Seems that one function call is missing in the back trace between auto_sense and UDiv, because UDiv does not setup a complete stack frame. Looking at the source ... http://src.opensolaris.org/source/xref/onnv/onnv-gate/usr/src/cmd/format/auto_sense.c#819 ... you can get some extra debug output from format when you specify the "-M" option. E.g. with an usb flash memory stick and format -eM I get # format -eM Searching for disks... c11t0d0: attempting auto configuration Inquiry: 00 80 02 02 1f 00 00 00 53 61 6e 44 69 73 6b 20 ........SanDisk 55 33 20 43 6f 6e 74 6f 75 72 20 20 20 20 20 20 U3 Contour 34 2e 30 4.0 Product id: U3 Contour Capacity: 00 7a 46 90 00 00 02 00 blocks: 8013456 (0x7a4690) blksize: 512 disk name: `r ` Request sense for command mode sense failed Sense data: f0 00 05 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 Mode sense page 0x3 failed Request sense for command mode sense failed Sense data: f0 00 05 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 Mode sense page 0x4 failed Geometry: pcyl: 1956 ncyl: 1954 heads: 128 nsects: 32 acyl: 2 bcyl: 0 rpm: 0 nblocks: 8013457 The current rpm value 0 is invalid, adjusting it to 3600 Geometry after adjusting for capacity: pcyl: 1956 ncyl: 1954 heads: 128 nsects: 32 acyl: 2 rpm: 3600 Partition 0: 128.00MB 64 cylinders Partition 1: 128.00MB 64 cylinders Partition 2: 3.82GB 1956 cylinders Partition 6: 3.56GB 1825 cylinders Partition 8: 2.00MB 1 cylinders Inquiry: 00 00 03 02 1f 00 00 02 41 54 41 20 20 20 20 20 ........ATA 48 69 74 61 63 68 69 20 48 54 53 37 32 33 32 33 Hitachi HTS72323 43 33 30 C30 done c11t0d0: configured with capacity of 3.82GB -- This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
