[Bug 442495] Re: mountall hangs in case of inconsistent /etc/fstab
mountall is obviously unable to deal with an fstab with the wrong UUID in it. The case of showing a message on screen and allowing to cancel is covered by a different bug# (and is already done, pending a usplash bug fix) ** Changed in: mountall (Ubuntu) Status: Incomplete => Invalid -- mountall hangs in case of inconsistent /etc/fstab https://bugs.launchpad.net/bugs/442495 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
Re: [Bug 442495] Re: mountall hangs in case of inconsistent /etc/fstab
Fortunately, all my partitions in /dev/disks/by-uuid reappeared again. So I cannot reproduce the initial problem. But you can reproduce the hanging boot easily by creating a /home mount with a wrong uuid in /etc/fstab. I have tested this approach (intentionally giving the wrong uuid of my /home partition) with mountall versions 0.2.2 as it is in karmic at the time of writing this and 0.2.2~boot2 as published in ppa. In both cases the boot hangs and cannot be interrupted, neither with ctrl-c nor with sysreq-e. Sysreq-e kills udev but not mountall anymore. Uninstalling cryptsetup so that ctrl-c might work does not help either. You need either a live-cd or another boot-partition to get the system running again. Attached is the output of mountall --debug of 0.2.2 with my correct and incorrect /etc/fstab before the reboot as requested. ** Attachment added: "m-0.22.log" http://launchpadlibrarian.net/33726055/m-0.22.log ** Attachment added: "m-0.22-bad.log" http://launchpadlibrarian.net/33726056/m-0.22-bad.log -- mountall hangs in case of inconsistent /etc/fstab https://bugs.launchpad.net/bugs/442495 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Daniel, please open a separate bug report on cryptsetup for your issue. Unfortunately, I think mountall itself is behaving correctly in your case - you have this cryptsetup device bind-mounted to /opt, and /opt is a FHS filesystem which, if absent at boot, could causes services to fail to start (since packages in /opt may have init scripts in /etc/rc2.d that expect the files to be available). So in the general case, *not* waiting for this filesystem to be present before proceeding with the boot could cause serious boot-time instabilities. (This is distinct from bug #448267, where I argue that we should not be waiting for /srv before entering runlevel 2 because nothing in /srv should be a dependency of the system boot.) So your underlying problem is that cryptsetup isn't correctly setting up your devices, but that it should be doing so. There's no evidence that this is related to the problem ooops is reporting here. -- mountall hangs in case of inconsistent /etc/fstab https://bugs.launchpad.net/bugs/442495 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 442495] Re: mountall hangs in case of inconsistent /etc/fstab
Sorry about the issues with the previous PPA versions, as usual things worked just fine when I tested it in the various rigs I have here - of course it flatly failed when installed on normal systems because I hadn't actually tested that ;) I've uploaded a new ~boot4 version, this one feels much better (and I'm running it on my laptop now :p) As before, after installing the package but *before* you reboot, please run with --debug and attach the log to the bug - then after rebooting, let me know how it works out. Thanks for all your help with testing, this is a big change and it's good to know that it's now working for 95% of people and your help getting it work for the final 5% is greatly appreciated! -- mountall hangs in case of inconsistent /etc/fstab https://bugs.launchpad.net/bugs/442495 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
Re: [Bug 442495] Re: mountall hangs in case of inconsistent /etc/fstab
Attached is the output before reboot with karmic and ppa mountall. Note that mountall with karmic mountall does not terminate. I had to stop it with a ctrl-c. What is attached is the output until that point. The boot with new mountall itself hangs and cannot be interrupted by sysreq-e. Thus I was not able to debug. Actually it even hangs in case I use the /dev/sda5 in fstab. So I have no idea why and where it hangs. Actually, I see now all the disks in /dev/disk/by-uuid. I have no idea what changed in the system. I can do more tests in about a week.

Marking as Triaged, since I can confirm it (via other circumstances). My comments above are not very relevant: I can imagine that given a invalid UUID in fstab, mountall would hang forever. ** Changed in: mountall (Ubuntu) Importance: Undecided => Medium ** Changed in: mountall (Ubuntu) Status: Incomplete => Triaged -- mountall hangs in case of inconsistent /etc/fstab https://bugs.launchpad.net/bugs/442495 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 442495] Re: mountall hangs in case of inconsistent /etc/fstab
The devices not being mounted are cryptsetup/luks partitions, which are listed in /etc/crypttab, using a key-file. I guess the problem is that mountall is waiting for them to become available, but they never do. So, after all, I think the initial bug report is related, as mountall should fail/not hang with invalid UUIDs, but my problem goes one step further: the cryptsetup devices are not being setup properly anymore. Note: the root device is mounted/opened correctly using cryptsetup via passphrase. -- mountall hangs in case of inconsistent /etc/fstab https://bugs.launchpad.net/bugs/442495 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
