Description

This is caused as we use memory as the backing store for changes to the live system. Unfortunately, I don't know of a good way to really detect (to avoid or warn)... longer term, we want to be able to have the changes persist with backing on disk which would help with the problem. Not a huge deal; sort of an edge case, obviously. Thought it was worth recording, though, in case it was an easy fix. I'm hitting this on the RTM version of FC9 as well. I'm using a 250MB overlay and it appears that once this space is used, I hit this bug as well. This renders my usb flash drive unbootable and is easy to repro. Are there any suggestions on how to either avoid this (besides the obvious dont use all the overlay) or recover the flash drive? There should be a mechanism to save a user from bricking the flash drive by running out of space. If it would help, I can provide log files, ect. Please contact me if this would help. *** Bug 443475 has been marked as a duplicate of this bug. *** For Fedora 10, I definitely want to get some sort of "view" into what the available free space in the overlay looks like as well as give more intelligent indicators of things going bad. (For my own remembering as much as anything) We can get information on how much of the overlay is used with 'dmsetup status live-rw', the fourth field gives us UsedBlocks/TotalBlocks So some thoughts on what we could do * Poll at some interval on what the used percentage is. When you get to a certain amount (80%, 90%?), give a notification to the user. Tricky as polling sucks and the polling has to be done as root. * Shrink the rootfs based on the size of the snapshot at boot time. This wouldn't be 100% as snapshot blocks don't get reused, but it might help. But this is a pain as we can't shrink filesystems when they're unmounted * Switch to using the minimal rootfs always and then resize it based on the snapshot size. Same caveats as above, but seems a little more plausible to implement I sort of like the second and third options as then we could just rely on fixing the desktop notification of the problem in general but it still doesn't end up "fully" fixing things due to dm-snapshot not reusing blocks. *** Bug 450097 has been marked as a duplicate of this bug. *** Okay, after a bit of hacking and trying different things, I'm pretty convinced that the only way we can really get to do anything reasonable here is by having something more than dm-snapshot to use as our overlay like, eg, unionfs. If we were able to use unionfs, then we'd just get -ENOSPC when out of space and it would just be a matter of the normal reporting (and checking via statfs64) of that as opposed to trying to deal with the weird cases that dm-snapshot bubbles up Reassigning to kernel for that This message is a reminder that Fedora 8 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 8. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '8'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 8's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 8 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora please change the 'version' of this bug to the applicable version. If you are unable to change the version, please add a comment here and someone will do it for you. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping Fedora 8 changed to end-of-life (EOL) status on 2009-01-07. Fedora 8 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. Thank you for reporting this bug and we are sorry it could not be fixed. |
