[Bug 942106] Re: software raid doesn't assemble before mount on boot
This doesnt look fixed for me too. I run a software raid and the "solution" posted by Josh is the only one which is working in my case. I have a software raid5 and my root partition is not part of the array.

[Bug 942106] Re: software raid doesn't assemble before mount on boot
Hi,
This fix does not work for me. I have a system with a single md raid 5 array
with 5 disks, and root on a seperate non-raid disk. With the default
bootdegraded=false my system frequently drops to the initramfs prompt with the
usual timed out message. With BOOT_DEGRADED=true set in the mdadm initramfs
config, the system frequently drops to the initramfs prompt complaining of 2 of
5, 3 of 5, or 4 of 5 disks failed to be added to the array.
I was able to fix the problem by horrible hack by adding a hard sleep after the
udevadm settle call in wait_for_udev
(in /usr/share/initramfs-tools/scripts/functions)
# Wait for queued kernel/udev events
wait_for_udev()
{
command -v udevadm >/dev/null 2>&1 || return 0
udevadm settle ${1:+--timeout=$1}
sleep 15
}
With this change the system reliably boots (albeit slightly slower).
with the raid properly detected with all 5 drives.
This suggests to me that udevadm settle is not doing what it's supposed
to be doing (waiting for the relevant controller/drives to fully come
up.)
I am running Ubuntu 13.10 on an Asus M2N-E Motherboard with 6 disks
attached to the onboard sata ports. (One with the root partition and
the other 5 as part of the raid 5 array).
This board runs an older AMD-based Nvidia chipset and does not support
ahci, so the sata drives run through the sata_nv module.

[Bug 942106] Re: software raid doesn't assemble before mount on boot
The patch of https://bugs.launchpad.net/ubuntu/+source/update-manager/+bug/942106/comments/5 does not work in following case: - Ubuntu 12.04 - partitionable RAID-1 on two complete disks sda and sdb, giving array md0. Root partition is md0p1, swap partition is md0p2. - One disk physically removed before boot. - boot degraded arrays is requested The system reports Mount failed, /dev/disk/my-uuid/ busy. This /dev/disk/my-uuid/ points to /dev/sda1. Solution: add a second wait_for_udev at the end of the local-premount/mdadm script. This results in the script: . /scripts/mdadm-functions . /scripts/functions wait_for_udev degraded_arrays || exit 0 mountroot_fail || panic "Dropping to a shell." wait_for_udev - Hypothetical explanation: mountroot_fail finds a degraded RAID-1 array and starts it with one disk, creating device /dev/md0. The function ends. Next, the 'local' script tries to mount the root partition, but udev did not yet have time to detect the partitions and create the corresponding devices md0p1 and md0p1, and change the links in /dev/disk/by-uuid to these detected partitions. The links in /dev/disk/by-uuid still point to /dev/sda[12], which are locked by mdadm for md0. The added wait_for_udev lets udev find the partitions md0p1 and md0p2 and change the links in /dev/disk/by-uuid before trying to mount the root partition. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/942106 Title: software raid doesn't assemble before mount on boot To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mdadm/+bug/942106/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

12.04.1 with all updated.This bug still affects me too! My setup is the following: 4 LUKS encrypted partitions with mdadm RAID5 on top. The reason I encrypted first and then added them into the array was based on performance: 4 threads doing encryption/decryption instead of just 1. The max speed of this array vs Raid5 first, encrypt later is 169 MB/s vs 90 MB/s. This setup used to work perfectly in 9.10, but stopped working in 12.04. mdadm always thinks the array is degraded.

