Public bug reported: Binary package hint: devicekit-disks
After upgrading to Karmic, the script I was using to back up my data (to an NTFS formatted external hard drive) no longer works (my ext3 formatted external hard drive still works fine). The disk mounts with the following options when I plug it in (from mount -l): /dev/sdb1 on /media/MEDIABOX type vfat (rw,nosuid,nodev,uhelper=devkit,uid=1000,gid=1000,shortname=mixed,dmask=0077,utf8=1,flush) [MEDIABOX] I thought it mounted as ntfs previously, but my recollection on that point may be wrong. I can't get it to mount as ntfs now. The following problems result when I run the rsync command that worked previously: 1. rsync tries to copy far more files than it should (possibly too many even if --size-only is set; if --size-only is not set, it tries to copy basically everything, even though I am using --modify-window=1) 2. rsync yields the following errors, even if run with sudo: rsync: mkstemp "[filename on external HD]" failed: Read-only file system (30) rsync: failed to set times on "[filename on external HD]": Read-only file system (30) [... many, many instances of those same errors ...] 3. Looking at syslog yields the following: Nov 7 14:51:28 system42 kernel: [100893.332080] FAT: Filesystem error (dev sdb1) Nov 7 14:51:28 system42 kernel: [100893.332103] fat_free_clusters: deleting FAT entry beyond EOF Nov 7 14:51:28 system42 kernel: [100893.332112] File system has been set read-only That looks troublingly like a bug described here: http://www.osnews.com/story/9681/The_vfat_file_system_and_Linux/page3/ Troubling because that article claims: Under Linux Kernel 2.4.x., a limit of the cluster data type results in data loss, as soon as the vfat file system holds around 130GB. In Kernel 2.6.x., this problem was - rather accidently - solved... (The drive I'm using is 500GB and mostly full, 435 GB used.) And I am indeed running a 2.6 kernel: $ uname -r 2.6.31-14-generic So is this a regression of a kernel bug? The data on the disk hasn't been lost or corrupted as far as I can tell, though I don't really feel I can trust the backup files touched by rsync post upgrade (at least not until I can rerun it after this problem is fixed). Looking at the disk in nautilis confirms that it has indeed been set read-only. If I unmount and remove the disk, then plug it in again, it remounts, and I can again read and write files. Running rsync again still results in the same problem. Submitting this to devicekit-disks because I guess it has something to do with the disk mounting differently in Karmic than it did in Intrepid... although the problem could well lie elsewhere.
