File 0035-udev-add-no-devices-option-for-calling-mdadm-detail.patch of Package mdadm
From 1a52f1fc0266d438c996789d4addbfac999a6139 Mon Sep 17 00:00:00 2001 From: Coly Li <colyli@suse.de> Date: Wed, 31 Jul 2019 13:29:30 +0800 Subject: [PATCH 2/2] udev: add --no-devices option for calling 'mdadm --detail' Git-commit: 1a52f1fc0266d438c996789d4addbfac999a6139 Patch-mainline: mdadm-4.1+ References: bsc#1139709 When creating symlink of a md raid device, the detailed information of component disks are unnecessary for rule udev-md-raid-arrays.rules. For md raid devices with huge number of component disks (e.g. 1500 DASD disks), the detail information of component devices can be very large and exceed udev monitor's on-stack message buffer. This patch adds '--no-devices' option when calling mdadm by, IMPORT{program}="BINDIR/mdadm --detail --no-devices --export $devnode" Now the detailed output won't include component disks information, and the error message "invalid message length" reported by systemd can be removed.
