No reply... Next I asked this on freebsd-fs. No reply... So maybe there? After the latest -current install, I'm trying the following command sequence (test_file has 30000 bytes or more): cd / mkdir test mount -t null /test /mnt cp test_file /mnt/test.bad cp test_file /test/test.ok diff /test/test.bad /test/test.ok ... Yes, files are the same - great reboot ... Login diff /test/test.bad /test/test.ok ... Oh no! Files differ! Lengths are the same, but content of /test/test.bad (file copied via nullfs) is partially zeroed! Does anybody use nullfs layer? Is this only my problem on my box? (Problem occurs if nullfs is mounted on root ffs.) -------------------------------------------------------------------------- Rudolf Cejka E-mail: xcejka00@dcse.fee.vutbr.cz Technical University of Brno, Faculty of El.
