https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=201498 Bug ID: 201498 Summary: tar cannot archive some files on ZFS with compression. Product: Base System Version: 11.0-CURRENT Hardware: Any OS: Any Status: New Severity: Affects Some People Priority: --- Component: bin Assignee: freebsd-bugs@FreeBSD.org Reporter: ki@hh.iij4u.or.jp When I archive VirtualBox's VM directory on ZFS with compression, tar seems to create incorrect archive. I create plain Linux VM and archive on ZFS, but archive size is very small and incorrect. % ls -l Linux/ total 43 -rw------- 1 kit wheel 6883 Jul 12 21:11 Linux.vbox -rw------- 1 kit wheel 6602 Jul 12 21:11 Linux.vbox-prev -rw------- 1 kit wheel 8592031744 Jul 12 21:11 Linux.vdi % tar -cf Linux.tar Linux/ a Linux a Linux/Linux.vdi a Linux/Linux.vbox a Linux/Linux.vbox-prev % ls -l Linux.tar -rw-r--r-- 1 kit wheel 280576 Jul 12 21:28 Linux.tar % tar tvf Linux.tar drwxr-xr-x 0 kit wheel 0 Jul 12 21:11 Linux/ -rw------- 0 kit wheel 8592031744 Jul 12 21:11 Linux/Linux.vdi I found GNU tar works fine, and bsdtar works correctly on UFS or ZFS without compression. I suppose that bsdtar uses compressed size to process, but I cannot find what function has problem. -- You are receiving this mail because: You are the assignee for the bug.
