Description Niels de Vos 2016-05-05 11:27:41 UTC 
In the current upstream Gluster, the write-behind cache supports a xlator option 'resync-failed-syncs-after-fsync', which has Gluster retain the cache on fsync failure, until the file descriptor is flushed/closed.  With this QEMU, when using the libglusterfs library, can perform retries on a fsync failure.

However, QEMU has no way of determining at runtime if this xlator option is supported.  The api glfs_set_xlator_option() will return success even for unknown options.  It would be very useful for us to be able to determine if we can use the new xlator option - until we can determine if it is support, QEMU must act as if it is not supported.

Comment 2 Stefano Garzarella 2019-09-09 09:14:48 UTC 
Is glfs_set_xlator_option() fixed or there is any way in the current API to know if 'resync-failed-syncs-after-fsync' is supported or not?
