>Number: 466 >Category: kern >Synopsis: Unexpected disk errors during installation/newfs >Confidential: no >Severity: critical >Priority: high >Responsible: freebsd-bugs (FreeBSD bugs mailing list) >State: open >Class: sw-bug >Submitter-Id: current-users >Arrival-Date: Wed May 31 21:40:01 1995 >Originator: Gil Kloepfer Jr. >Organization: SSDL >Release: FreeBSD 2.0.5-ALPHA i386 >Environment: 386DX/40 ISA bus, no mathco, 8MB memory Adaptec 2322B ESDI controller 2 Maxtor XT-4380E ESDI drives **IMPORTANT** Disks are configured using sector sparing through controller low-level format. This reserves 1 sec/trk for bad blocks so that the disk appears "flawless" at low-level format time. This means that the advertised disk geometry of 1222cyl/15h/36sec is hardware changed to 1222cyl/15h/35sec >Description: After completing configuration questions, started install, and the following message appeared on the screen: Unable to make root filesystem! Command returned status 36 The debug window had the following messages (messages not pertaining to problem deleted): Warning: calculated sectors per cylinder (4096) disagrees with disk label (525) /dev/rwd0a: 40960 sectors in 10 cylinders of 1 tracks, 4096 sectors 20.0MB in 1 cyl groups (16 c/g, 32.00MB/g, 7680 i/g) wd0a: hard error writing fsbn 68 or 64-79 (wd0 bn 68; cn 0 tn 1 sn 33) wd0: status 51<seekdone,err> error 10<no_id> super-block backups (for fsck -b #) at:write error: 64 wtfs: input/output error Another note that may help ... I noticed that the kernel message describing the disk when the kernel was booting identified the disk's physical geometry, and not the geometry as handled by the controller (using sector sparing). The disk layout that I configured in the earlier part of the installation was a 60MB DOS partition (existing), 20MB root, 32MB swap, 80MB /usr, 10MB /var, remaining /source. >How-To-Repeat: Perform installation again. Note...I am more than willing to test different kernels and/or procedures in an effort to help track the problem. The machine I am using is currently specifically for FreeBSD staging before moving the new OS to my production machine. >Fix: Unknown. >Audit-Trail: >Unformatted:
