From 1e93d0d15913c3fa6d0de5af3fb5e4e3b3f068da Mon Sep 17 00:00:00 2001 From: Blazej Kucman Date: Fri, 17 Jan 2020 15:24:04 +0100 Subject: [RHEL8.2 PATCH 61/61] imsm: fill working_disks according to metadata. Imsm tracks as "working_disk" each visible drive. Assemble routine expects that the value will return count of active member drives recorded in metadata. As a side effect "--no-degraded" doesn't work correctly for imsm. Align this field to others. Added check, if the option --no-degraded is called with --scan.
