Hello,

My Percona 5.7.16 server creates the xb\_doublewrite file at startup despite the ‘innodb\_doublewrite = 0’ setting (running on ZFS). However, the file doesn’t ever seem to be written to after the startup.

Is any way to disable creating this file at startup? I did try setting innodb\_parallel\_doublewrite\_path to empty string, OFF, 0, etc, but it either ended with server refusing to start (empty), or the file being created (eg. ‘OFF’).

Thanks,  
Kind regards,

---

It’s a bug that this file is being created with doublewrite disabled. Please follow this bug: [url][https://bugs.launchpad.net/percona-server/+bug/1570682[/url]](https://bugs.launchpad.net/percona-server/+bug/1570682%5B/url%5D) (and click Affects Me)
