Date: Mon, 14 Oct 96 09:12:00 PDT Message-ID: <32626C27@SMTPGATE.PA-CONSULTING.COM> Encoding: 27 TEXT X-Mailer: Microsoft Mail V3.0 Sender: owner-hackers@freebsd.org X-Loop: FreeBSD.org Precedence: bulk Hi In preparing for upgrading from 2.1R to 2.1.5R I backed up my system to my floppy tape using ft and tar. I then run ft on this to just check the tape and get a contents listing. After doing this I found that a few files were corrupted on both of my partitions (/ and /usr). I then tried to reread these (with ft) to / in single user mode and with /usr mounted ro. This caused duplicate inodes to be created and references to block -1 (as stated from fsck). Nothing happened to /usr (so to fix these new problems I'm going to mount a mfs file system and have / ro). This is a little worrying to say the least! I have a UMC based 486 board, with a SGS 486DX2-66, 20meg ram, drives are both IDE hanging from a VESA IO card, also I have a NEC 8bit SCSI card, 3c509 standard VESA graphics. and fax modem. I running stock 2.1R with the patches to ft I sent in via send-pr a while back (should not cause this as they were only to do with adding extra table entries for travan sized tapes).