[Bug 942106] Re: software raid doesn't assemble before mount on boot
@Doug Jones (djsdl) This bug report is not meant to fix *all* issues with raid, with respect to booting. Previously booting would drop into initramfs too quickly, now we wait for udev events to be processed and then we drop to initramfs. So this particular bug fix is fixing just this issue. You do not describe dropping into initramfs & assembling arrays by hand, nor having RAID on root. So I do not believe that you are solely affected by this bug, but other bugs as well. So while not perfect, this -proposed upgrade does not regress any further for you (e.g. some raids were not assembled before, and still are not assembled), but it does improve the situation for others. Did you see https://wiki.ubuntu.com/ReliableRaid specification and bugs linked from there? You may be familiar / affected by them. I would be interested to see your setup, e.g. `$ sudo apport mdadm ` should create a bug with all relevant system info attached. ** Tags removed: verification-needed ** Tags added: verification-done -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/942106 Title: software raid doesn't assemble before mount on boot To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mdadm/+bug/942106/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 942106] Re: software raid doesn't assemble before mount on boot
This does NOT fix this issue for me. My system still boots up with some RAID arrays not running. Every single time. This system has six SATA drives on two controllers. It contains seven RAID arrays, a mix of RAID 1, RAID 10, and RAID 6; all are listed in fstab. Some use 0.90.0 metadata and some use 1.2 metadata. The root filesystem is not on a RAID array (at least not any more, I got tired of that REAL fast) but everything else (including /boot and all swap) is on RAID. BOOT_DEGRADED is set. All partitions are GPT. Not using LUKS or LVM. All drives are 2TB and by various manufacturers, and I suspect some have 512B physical sectors and some have 2KB sectors. This is an AMD64 system with 8GB RAM. This system has had about four different versions of Ubuntu on it, and has had multiple RAID arrays on it from the beginning. (This is why some of the arrays are still using 0.90.0 metadata.) RAID worked fine until the system was upgraded to Oneiric early in 2012 (no, it did not start with Precise). I have carefully tested the system every time an updated kernel or mdadm has appeared, since the problem started with Oneiric. The behavior has gradually improved over the last several months. This latest version of mdadm (3.2.5) did not result in significant improvement; have rebooted four times since then and the behavior is consistent. When the problem first started, on Oneiric, I had the root file system on RAID. This was unpleasant. I stopped using the system for a while, as I had another one running Maverick. When I noticed some discussion of possibly related bugs on the Linux RAID list (I've been lurking there for years) I decided to test the system some more. By then Precise was out, so I upgraded. That did not help. Eventually I backed up all data onto another system and did a clean install of Precise on a non-RAID partition, which made the system tolerable. I left /boot on a RAID1 array (on all six drives), but that does not prevent the system from booting even if /boot does not start during Ubuntu startup (I assume because GRUB can find /boot even if Ubuntu later can't). I started taking detailed notes in May (seven cramped pages so far). Have rebooted 23 times since then. On every boot, exactly two arrays did not start. Which arrays they were, varied from boot to boot; could be any of the arrays. No apparent correlation with metadata type or RAID level. This mdadm 3.2.5 is the first time I have resorted to doing a forced upgrade from -proposed; before, I always just waited for a regular update. The most significant improvements happened with earlier regular updates. It has been a while since I had to wait for a degraded array to resync, or manually re-attach a component (usually a spare) that had become detached, or drop to the command line to zero a superblock before reattaching a component. It has been a while since an array containing swap has failed to start. This issue has now become little more than an annoyance. I can now boot, wait for first array to not start, hit S, wait for the second, hit S, wait for the login screen, log in, wait for Unity desktop, start Disk Utility, manually start the two arrays that didn't start, then check all the other arrays to see if anything else has happened. Takes about five minutes. But I am still annoyed. If you want to replicate this behavior consistently, get yourself seven arrays. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/942106 Title: software raid doesn't assemble before mount on boot To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mdadm/+bug/942106/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I only use the mdadm array for data, i.e. I don't boot from them. I was originally subscribed to one of the duplicate bugs. The problem I had was that booting would stop with a message about the disks not being ready and the option to 'S'kip or 'M'anual. To work round this I added the `noauto` option to the /etc/fstab entry for the array and called mount(8) in /etc/rc.local My testing of this fix has simply being to remove the `noauto` option from /etc/fstab and the call to mount(8) in /etc/rc.local.

