Cannot change ownership to uid 1000

Hallo zusammen

Ich versuche iobroker mittels Kubernetes auf einem NFS-Volume zu installieren. Dabei erhalte ich folgende Meldung:
tar: opt/iobroker/iobroker-data/files/admin.admin/custom/i18n/pt.json: Cannot change ownership to uid 1000, gid 1000: Operation not permitted
tar: opt/iobroker/iobroker-data/files/admin.admin/custom/i18n/fr.json: Cannot change ownership to uid 1000, gid 1000: Operation not permitted

tar: opt/iobroker/iobroker-data/files/admin.admin/custom/i18n/nl.json: Cannot change ownership to uid 1000, gid 1000: Operation not permitted

Den Ordner iobroker auf dem NFS-Share wird beim Startup angelegt und div. Files dort abgelegt. Die Berechtigung per se müsste vorhanden sein.
Leider bin ich etwas ratolos wo ich suchen soll.

Danke.
