Yesterday I encountered an on-the-fly corruption of my /home filesystem. It worked perfectly one second, the next I hit these nice errors:

Nov 21 16:37:23 precious kernel: Please umount the filesystem, and rectify the problem(s)

Doing an unmount/remount didn't solve it, i had to run xfs_repair on the filesystem to get it back to 'work', which caused me to lose 
a lot of stuff. (thank <deity> for backups.) 

Any idea what can cause this?

Thanks,

Jan
