Description of problem: OS Version: Fedora 16 Installation Medium: netinst ISO x86_64 KDE-spin Problem Description: I've chosen for installation in the root "/" (/ dev/sda3) file system btrfs. I have to subvolume with the name VOL-ROOT created. # btrfs subvolume list / ID 256 top level 5 path VOL-ROOT After installation, I was able to register without problems to the KDE desktop. Now I have created another subvolume for the home directory (VOL-HOME). That mount point, I'm in the /etc/fstab. # btrfs subvolume list / ID 256 top level 5 path VOL-ROOT ID 257 top level 5 path VOL-HOME # cat /etc/fstab UUID=5d1fb49b-758a-4cfe-aa56-ba4f9707ddf6 / btrfs defaults,subvolid=256 1 1 UUID=5d1fb49b-758a-4cfe-aa56-ba4f9707ddf6 /home btrfs defaults,subvolid=257 1 1 UUID=ab7e61f3-2a73-43d4-98f3-75126c0e90f6 /boot ext4 defaults 1 2 UUID=f6a58a92-9b3f-4502-a3b0-6260b0013e9c swap swap defaults 0 0 The user directories from the original /home I moved into the new /home in the subvolume HOME-VOL. After a reboot I could not log me KDE desktop. The following error message was displayed on the screen: First dialog box: Can not enter home directory. Using /. Second dialog box: No write access to $ HOME directory (/). KDE is unable to start. Third dialog: Could not start ksmserver. In the file /var/log/messages contains the following error message: Nov 13:38:11 fedorabox kdm: :0 '[898]: Cannot chdir to michael's home /home/michael: Permission denied The file permissions on /home but are correct: # ls -l /home drwxr-xr-x. 1 root root 82 11. Nov 12:49 /home drwx------. 1 michael michael 554 11. Nov 13:19 michael Why can I not log on KDE desktop? How reproducible: any time If I were doing anything in the home directory irreversibly, ie the /home directory from the subvolume subvolume VOL-VOL-HOME back to ROOT move I can log back on KDE. Incidentally, a login to the text console (tty) is always possible. My guess is that if the problem is handling the subvolume btrfs or on KDE itself. Regards Michael Singer
Adjustment because of spelling errors (third from last paragraph): [...] If I do the whole reverse, ie the / home (from subvolume VOL-HOME) back into the subvolume VOL ROOT move me I can log into the KDE desktop. [...]
This message is a reminder that Fedora 16 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 16. It is Fedora's policy to close all bug reports from releases that are no longer maintained.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 '16'. 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 16'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 16 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 to click on "Clone This Bug" and open it against that version of Fedora. 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 16 changed to end-of-life (EOL) status on 2013-02-12. Fedora 16 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.
