From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.12) Gecko/20050922 Fedora/1.0.7-1.1.fc4 Firefox/1.0.7 Description of problem: After using Konqueror, my vfat files system becomes read only. Details are below. I have an internal hard drive, /dev/hdb1, mounted at /local at startup. Output from the mount command immediately after startup: (Logged in as root.) [root@localhost program files]# mount /dev/mapper/VolGroup00-LogVol00 on / type ext3 (rw) /dev/proc on /proc type proc (rw) /dev/sys on /sys type sysfs (rw) /dev/devpts on /dev/pts type devpts (rw,gid=5,mode=620) /dev/hda2 on /boot type ext3 (rw) /dev/shm on /dev/shm type tmpfs (rw) /dev/hdb1 on /local type vfat (rw) ---THIS IS THE DRIVE none on /proc/sys/fs/binfmt_misc type binfmt_misc (rw) sunrpc on /var/lib/nfs/rpc_pipefs type rpc_pipefs (rw) automount(pid2268) on /misc type autofs (rw,fd=4,pgrp=2268,minproto=2,maxproto=4) automount(pid2294) on /net type autofs (rw,fd=4,pgrp=2294,minproto=2,maxproto=4) Initially, the drive is read/write. See test output below: [root@localhost ~]# cd "/local/program files" [root@localhost program files]# ls MUSICMATCH [root@localhost program files]# touch test [root@localhost program files]# ls MUSICMATCH test [root@localhost program files]# rm test rm: remove regular empty file `test'? y Next, I launch Konqueror by clicking the "File Manager - Super User Mode" icon. I browse to the /local directory then close the window. After that, the drive is read only, see test output below: [root@localhost program files]# touch test touch: cannot touch `test': Read-only file system Additionally, I can not unmount the drive. See message below: [root@localhost program files]# umount /dev/hdb1 umount: /local: device is busy umount: /local: device is busy [root@localhost program files]# Also note, it still appears that the drive is rw: [root@localhost program files]# mount /dev/mapper/VolGroup00-LogVol00 on / type ext3 (rw) /dev/proc on /proc type proc (rw) /dev/sys on /sys type sysfs (rw) /dev/devpts on /dev/pts type devpts (rw,gid=5,mode=620) /dev/hda2 on /boot type ext3 (rw) /dev/shm on /dev/shm type tmpfs (rw) /dev/hdb1 on /local type vfat (rw) ---THIS DID NOT CHANGE none on /proc/sys/fs/binfmt_misc type binfmt_misc (rw) sunrpc on /var/lib/nfs/rpc_pipefs type rpc_pipefs (rw) automount(pid2268) on /misc type autofs (rw,fd=4,pgrp=2268,minproto=2,maxproto=4) automount(pid2294) on /net type autofs (rw,fd=4,pgrp=2294,minproto=2,maxproto=4) At this point, I have to log out of KDE and then bring it back up. I can then unmount the drive and mount it again as read/write. Thanks. Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1.See above Actual Results: [root@localhost program files]# touch test touch: cannot touch `test': Read-only file system Expected Results: [root@localhost program files]# touch test [root@localhost program files]# ls MUSICMATCH test Additional info:
Could you attach dmesg from when the fs becomes ro. Also fuser -mv /local will reveal the open processes. You will need to cd out of the directory and close any browser windows in the mount before umount will work.
The same problem here, but I use gnome and the problem also appears if I create/delete files from a tty. So I think it is not a kdebase bug, I propose to change it to kernel bug. I have to remount rw the volume after each create/remove file, but i do not have the "device busy" problem. I obtain an error message when running from a tty FAT: Filesystem panic (dev sda6) fat_free_clusters: deleting FAT entry beyond EOF File system has been set read-only Although the mount comand shows it as read-write. An fsck.vfat shows [root@mychabol ~]# fsck.vfat -n /dev/sda6 dosfsck 2.11, 12 Mar 2005, FAT32, LFN /Recycled/De9.micasa Contains a free cluster (68037). Assuming EOF. /Recycled/De9.micasa File size is 73 bytes, cluster chain length is 0 bytes. Truncating file to 0 bytes. Reclaimed 2 unused clusters (8192 bytes). Free cluster summary wrong (565964 vs. really 633269) So there is a problem, the clusters are not really free when deleting files.
it looks like a bug in kernel
Does this still happen in FC5 ?
The first time it happened to me I was using FC5, but now I am unable to reproduce the problem.
A new kernel update has been released (Version: 2.6.18-1.2200.fc5) based upon a new upstream kernel release. Please retest against this new kernel, as a large number of patches go into each upstream release, possibly including changes that may address this problem. This bug has been placed in NEEDINFO state. Due to the large volume of inactive bugs in bugzilla, if this bug is still in this state in two weeks time, it will be closed. Should this bug still be relevant after this period, the reporter can reopen the bug at any time. Any other users on the Cc: list of this bug can request that the bug be reopened by adding a comment to the bug. In the last few updates, some users upgrading from FC4->FC5 have reported that installing a kernel update has left their systems unbootable. If you have been affected by this problem please check you only have one version of device-mapper & lvm2 installed. See bug 207474 for further details. If this bug is a problem preventing you from installing the release this version is filed against, please see bug 169613. If this bug has been fixed, but you are now experiencing a different problem, please file a separate bug for the new problem. Thank you.
(this is a mass-close to kernel bugs in NEEDINFO state) As indicated previously there has been no update on the progress of this bug therefore I am closing it as INSUFFICIENT_DATA. Please re-open if the issue still occurs for you and I will try to assist in its resolution. Thank you for taking the time to report the initial bug. If you believe that this bug was closed in error, please feel free to reopen this bug.
