Hi, I am testing GlusterFS 3.1.2 on Ubuntu with NFS support. After a few weeks of error-free working, unfortunately GlusterFS crashed. Maybe this is bug in newest version therefore I am putting here logs to diagnose (maybe some guru from Gluster Team can help here). If more details is needed please let me know. Below logs: [2011-02-16 16:14:09.924988] I [afr-common.c:613:afr_lookup_self_heal_check] test_volume-replicate-2: size differs for /onerepo/50cab8255b4c3a6ee377baf45fc61 e7c7cab6b32 [2011-02-16
