[Bug 140854] Re: Boot with Software Raid most times causes mdadm to not complete (possible race)
*** This bug is a duplicate of bug 139802 *** https://bugs.launchpad.net/bugs/139802 Hm... I just had to add the array definition to mdadm.conf: # definitions of existing MD arrays ARRAY /dev/md0 level=raid5 num-devices=2 UUID=c48b6ad2:935cba2b:e9e4094c:aa5ad989 No zeroing of superblocks was necessary. I did a few reboots and everything seems to work perfectly. -- Boot with Software Raid most times causes mdadm to not complete (possible race) https://bugs.launchpad.net/bugs/140854 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

*** This bug is a duplicate of bug 139802 *** https://bugs.launchpad.net/bugs/139802 I can confirm this fixed it, but I think it's still a bug in the mdadm tool or udev that handles it poorly 1. Use mdadm -E /dev/sdX1 and mdadm -E /dev/sdX device to examine the UUIDs of the raid array. One of them will be the one you no longer use, check the other drives and determine which one is no longer valid 2. Then unmount the raid array umount /dev/md1, mdadm --stop /dev/md1 3. Then mdadm --zero-superblock /dev/sdf 4. Then mdadm --zero-superblock /dev/sdh as I have to bad ones 5. Remount the array, Reboot Mine works perfect now :-) Please make sure you check your zeroing out the right drives before you do this.. -- Boot with Software Raid most times causes mdadm to not complete (possible race) https://bugs.launchpad.net/bugs/140854 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

*** This bug is a duplicate of bug 139802 *** https://bugs.launchpad.net/bugs/139802 I just tried the solution in the dup bug https://bugs.launchpad.net/ubuntu/+source/mdadm/+bug/139802 It looks like /usr/share/mdadm/mkconf >/etc/mdadm/mdadm.conf is detecting an array I dont have from somewhere. You can see the output of my mdadm.conf is totally messed up and this makes sense now why it's trying to add a drive to the array that doesnt exist. It could be an older one I had.. ?? ARRAY /dev/md0 level=raid5 num-devices=4 UUID=2fc65d39:8f7cbdb5:7072d7cc:0e4fe29d ARRAY /dev/md0 level=raid0 num-devices=2 UUID=db874dd1:759d986d:cc05af5c:cfa1abed ARRAY /dev/md1 level=raid5 num-devices=5 UUID=9c2534ac:1de3420b:e368bf24:bd0fce41 mdadm -E /dev/sdf UUID : db874dd1:759d986d:cc05af5c:cfa1abed mdadm -E /dev/sdh UUID : db874dd1:759d986d:cc05af5c:cfa1abed Interesting, so what happened is that I bought 3 new drives when I created this array, and the remaining two I formatted and put in here are the ones that still have the old UUID's. Since I applied the raid array in partitions for these drives instead of the physical device I have two UUIDs for two of my drives. Then I guess udev finds that at different times and causes it to fail if it tries to bring up the old array and add it to an existing one.. total race condition. So how do I get rid of the other UUIDs safely.. -- Boot with Software Raid most times causes mdadm to not complete (possible race) https://bugs.launchpad.net/bugs/140854 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 140854] Re: Boot with Software Raid most times causes mdadm to not complete (possible race)
I should experiment with my 4 disk raid 5 array disconnected. It's the one that has half SATA and half PATA drives as well. We have pretty much the same setup, and I mean I just formatted my drive and installed Gutsy so it's probably not just us. -- Boot with Software Raid most times causes mdadm to not complete (possible race) https://bugs.launchpad.net/bugs/140854 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 140854] Re: Boot with Software Raid most times causes mdadm to not complete (possible race)
I have exactly the same problem. My setup: Xubuntu Gutsy with latest Updates Athlon 64 1,6 MHz, 1GB RAM /dev/md0 is a Raid5 with 3x250GB disks (2x SATA and 1 PATA) I'm not too experienced with Linux, the only idea I came up with was disabling the Splashscreen with the status bar to see what's going on. It loads some hardware drivers I think and then it's the same as netslayer described, its printing "md: array md0 already has disks!" over and over again. I always have to try several times until the system boots but if it finally does everything is working fine, even the raid. -- Boot with Software Raid most times causes mdadm to not complete (possible race) https://bugs.launchpad.net/bugs/140854 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 140854] Re: Boot with Software Raid most times causes mdadm to not complete (possible race)
I just noticed the mdadm.conf I posted doesnt match my drive configuration and I dont think it's using it since all the UUIDs are on the partition tables.
