I'm using Ignite 2.6 with the C# client.

I have a running cluster that I was debugging. All requests were read only
(there were no state mutating operations running in the cluster.

I terminated the one server node in the grid (running in the debugger) to
make a small code change and re-run it (I do this frequently). The node may
have been stopped for longer than the partitioning timeout.

On re-running the server node it failed to start. On re-running the
complete cluster it still failed to start, and all other nodes report
failure to connect to a inactive grid.

Looking at the log for the server node that is failing I get the following
log showing an exception while initializing a WAL segment. This failure
seems permanent and is unexpected as we are using the strict WAL atomicity
mode (WalMode.Fsync) for all persisted regions.Is this a recoverable error,
or does this imply data loss? [NB: This is a dev system so no prod data is
affected]]
