Second timeout image after an even longer period of waiting
I noticed that after waiting for some more minutes I get more messages on my screen. They are all the same... so there are some more than in that image but I only posted the first ones. I didn't find any different messages.
Ok I got to boot my system by disabling many services I didn't need anyways and by removing the readahead file. I do not really know which of the changes worked around the problem but I guess it was disabling iscsi. 547 sudo systemctl disable lvm2-monitor.service 548 sudo systemctl disable lvm2-lvmetad.service 549 sudo systemctl disable sendmail.service 550 sudo systemctl disable sm-client.service 551 sudo systemctl disable bluetooth.service 552 sudo systemctl disable plymouth-read-write.service 553 sudo systemctl disable plymouth-start.service 554 sudo systemctl disable dmraid-activation.service 555 sudo systemctl disable livesys-late.service 556 sudo systemctl disable livesys.service 557 systemctl disable systemd-readahead-collect systemd-readahead-replay [...] 563 sudo mv /.readahead /noreadahead [...] 567 systemctl disable iscsid.socket 568 sudo systemctl disable iscsiuio.socket I will attach a log from the successful boot for completeness sake. Created attachment 992157 [details]
output of journalctl -b
After deactivating several services that are not needed anyways the system boots again. The log is from the first successful boot on the new kernel. I will leave it up to someone else to judge if the issue I encountered needs more investigation or is ok to be closed sorry for the time I made you guys spent on this issue.
Disabling all units related to readahead seems to solve the problem. The issue occurred on three out of five machines. All of them have a btrfs root file system. Readahead has been removed from systemd (release 219). Hence, the problem is already solved upstream. I would like to see a systemd patch for Fedora 21 which disables readahead as well. Are you using BTRFS for any of the default mounts? (Check /etc/fstab) If that is the case you are seeing bug 1187106. In https://bugzilla.redhat.com/attachment.cgi?id=992068, I can see: /dev/sdc3 on / type btrfs (rw,relatime,seclabel,ssd,space_cache) Thank you for the input. though I'm not entirely sure whether it is actually a duplicate of said bug 1187106 it is working for me now and seems to be only related to stale configs etc. I close the bug with "works for me" for now. |
