Note that UFS in FreeBSD does support labels. I believe it is the '-L' option to newfs. ZFS does not in this sense, and ZFS touches the end of the partition. That's a long list of conditions. So, really, glabel should typically be avoided. thanks for the explaination. I am not able to use the labels outside gpart but if they work for me - as it currently looks like - I will stick with them. I will later report in more detail when I have finished my scripts.

See my reply in -fs: http://lists.freebsd.org/pipermail/freebsd-fs/2013-January/016113.html Sorry, forgot to mention that one possible use for glabel is to label a swap partition on an MBR drive. # glabel label myswap /dev/ada0s1b And then in /etc/fstab: /dev/label/myswap noneswapsw 0 0 One block is used for metadata at the end of ada0s1b, but it's safe from overwriting because /dev/label/myswap does not include that block. ___ 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
gpart, glabel and newfs -- what am I doing wrong
Hi, in general, I try to create the partitions with gpart, add a label with glabel and put a filesystem. I think that I am doing something very simple the wrong way but I cannot see the error. I try to do it in the following way: # gpart destroy -F da0 # gpart create -s GPT da0 # gpart add -t freebsd-boot -s 64k da0 # gpart bootcode -b /boot/pmbr -p /boot/gptboot -i 1 da0 # gpart add -t freebsd-ufs -s 512m -a 4k -l Toshiba16GB2boot da0 # gpart add -t freebsd-ufs -s 10m -a 4k -l Toshiba16GB2root da0 # gpart add -t freebsd-swap -s 10m -a 4k -l Toshiba16GB2swap da0 # gpart add -t freebsd-ufs -s 10m -a 4k -l Toshiba16GB2var da0 # gpart add -t freebsd-ufs -s 10m -a 4k -l Toshiba16GB2tmp da0 # gpart add -t freebsd-ufs -a 4k -l Toshiba16GB2usr da0 Label the partitions: # glabel label Toshiba16GB2boot /dev/da0p2 # glabel label Toshiba16GB2root /dev/da0p3 # glabel label Toshiba16GB2swap /dev/da0p4 # glabel label Toshiba16GB2var /dev/da0p5 # glabel label Toshiba16GB2tmp /dev/da0p6 # glabel label Toshiba16GB2usr /dev/da0p7 And put a file system onto the partitions. # newfs /dev/label/Toshiba16GB2boo # newfs /dev/label/Toshiba16GB2roo # newfs /dev/label/Toshiba16GB2var # newfs /dev/label/Toshiba16GB2tmp # newfs /dev/label/Toshiba16GB2usr But newfs on the first partition results in this: Filesystem size 15 minimum size of 48 When I ran the newfs directly on the device, I get this: [X220]/home/erich (root) newfs /dev/da0p2 /dev/da0p2: 512.0MB (1048576 sectors) block size 32768, fragment size 4096 using 4 cylinder groups of 128.03MB, 4097 blks, 16512 inodes. super-block backups (for fsck -b #) at: 192, 262400, 524608, 786816 Of course, this is what I expect. I believe that it is something simple but I am not able to see my mistake.

Re: gpart, glabel and newfs -- what am I doing wrong
FWIW I could not partition using the FreeBSD 9.0 amd64 install DVD. I partitioned with the PcBSDÂ 8.2 DVD and then tried to install from 9.0, but it anyway caused partitioning issues. After that I partitioned using FreeBSD 8.3, installed 8.3 and then updated to 9.1.

You already created GPT labels with 'gpt -l' above. And those labels don't need extra metadata at the end of the partition. And put a file system onto the partitions. # newfs /dev/label/Toshiba16GB2boo # newfs /dev/label/Toshiba16GB2roo # newfs /dev/label/Toshiba16GB2var # newfs /dev/label/Toshiba16GB2tmp # newfs /dev/label/Toshiba16GB2usr Those look cut off. And there's surely a limit to the length of label names, but I'm not sure what it is. Anyway, use # newfs /dev/gpt/Toshiba16GB2boot And consider using -U with newfs. ___ 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
