Zpool upgrade

[Yoyospectre]

Bonjour,
suite a la mise a jour de 8.2 à 8.3 j'ai une "alerte" :
the volume RaidZ (ZFS) status is UNKNOWN: The pool is formatted using an older on-disk format. The pool can still be used, but some features are unavailable.Upgrade the pool using 'zpool upgrade'. Once this is done, the pool will no longer be accessible on older software versions.

Ne maitrisant pas le sujet, deux questions:
- Realiser cela entraine-t-il la perte des donnees stockees ?
- Si non, comment procede-t-on ? Je n'utilise que l'interface web et m'aide des tutos..

Cordialement.

Note that updating an existing v15 pool is optional. However, any new pools/volumes that you create will be v28.
