But I'll leave it for the moment; ext2 will suffice for my simple requirements (I only want to share a few files between FreeBSD and Linux without the overhead of putting them onto the external USB drive which I use for backups). I have of course mounted them rw, now that it's working.

Mount Logical (ext2fs) Partitions?
9.1 on x86_64. No doubt this question has been asked before, but how do I mount logical partitions (e2fs) under FreeBSD? I have checked the handbook, and DuckDuckGo'ed, but without finding anything useful. The third slice on my first disk is a physical one, and will mount happily under FreeBSD. From /etc/fstab: /dev/ada0s3 /Mail ext2fs rw00 But I have a couple of logical partitions (also ext2fs) in the fourth slice, which I have been trying, unsuccessfully, to mount. For information, here is the BSD view of the disk: $ sudo fdisk *** Working on device /dev/ada0 *** parameters extracted from in-core disklabel are: cylinders=310101 heads=16 sectors/track=63 (1008 blks/cyl) Figures below won't work with BIOS for partitions not in cyl 1 parameters to be used for BIOS calculations are: cylinders=310101 heads=16 sectors/track=63 (1008 blks/cyl) Media sector size is 512 Warning: BIOS sector numbering starts with sector 1 Information from DOS bootblock is: The data for partition 1 is: sysid 131 (0x83),(Linux native) start 2048, size 24576000 (12000 Meg), flag 0 beg: cyl 0/ head 32/ sector 33; end: cyl 1023/ head 254/ sector 63 The data for partition 2 is: sysid 165 (0xa5),(FreeBSD/NetBSD/386BSD) start 24578064, size 44040150 (21503 Meg), flag 80 (active) beg: cyl 1023/ head 255/ sector 63; end: cyl 1023/ head 255/ sector 63 The data for partition 3 is: sysid 131 (0x83),(Linux native) start 68618240, size 958464 (468 Meg), flag 0 beg: cyl 1023/ head 254/ sector 63; end: cyl 1023/ head 254/ sector 63 The data for partition 4 is: sysid 5 (0x05),(Extended DOS) start 69577576, size 243002520 (118653 Meg), flag 0 beg: cyl 1023/ head 254/ sector 63; end: cyl 1023/ head 254/ sector 63 $ Now here's how Linux sees it: $ sudo fdisk -l /dev/sda Disk /dev/sda: 160.0 GB, 160041885696 bytes, 312581808 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x38d5b517 Device Boot Start End Blocks Id System /dev/sda120482457804712288000 83 Linux /dev/sda2 *245780646861821322020075 a5 FreeBSD /dev/sda36861824069576703 479232 83 Linux /dev/sda469577576 312580095 1215012605 Extended /dev/sda594158848 112590847 9216000 83 Linux /dev/sda6 112592896 118736895 3072000 82 Linux swap / Solaris /dev/sda7 118738944 1596989432048 83 Linux /dev/sda8 159700992 2416209914096 83 Linux /dev/sda9 241623040 27029913514338048 83 Linux /dev/sda10 270301184 31258009521139456 83 Linux /dev/sda11 695808009415679912288000 83 Linux Partition table entries are not in disk order $ Can anyone provide a pointer please? ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org
