I have a FreeBSD 10.1-RELEASE-p13 machine on an air-gapped network. When I perform an 'ls -l' on a particular directory (with ~5 files), the ls process freezes and does not return. kill -9 and closing the shell doesn't make the process go away either. Samba has some of these files open and I suspect the samba processes are stuck too. Something similar happened a month ago that required a "pull the plug" reboot as the FS was in such a state that it would not unmount. Please [quickly -- i'll probably have to reboot soon] let me know if you would like to see any debug output. Last line of 'truss ls -l' (before the freeze) is: lpathconf(...) = 1 (0x1) The frozen 'ls -l' process is in the DX+ state. zpool status is happy The pool has a 24 TB capacity. The problem FS is using 1TB with ~1.5 million files. Chris
