Bonjour,

En d=E9finissant explicitement la taille max des blocks en read et write lo=
rs du montage nfs :

rsize=3D1048576,wsize=3D1048576 (1MB)

Avec le kernel 6.1.0-43, =E7a mache !

Pour info: ~$ dd if=3D/dev/zero of=3D/mnt/nfs_share/toto bs=3D1M count=3D2 =
oflag=3Ddirect

Le workaround est solide et les processus de mise =E0 jour peuvent continue=
r. Je n'ai juste pas une explication plus pr=E9cise.

Merci de m'avoir lu.

Jacques
