From 23f45965a0abe3506885c8e8005ee79473a66422 Mon Sep 17 00:00:00 2001 From: Xiao Ni Date: Wed, 22 May 2024 16:50:44 +0800 Subject: [PATCH 082/157] mdadm/tests: 03assem-incr enhance It fails when hostname lenght > 32. Because the super1 metadata name doesn't include hostname when hostname length > 32. Then mdadm thinks the array is a foreign array if no device link is specified when assembling the array. It chooses a minor number from 127.
