Deze release is opmerkelijk vanwege de toevoeging van ondersteuning voor Linux-kernel 6.6 en de poging om een probleem op te lossen dat leidt tot gegevensbeschadiging (het nullen van delen van blokken) in bestanden na het kopi\u00ebren.       <\/p>\n<p>Aanvankelijk werd gedacht dat het probleem alleen voorkwam in de 2.2.x-tak en werd veroorzaakt door een fout in het blokkloningsmechanisme dat in OpenZFS 2.2.0 is opgenomen, waarmee een kopie van een bestand of een deel ervan kan worden gemaakt zonder gegevens te dupliceren, door in de tweede kopie verwijzingen naar de al bestaande gegevensblokken van het originele bestand te gebruiken zonder ze daadwerkelijk te kopi\u00ebren. In versie OpenZFS 2.2.1 is het blokkloningsmechanisme standaard uitgeschakeld om het probleem te blokkeren, en is er een instelling zfs_bclone_enabled toegevoegd om ondersteuning voor deze modus weer in te schakelen.     <\/p>\n<p>Later, the developers reported reproducing the issue even in configurations with the OpenZFS 2.1.x branch. It was also confirmed that the problem does not occur solely on systems with older releases of the coreutils package \u2014 the error could be reproduced in FreeBSD and in Linux distributions with the latest coreutils 9.4 release.     <\/p>\n<p>File corruption occurs under quite rare circumstances; for instance, executing the command \u00abemerge -1 dev-lang\/go\u00bb in Gentoo leads to the installation of the Go language tools with file corruption in the directory \/usr\/lib\/go\/pkg\/tool\/linux_amd64\/compile. It is assumed that the error began to manifest after the default setting of the parameter \u00abzfs_dmu_offset_next_sync=1\u00bb in version openzfs 2.1.4. The source of the error has not been identified yet. As a recommended workaround to block the error, it is suggested to set the parameter \u00ab\/sys\/module\/zfs\/parameters\/zfs_dmu_offset_next_sync\u00bb to 0.<br \/>\n<br \/>Bron: <a
