When the import happens, it locks the filesystem, "df" hangs and unable to use the filesystem. Once the import completes, the filesystem is back to normal and read/write works fine. The same doesnt happen in Solaris/OpenIndiana. # uname -an FreeBSD hostname 9.0-RELEASE FreeBSD 9.0-RELEASE #0: Tue Jan 3 07:46:30 UTC 2012 root@farrell.cse.buffalo.edu:/ usr/obj/usr/src/sys/GENERIC amd64 Zfs ver: 28 Any inputs would be helpful. Is there any way to overcome this freeze ? Regards, Ram
