File 0001-Assemble-keep-MD_DISK_FAILFAST-and-MD_DISK_WRITEMOST.patch of Package mdadm
From 0833f9c3dbaaee202b92ea956f9e2decc7b9593a Mon Sep 17 00:00:00 2001 From: Gioh Kim <gi-oh.kim@profitbricks.com> Date: Tue, 6 Nov 2018 15:27:42 +0100 Subject: [PATCH] Assemble: keep MD_DISK_FAILFAST and MD_DISK_WRITEMOSTLY flag Git-commit: 0833f9c3dbaaee202b92ea956f9e2decc7b9593a Patch-mainline: mdadm-4.1+ References: jsc#SLE-10078, jsc#SLE-9348 Before updating superblock of slave disks, desired_state value is set for the target state of the slave disks. But it forgets to check MD_DISK_FAILFAST and MD_DISK_WRITEMOSTLY flags. Then start_arrays() calls ADD_NEW_DISK ioctl-call and pass the state without MD_DISK_FAILFAST and MD_DISK_WRITEMOSTLY. Currenlty it does not generate any problem because kernel does not care MD_DISK_FAILFAST or MD_DISK_WRITEMOSTLY flags.
