Before completing the branch management (adding, in your case), all accesses to the aufs will be blocked. So we should investigate "why did adding a branch block" before "why 'find' freeze and 'lsof' got crazy". > What more info should I provide in order for you to debug this? Thank you The kernel version and pathces are important. Also these info are important too. - /proc/mounts (instead of the output of mount(8)) - /sys/module/aufs/* - /sys/fs/aufs/* (if you have them) - /debug/aufs/* (if you have them) - linux kernel version if your kernel is not plain, for example modified by distributor, the url where i can download its source is necessary too. - aufs version which was printed at loading the module or booting the system, instead of the date you downloaded. - configuration (define/undefine CONFIG_AUFS_xxx) - kernel configuration or /proc/config.gz (if you have it) J.
