* enables GFS/GFS2 probing code (it's disabled now!) * adds support for LABELs -- it seems that locktable name is usable as a LABEL (at least according to libblkid). * removes extra check of sb_header.mh_format -- nothing in kernel and blkid checks this superblock entry. It seems that check GFS_MAGIC and GFS_METATYPE_SB is enough. Signed-off-by: Karel Zak <kzak@redhat.com> |

vol_id - probe filesystem and read label and uuid This program is normally called from a udev rule, to provide udev with the filesystem type of a volume and the label and uuid 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 export key/value pairs --type filesystem type --label filesystem label --label-raw raw label --uuid filesystem uuid --skip-raid don't probe for raid --probe-all find possibly conflicting signatures --help 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 version -------------------------------------------------- linux swap * * * * ext * * * * reiserfs jr/3.5/3.6/4 * * * * fat (12, 16, 32) * * * * ntfs * * * * jfs * * * - xfs * * * - hfs (plus, wrapped) * * * - udf * * - - iso9660 * * - - ufs * - - - cramfs * * - - sysv * * - * luks * - * - hpfs * - - - romfs * * - - squashfs * - - - minix * - - * ocfs (1, 2) * * * * vxfs * - - * nss (netware) * * * gfs, gfs2 * * - - Raid members are detected to prevent the probing for a filesystem ----------------------------------------------------------------- linux raid (md) * * * * LVM 1 * - - - LVM 2 * - - * ddf * - * * highpoint * - - - isw_raid * - - - lsi_raid * - - - nvidia_raid * - - - promise_raid * - - - silicon_raid * - - - via_raid * - - - jmicron * - - - adaptec * - - - 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 --label /dev/sda6 devel $ extras/volume_id/vol_id --type /dev/sda6 ext3 Any comment/questions/concerns to me: Kay Sievers <kay.sievers@vrfy.org>