[Bug 942106] Re: software raid doesn't assemble before mount on boot
This bug was fixed in the package mdadm - 3.2.5-1ubuntu1 --- mdadm (3.2.5-1ubuntu1) quantal; urgency=low * Merge from Debian testing. (LP: #920324) Remaining changes: - Call checks in local-premount to avoid race condition with udev and opening a degraded array. - d/initramfs/mdadm-functions: Record in /run when boot-degraded question has been asked so that it is only asked once - pass --test to mdadm to enable result codes for degraded arrays. - debian/control: we need udev and util-linux in the right version. We also remove the build dependency from quilt and docbook-to-man as both are not used in Ubuntus mdadm. - debian/initramfs/hook: kept the Ubuntus version for handling the absence of active raid arrays in /etc/mdadm/mdadm.conf - debian/initramfs/script.local-top.DEBIAN, debian/mdadm-startall, debian/mdadm.raid.DEBIAN: removed. udev does its job now instead. - debian/mdadm-startall.sgml, debian/mdadm-startall.8: documentation of unused startall script - debian/mdadm.config, debian/mdadm.postinst - let udev do the handling instead. Resolved merge conflict by keeping Ubuntu's version. - debian/mdadm.postinst, debian/mdadm.config, initramfs/init-premount: boot-degraded enablement; maintain udev starting of RAID devices; init-premount hook script for the initramfs, to provide information at boot - debian/mkconf.in is the older mkconf. Kept the Ubuntu version. - debian/rules: Kept Ubuntus version for installing apport hooks, not installing un-used startall script. - debian/install-rc, check.d/_numbers, check.d/root_on_raid: Ubuntu partman installer changes - debian/presubj: Dropped this unused bug reporting file. Instead use source_mdadm.py act as an apport hook for bug handling. - d/p/debian-changes-3.1.4-1+8efb9d1ubuntu4: mdadm udev rule incrementally adds mdadm member when detected. Starting such an array in degraded mode is possible by mdadm -IRs. Using mdadm -ARs without stopping the array first does nothing when no mdarray-unassociated device is available. Using mdadm -IRs to start a previously partially assembled array through incremental mode. Keeping the mdadm -ARs for assembling arrays which were for some reason not assembled through incremental mode (i.e through mdadm's udev rule). * Additional Ubuntu changes: - debian/initramfs/local-premount: add call wait_for_udev to wait a little longer for RAID devices to appear (LP: #942106) * Dropped Ubuntu changes: - Build udeb with -O2 on ppc64, working around a link error. Builds fine without it on debian. - rename debian/mdadm.vol_id.udev to debian/mdadm.mdadm-blkid.udev so that the rules file ends up with a more reasonable name. debian/rules changes for adding ubuntu's udev rule corresponding to mdadm. As we are now using 'upstream' udev rules see 3.2.3-2ubuntu2. * Changes to Ubuntu changes: - debian/source_mdadm.py: make apport hook python 2 and 3 compatible (LP: #1013171). * New upstream release closes this bugs: - mdadm --detail --scan segfaults during update-initramfs (LP: #969384) -- Dmitrijs LedkovsFri, 15 Jun 2012 15:31:59 +0100 ** Changed in: mdadm (Ubuntu Quantal) Status: Confirmed => Fix Released -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/942106 Title: software raid doesn't assemble before mount on boot To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mdadm/+bug/942106/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 942106] Re: software raid doesn't assemble before mount on boot
The Debian mdadm scripts uses an explicit assembly in initramfs and seems to offer a lot more of fallback logic than we currently have. Also, udev settle makes you wait for devices that might not be necessary for boot. The full Debian mdadm initramfs logic seems to be a good alternative to the current logic. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/942106 Title: software raid doesn't assemble before mount on boot To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mdadm/+bug/942106/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Setting multiple md arrays seems to be a good way to reproduce this bug (see #682019). Or maybe just a big md array. After that, it's just a timing issue.

I'm still trying to reproduce/test this bug. By the looks of it, adding wait_for_udev call is sensible. On the other hand, udev incremental assembly has been disabled in a debian patch, which we inherited.
