We are great problem - we have reinstalled the OS on RHEL 6 accidentally - means all data and luns gone fron server.
we dont have backup as it was a newly build.
Now my question ie:
1. Is it possible to recover OS or data from reinstalled OS or can we go back to its previous condition?
2. LUNS which are connected to this server have huge data and now they are disconnected.
so how we can mount or connect those LUNS without hamper the Data - as if we use PVcreate or Vgcreate again on those luns - it will destroy all data on it?
Please help soon
