Versity ScoutFS Release Notes

*Jun 3, 2025*
|
||||
|
||||
Fix a bug that could cause indefinite retries of failed client commits.
|
||||
Under specific error conditions the client and server's understanding of
|
||||
the current client commit could get out of sync. The client would retry
|
||||
commits indefinitely that could never succeed. This manifested as
|
||||
infinite "critical transaction commit failure" messages in the kernel
|
||||
log on the client and matching "error <nr> committing client logs" on
|
||||
the server.
|
||||
|
||||
Fix a bug in a specific case of server error handling that could result
|
||||
in sending references to unwritten blocks to the client. The client
|
||||
would try to read blocks that hadn't been written and return spurious
|
||||
errors. This was seen under low free space conditions on the server and
|
||||
resulted in error messages with error code 116 (The errno enum for
|
||||
ESTALE, the client's indication that it couldn't read the blocks that it
|
||||
expected.)
