Package: mdadm Version: 2.6.7-3.1 Severity: normal
The system is a clean 1-day old installation of Lenny. Doing tests of RAID re-assembly, by failing devices and having mdadm rebuild them. Had manually failed 2 devices on a 5-drive RAID5, causing it to stop. All attempts at forced re-assembly ended with SegFault, e.g. # mdadm -v -A --force --run /dev/md0 /dev/loop[0-4] mdadm: looking for devices for /dev/md0 mdadm: /dev/loop0 is identified as a member of /dev/md0, slot 0. mdadm: /dev/loop1 is identified as a member of /dev/md0, slot 5. mdadm: /dev/loop2 is identified as a member of /dev/md0, slot 2. mdadm: /dev/loop3 is identified as a member of /dev/md0, slot 3. mdadm: /dev/loop4 is identified as a member of /dev/md0, slot 1. mdadm: forcing event count in /dev/loop4(1) from 74 upto 80 Segmentation fault After many retries and failures, I downloaded older version of mdadm v2.6.4 from neilb's site and compiled it and it worked fine (no segfault): # ./mdadm -v -A --run --force /dev/md0 /dev/loop0 /dev/loop2 /dev/loop3 /dev/loo p4 /dev/loop1 mdadm: looking for devices for /dev/md0 mdadm: /dev/loop0 is identified as a member of /dev/md0, slot 0. mdadm: /dev/loop2 is identified as a member of /dev/md0, slot 2. mdadm: /dev/loop3 is identified as a member of /dev/md0, slot 3. mdadm: /dev/loop4 is identified as a member of /dev/md0, slot 1. mdadm: /dev/loop1 is identified as a member of /dev/md0, slot 5. mdadm: forcing event count in /dev/loop4(1) from 74 upto 80 mdadm: clearing FAULTY flag for device 3 in /dev/md0 for /dev/loop4 mdadm: added /dev/loop4 to /dev/md0 as 1 mdadm: added /dev/loop2 to /dev/md0 as 2 mdadm: added /dev/loop3 to /dev/md0 as 3 mdadm: no uptodate device for slot 4 of /dev/md0 mdadm: added /dev/loop1 to /dev/md0 as 5 mdadm: added /dev/loop0 to /dev/md0 as 0 mdadm: /dev/md0 has been started with 4 drives (out of 5) and 1 spare. Perhaps Lenny could consider the older, apparently more stable version of mdadm? -- Package-specific info: --- mount output /dev/hda1 on / type ext3 (rw,errors=remount-ro) tmpfs on /lib/init/rw type tmpfs (rw,nosuid,mode=0755) proc on /proc type proc (rw,noexec,nosuid,nodev) sysfs on /sys type sysfs (rw,noexec,nosuid,nodev) procbususb on /proc/bus/usb type usbfs (rw) udev on /dev type tmpfs (rw,mode=0755) tmpfs on /dev/shm type tmpfs (rw,nosuid,nodev) devpts on /dev/pts type devpts (rw,noexec,nosuid,gid=5,mode=620) /dev/hda9 on /home type ext3 (rw) /dev/hda8 on /tmp type ext3 (rw) /dev/hda5 on /usr type ext3 (rw) /dev/hda6 on /var type ext3 (rw) --- mdadm.conf # mdadm.conf # # Please refer to mdadm.conf(5) for information about this file. # # by default, scan all partitions (/proc/partitions) for MD superblocks. # alternatively, specify devices to scan, using wildcards if desired. #DEVICE partitions # auto-create devices with Debian standard permissions CREATE owner=root group=disk mode=0660 auto=yes # automatically tag new arrays as belonging to the local system HOMEHOST <system> # instruct the monitoring daemon where to send mail alerts MAILADDR root # definitions of existing MD arrays # This file was auto-generated on Sat, 20 Sep 2008 02:37:26 +0300 # by mkconf $Id$ --- /proc/mdstat: Personalities : [linear] [multipath] [raid0] [raid1] [raid6] [raid5] [raid4] [raid10] unused devices: <none> --- /proc/partitions: major minor #blocks name 3 0 78177792 hda 3 1 273073 hda1 3 2 1 hda2 3 5 4883728 hda5 3 6 2931831 hda6 3 7 2176776 hda7 3 8 393561 hda8 3 9 67513131 hda9 7 0 262144 loop0 7 1 262144 loop1 7 2 262144 loop2 7 3 262144 loop3 7 4 262144 loop4 7 5 262144 loop5 --- initrd.img-2.6.26-1-686: 29479 blocks scripts/local-top/mdadm sbin/mdadm lib/modules/2.6.26-1-686/kernel/drivers/md/md-mod.ko lib/modules/2.6.26-1-686/kernel/drivers/md/raid10.ko lib/modules/2.6.26-1-686/kernel/drivers/md/multipath.ko lib/modules/2.6.26-1-686/kernel/drivers/md/dm-mod.ko lib/modules/2.6.26-1-686/kernel/drivers/md/raid456.ko lib/modules/2.6.26-1-686/kernel/drivers/md/raid1.ko lib/modules/2.6.26-1-686/kernel/drivers/md/dm-log.ko lib/modules/2.6.26-1-686/kernel/drivers/md/dm-mirror.ko lib/modules/2.6.26-1-686/kernel/drivers/md/linear.ko lib/modules/2.6.26-1-686/kernel/drivers/md/raid0.ko etc/mdadm etc/mdadm/mdadm.conf --- /proc/modules: raid10 18560 0 - Live 0xee94a000 raid456 117264 0 - Live 0xee964000 async_xor 3520 1 raid456, Live 0xee91a000 async_memcpy 2304 1 raid456, Live 0xee918000 async_tx 6284 3 raid456,async_xor,async_memcpy, Live 0xee8cf000 xor 14696 2 raid456,async_xor, Live 0xee926000 raid1 18016 0 - Live 0xee920000 raid0 6368 0 - Live 0xee8ae000 multipath 6112 0 - Live 0xee83b000 linear 4544 0 - Live 0xee866000 md_mod 67036 6 raid10,raid456,raid1,raid0,multipath,linear, Live 0xee930000 dm_mirror 15104 0 - Live 0xee818000 dm_log 8452 1 dm_mirror, Live 0xee8a6000 dm_mod 46184 2 dm_mirror,dm_log, Live 0xee8c2000 --- /var/log/syslog: --- volume detail: --- /proc/cmdline root=/dev/hda1 ro quiet --- grub: kernel /boot/vmlinuz-2.6.26-1-686 root=/dev/hda1 ro quiet kernel /boot/vmlinuz-2.6.26-1-686 root=/dev/hda1 ro quiet single kernel /boot/vmlinuz-2.6.24-1-686 root=/dev/hda1 ro quiet kernel /boot/vmlinuz-2.6.24-1-686 root=/dev/hda1 ro quiet single -- System Information: Debian Release: lenny/sid APT prefers testing APT policy: (500, 'testing') Architecture: i386 (i686) Kernel: Linux 2.6.26-1-686 (SMP w/1 CPU core) Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/bash Versions of packages mdadm depends on: ii debconf 1.5.22 Debian configuration management sy ii libc6 2.7-13 GNU C Library: Shared libraries ii lsb-base 3.2-20 Linux Standard Base 3.2 init scrip ii makedev 2.3.1-88 creates device files in /dev ii udev 0.125-6 /dev/ and hotplug management daemo Versions of packages mdadm recommends: ii module-init-tools 3.4-1 tools for managing Linux kernel mo ii postfix [mail-transport-agent 2.5.5-1.1 High-performance mail transport ag mdadm suggests no packages. -- debconf information: * mdadm/autostart: true mdadm/mail_to: root mdadm/initrdstart_msg_errmd: * mdadm/initrdstart: all mdadm/initrdstart_msg_errconf: mdadm/initrdstart_notinconf: false mdadm/initrdstart_msg_errexist: mdadm/initrdstart_msg_intro: mdadm/autocheck: true mdadm/initrdstart_msg_errblock: mdadm/start_daemon: true -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
