Keyspaces missing after restarting cassandra service

Hello,

After restarting the cassandra, all of my keyspaces got missing. I can only
see system_traces, system, dse_system. I didn't make any changes to
cassandra.yaml.

But, I can see all the keyspaces data in my */data/ *directory. Is there
anyway to access those lost keyspaces through cqlsh?

Can someone help me with a solution?

This sort of problem is best debugged interactively, for example in
#cassandra on freenode IRC.

But... start by :

1) checking permissions for relevant directories
2) looking in system.log to see if Cassandra tried and failed to find your
CFs
