vol_id - partition, filesystem, disklabel reader This program is normally called from a udev rule, to provide udev with the name, uuid or the filesystem type of a partition to name a device node. vol_id opens the blockdevice node specified at the commandline. The following commandline switches are supported to specify what vol_id should print: --export prints all values -h prints help text -l prints the label of the partition -u prints the uuid of the partition vol_id will only return successful if the string asked for, is not empty. All trailing whitespace will be removed, spaces replaced by underscore and slashes ignored. fstype probe label uuid fsversion ---------------------------------------------------- ext * * * * reiserfs jr/3.5/3.6/4 * * * * fat (12, 16, 32) * * * * ntfs * * * * jfs * * * - xfs * * * - hfs (plus, wrapped) * * * - udf * * - - iso9660 * * n/a - ufs * - - - linux swap * * * * LVM 1 * - - - LVM 2 * - - * linux raid * - * * cramfs * * - - sysv * * - * luks * - * - hpfs * - - - romfs * squashfs * minix * highpoint * isw_raid * lsi_raid * nvidia_raid * promise_raid * silicon_raid * via_raid * If no label is found vol_id exits with nonzero and the rule will be ignored. To give it a try, you may call it on the commandline: $ extras/volume_id/vol_id --export /dev/sda6 ID_FS_USAGE=filesystem ID_FS_TYPE=ext3 ID_FS_VERSION=1.0 ID_FS_UUID=3e999973-00c9-4917-9442-b7633bd95b9e ID_FS_LABEL=devel ID_FS_LABEL_SAFE=devel $ extras/volume_id/vol_id -l /dev/sda6 devel $ extras/volume_id/vol_id -t /dev/sda6 ext3 Any comment/questions/concerns to me: Kay Sievers <kay.sievers@vrfy.org>
