<div dir="ltr">Hi, I'm probably hitting some bug in F11. I've created the lcktest directory, and "date > lcktest/date-file" to create a simple file inside. Repeated this on a ext3 and a ext4 file-system. Now, this works fine on ext3, but fails on ext4. I tried the same setup on another F11 machine that was upgraded from F10 and hit the same locking bug. The behaviour is below, and a full 'strace -f' in case of ext4 is at <a href="http://www.fpaste.org/sZXa/">http://www.fpaste.org/sZXa/</a> ********** On a EXT3 file-system [me@matrix ~]$ unison -ui text -batch unitest/ ssh://dev@cairo//tmp/unitest/ Contacting server...
