[Bug 1311987] Re: deploy-ironic ramdisks do not boot: Failed to execute /init (error -28)
subair, Can you open a new bug with a full description of the problem you are having, including the steps you took to get there so we can reproduce? This one is pretty specific to booting the deploy ramdisk on machines with less than 1GB of RAM. THANKS! ** Changed in: diskimage-builder Assignee: subair (muhsubair74) = (unassigned) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1311987 Title: deploy-ironic ramdisks do not boot: Failed to execute /init (error -28) To manage notifications about this bug go to: https://bugs.launchpad.net/devstack/+bug/1311987/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

So there's a later commit which adds a command-line option to force use of ramfs: commit 6e19eded3684dc184181093af3bff2ff440f5b53 Author: Rob Landley r...@landley.net Date: Wed Sep 11 14:26:13 2013 -0700 initmpfs: use initramfs if rootfstype= or root= specified Command line option rootfstype=ramfs to obtain old initramfs behavior, and use ramfs instead of tmpfs for stub when root= defined (for cosmetic reasons). Can you try adding rootfstype=ramfs to the kernel parameters and see if this works? Would you be able to do this for cases where you really need ramfs? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1311987 Title: deploy-ironic ramdisks do not boot: Failed to execute /init (error -28) To manage notifications about this bug go to: https://bugs.launchpad.net/diskimage-builder/+bug/1311987/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1311987] Re: deploy-ironic ramdisks do not boot: Failed to execute /init (error -28)
Thanks for the tip Seth.. That appears to work, thanks! I reached out to Rob and he pointed out that, when using tmpfs, the fs will fill up at 50% memory usage, so the ENOSPC is to be expected here. Now that the cause is known, I think we can get away with bumping the default and minimum required memory to 1GB for our ramdisks and we should be okay across the different kernel versions / rootfstypes. ** Also affects: devstack Importance: Undecided Status: New ** Changed in: linux (Ubuntu) Status: Confirmed = Invalid -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1311987 Title: deploy-ironic ramdisks do not boot: Failed to execute /init (error -28) To manage notifications about this bug go to: https://bugs.launchpad.net/devstack/+bug/1311987/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1311987] Re: deploy-ironic ramdisks do not boot: Failed to execute /init (error -28)
This turns out to be a kernel issue, either upstream or in Ubuntu. Bisected to the following, which was released in 3.12. commit 16203a7a9422315bc929461503e3a046459ea5ff Author: Rob Landley r...@landley.net Date: Wed Sep 11 14:26:12 2013 -0700 initmpfs: make rootfs use tmpfs when CONFIG_TMPFS enabled Conditionally call the appropriate fs_init function and fill_super functions. Add a use once guard to shmem_init() to simply succeed on a second call. (Note that IS_ENABLED() is a compile time constant so dead code elimination removes unused function calls when CONFIG_TMPFS is disabled.) I agree this is an edge case for tripleO but not so much for general Ironic usage, as admins should be free to declare nodes with as little memory as they want, and DIB produced deploy-ironic ramdisks should be expected to work. ** Also affects: linux (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1311987 Title: deploy-ironic ramdisks do not boot: Failed to execute /init (error -28) To manage notifications about this bug go to: https://bugs.launchpad.net/diskimage-builder/+bug/1311987/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
