Hi, Thanks to Mr. Andrey V. Elsukov's advice, I could RESOLVE the problem (trouble) mentioned originally at * URL: http://lists.freebsd.org/pipermail/freebsd-geom/2012-July/005345.html Date: Mon, 23 Jul 2012 13:46:58 +0900 Message-ID: <20120723134658.153fa6c%mur1080224@inter7.jp> To: freebsd-geom@freebsd.org From: Norihiko Murase <mur1080224@inter7.jp> Subject: (8.3-RELEASE,9.1-BETA) Can't mount the partitions created via 4.11-RELEASE Now, the partitions in the "old" HDD that were created by 4.11-RELEASE can be mount(8)-ed successfully under 8.3-RELEASE and under 9.1-BETA as well as under 7.4-RELEASE. The solution was shown by Mr. Andrey V. Elsukov at * URL: http://lists.freebsd.org/pipermail/freebsd-geom/2012-July/005348.html Date: Mon, 23 Jul 2012 16:10:19 +0400 Message-ID: <500D3F2B.9090509@yandex.ru> From: "Andrey V. Elsukov" <bu7cher@yandex.ru> Subject: Re: (8.3-RELEASE,9.1-BETA) Can't mount the partitions created via 4. 11-RELEASE |>You can try backup first 16 sectors and try to overwrite second sector |>(where bsdlabel is) with zeroes. As this e-mail message says, I executed the following command: # dd if=/dev/zero of=/dev/ad16 count=1 seek=1 under the live system of FreeBSD 7.4-RELEASE, and then rebooted. # Well, the backup of the top 16 sectors were not necessary # eventually. :-) After that, the partitions can be mount(8)-ed successfully via the device node "ad16s[12]*" without any trouble. As he said, the contents in the sector 2 (counting from 1) of this "old" HDD were stale and junk, which prevented the system from mount(8)-ing the partitions. Additionally, after the reboot, the following "ad#c" device nodes: ad16c ad16cs1 ad16cs1{a,b,c,e,f,g} ad16cs2 ad16cs2{c,e} were NOT found in /dev any longer under the live system of FreeBSD 7.4-RELEASE. To Mr. Andrey V. Elsukov: Thank you very much for your advice!! Sincerely, --- Norihiko Murase <mur1080224@inter7.jp>
