[Bug 1431650] Re: Multipath devices take long to initialize during initramfs
** Description changed: + [Impact] + Impacts any user of multipath, regardless of release. Users who do not currently see issues may see them on upgrade to a newer version of systemd/udev. + + [Test case] + See below. Test case can be summarized as "boot on a multipath system". + + [Regression potential] + This changes the behavior on locking devices for multipath, to avoid a deadlock with udev. Since this changes the locking behavior of multipath this may also affect other scripts or applications depending on multipath doing an exclusive lock, so scripts or applications could fail because they acquired a lock on the devices prematurely, before multipath was finished. In most cases this shouldn't happen, as it should be limited to an isolated multipath step in the boot process (in initramfs). + + --- + Problem: during initramfs, multipath devices takes long to initialize (~30 seconds?)

May you describe the issues you're seeing?
I guess I have hit more than a few so far.
Specifically, check bug 1429327 ('multipath' runs *before* all disks
show up), and bug 1432062 (udev rules fail w/ disk-names w/ spaces when
user_friendly_names isn't set).

I see delays in the devices being detected, which means after running through the initramfs scripts and other startup scripts, the installed system will come up using /dev/sdb1 (for example) rather than the equivalent device mapper device, and no swap.

[Bug 1431650] Re: Multipath devices take long to initialize during initramfs
Hi Mathieu, I did some research for the commit mentioned in comment #10. Its description clarifies (how/why) it solves this problem, and even others we would probably hit later (e.g., after booting, SCSI disks added/removed re-trigerring udev rules, and then involving multipathd). It's been written by a multipath/enterprise hardware guy for the suse distros. I see it in opensuse [1], with a patch named after 'sles12', which also names the branch in his github repo [2]. It looks good to go, combined with another fix applied to the initramfs script (the udev settle thing we talked about, but on a slightly different place). Patch attached. With it applied, the udev timeout/killing disappears as expected, and with the earlier 'udevadm settle' call in place, so disappears the random dm ioctl() failures (race condition w/ multipath in udev rules): device-mapper: create ioctl on mpathX-partY failed: Device or resource busy create/reload failed on mpathX-partY In summary, the attached patch restores event-based multipath discovery.. and we no longer need to remove the 95-multipath.rules from initramfs.

Updated replies to earlier comments: comment #6 > I think this all goes back to multipath-tools updates that would help a whole > lot; but they may be a little too intrusive past feature freeze -- I'm > looking into just updating the udev rules now. Just to clarify/respond to that (earlier than patch) comment with regards to the patch attached. Given that the patch introduces only 2 changes, which are minimal/small (and one may sometimes be a nop), and is totally contained in multipath stuff, I think it'd be OK to get it in.

Well, not necessarily. The swap issue is the same as the rootfs one-- at some point multipath times out, and other init jobs would also timeout trying to bring up the swap (which can't be identified from the UUID) whereas the rootfs got brought up on a single path using the UUID.

> Well, not necessarily. The swap issue is the same as the rootfs one Ah, yes, you're right. I was thinking with the assumption that the workaround/patch for the timeout was in place. Indeed, if it's not in place, there'll be no swap nor anything multipath'ed at all. In the particular case the workaround/patch is applied, what I've seen is a job waiting/timing out for the swap device (now) incorrectly specified in /etc/fstab.

[Bug 1431650] Re: Multipath devices take long to initialize during initramfs
This bug was fixed in the package multipath-tools - 0.4.9-3ubuntu11 --- multipath-tools (0.4.9-3ubuntu11) vivid; urgency=medium [ Mauricio Faria de Oliveira ] * Added debian/patches/0015-shared-lock-for-udev.patch (LP: #1431650) * debian/initramfs/local-top: wait for udev to settle before running 'multipath' in order to avoid race condition on device-mapper calls. [ Mathieu Trudel-Lapierre ] * Drop scsi_wait_scan from the multipath initramfs script: that module no longer exists. -- Mathieu Trudel-LapierreMon, 23 Mar 2015 14:56:37 -0400 ** Changed in: multipath-tools (Ubuntu) Status: In Progress => Fix Released -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to multipath-tools in Ubuntu. https://bugs.launchpad.net/bugs/1431650 Title: Multipath devices take long to initialize during initramfs To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/multipath-tools/+bug/1431650/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs

"This bug was fixed in the package multipath-tools - 0.4.9-3ubuntu11" I have 0.4.9-3ubuntu12 but it still occurs to me. 5 minutes boot time :( So how to fix it ? -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to multipath-tools in Ubuntu. https://bugs.launchpad.net/bugs/1431650 Title: Multipath devices take long to initialize during initramfs To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/multipath-tools/+bug/1431650/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs

@xirius I'm debugging a similar issue that happens w/ hundreds of paths. They're so many that the boot just takes a really long time.

@mauricfo Sorry for the late response. 31 paths are expected on mine and it takes ages to boot. -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to multipath-tools in Ubuntu. https://bugs.launchpad.net/bugs/1431650 Title: Multipath devices take long to initialize during initramfs To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/multipath-tools/+bug/1431650/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
[Bug 1431650] Re: Multipath devices take long to initialize during initramfs
@xirius Well, I guess that's a different problem. Sorry, I can't help w/ debugging that, but I'd suggest you to track/compare boot times w/ a increasing number of paths, or from different adapters/storage systems, until you rule out the slow-down factor. -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to multipath-tools in Ubuntu. https://bugs.launchpad.net/bugs/1431650 Title: Multipath devices take long to initialize during initramfs To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/multipath-tools/+bug/1431650/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
