This message is a reminder that Fedora 17 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 17. It is Fedora's policy to close all bug reports from releases that are no longer maintained.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 '17'. 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 17'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 17 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, you are encouraged change the 'version' to a later Fedora version prior to Fedora 17's end of life. 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. It also happens in F20 systemd-208-9.fc20.x86_64 kernel-3.12.5-301.fc20.x86_64 libmount-2.24-2.fc20.x86_64 with a 10 sec time out, after the 10 seconds I tried to access it, I get these messages: systemd: Timed out waiting for device dev-sdb1.device. systemd: Dependency failed for /mnt/backup. I can't reproduce this. systemd-208-28.fc20.x86_64 If this is still a problem for anybody, please, reopen this bugzilla with and attach a reproducer. |
Created attachment 622907 [details] strace log Description of problem: I have some records in fstab describing devices which can be absent (HDD not plugged). I enabled automount for them and expected just a file open error if any application tries to access file on an absent device. Actual behaviour is that application freezes forever (more than systemd mount timeout). Example record in fstab: UUID=0E64-0E6B /mnt/test vfat x-systemd.automount,x-systemd.device-timeout=7,rw,nosuid,nodev,noexec,user,utf8,shortname=mixed 0 0 Strace of `/bin/ls /mnt/test` attached, it hangs at stat("/mnt/test") for that case. Version-Release number of selected component (if applicable): kernel-3.5.4-2.fc17.x86_64 systemd-44-17.fc17.x86_64 libmount-2.21.2-2.fc17.x86_64 How reproducible: Always. Might be related: RHBZ#859374
