> {color:#0e101a}As a last compaction step, the server deletes the compacted
> .crf file. The deletion is done in the following way:{color}
> # {color:#0e101a}Write delete operation (delete ".crf" file) in the ".if"
> file. {color}
> # {color:#0e101a}Delete .crf file{color}
> {color:#0e101a}The problem with server startup happens in the following
> scenario:{color}
> # {color:#0e101a}The server writes the delete operation (for .crf file) in
> the ".if" file. The write is not immediately flushed to the ".if" file, but
> it goes to the async write buffer.{color}
> # {color:#0e101a}The server deletes the ".crf" file.{color}
> # {color:#0e101a}The forceful restart (of the machine where the server
> resides) happens before the async write buffer is flushed to the ".if" file.
> This scenario leaves the ".if" file not updated, and therefore server startup
> fails later on from the persisted region data.{color}
>
> {color:#0e101a}To avoid the above issue, we can use the existing parameter in
> a geode that forces the server to write synchronously to the ".if"
> file:{color}
> {code:java}
> --J=-Dgemfire.syncMetaDataWrites=true
> {code}
> {color:#0e101a}This parameter is not mentioned anywhere in the documentation.
> So it would be good to add it to the following document:{color}
> {color:#0e101a}[https://geode.apache.org/docs/guide/114/managing/disk_storage/managing_disk_buffer_flushes.html]{color}
>
> {color:#0e101a}Changing this parameter's default value to true would also be
> good. {color}{color:#0e101a}This parameter should not affect performance as
> the ".if" file is not updated frequently.{color}
