UNC storage path it gives error "domain path does not exists".
I tried creating new domain on UNC path it creates it properly, just the problem is with moving domain.
The same path is mapped in new server and it works properly there, so what am I doing wrong here.
If it is permission issue what could it be. NFS client is installed on all the SM servers.
Please can someone help me here.
