https://bugzilla.suse.com/show_bug.cgi?id=1214004 Bug ID: 1214004 Summary: Rebuilding MD-RAID brings system almost to a halt Classification: openSUSE Product: openSUSE Distribution Version: Leap 15.5 Hardware: x86-64 OS: Other Status: NEW Severity: Major Priority: P5 - None Component: Kernel Assignee: kernel-bugs@opensuse.org Reporter: Ulrich.Windl@rz.uni-regensburg.de QA Contact: qa-bugs@suse.de Target Milestone: --- Found By: --- Blocker: --- (This problem is not new, but as it's still there, I thought it's time to report it) My system has one Intel on-board SATA RAID controller: 09: PCI 1f.2: 0104 RAID bus controller [Created at pci.386] Unique ID: w7Y8.IzwgmJk+U9F SysFS ID: /devices/pci0000:00/0000:00:1f.2 SysFS BusID: 0000:00:1f.2 Hardware Class: storage Model: "Intel SATA Controller [RAID mode]" Vendor: pci 0x8086 "Intel Corporation" Device: pci 0x2822 "SATA Controller [RAID mode]" SubVendor: pci 0x1043 "ASUSTeK Computer Inc."

When the system hung on reboot after upgrading from Leap 15.4 to 15.5, I pressed the reset button after having waited a long time. Unfortunately during boot that caused the OS RAID to be "unclean", forcing a rebuild: Aug 05 00:23:22 pc kernel: md/raid1:md126: not clean -- starting background reconstruction Aug 05 00:23:22 pc kernel: md/raid1:md126: active with 2 out of 2 mirrors md126 : active raid1 sda[1] sdb[0] 1953497088 blocks super external:/md127/0 [2/2] [UU] [==>..................] resync = 12.4% (243003648/1953497088) finish=236.9min speed=120296K/sec md127 : inactive sdb[1](S) sda[0](S) 10402 blocks super external:imsm When the MD-RAID is rebuilding some commands take almost forever, also giving nonsense results. For example: package cpupower-5.14 is not installed

(First it said the package is not installed, then it obviously was) Of course that is a bug in RPM, most likely, too. Anyway I think the default rebuild speed should reserve a bigger amount of bandwidth for application use (i.e.: no for rebuilding) I improved the situation limiting the rebuild speed to 50MB/s or so (see also https://superuser.com/a/625724/964771): sudo sh -c "echo 50000 > /proc/sys/dev/raid/speed_limit_max" -- You are receiving this mail because: You are on the CC list for the bug.
