2014-01-20libblkid: detect alone PMBRKarel Zak3-2/+44
wipefs(8) has to also erase PMBR, not GPR header only, otherwise the device could be still interpreted as a device with a partition table. Addresses: https://bugzilla.redhat.com/show_bug.cgi?id=1054186 Signed-off-by: Karel Zak <kzak@redhat.com>
2014-01-16libblkid: no more probe for btrfs backup superblockKarel Zak4-19/+2
* Linux kernel cares about the first superblock only * backup superblock are FS specific stuff and there is no reason to care about it in generic tools * the problem with broken btrfs utils has been already fixed (it was possible to use the utils on filesystem with erased primary superblok without any warning message).

2013-12-12libblkid: Identify extN file system properlyLukas Czerner1-180/+3
Currently when trying to identify extN file system we're playing games with searching for kernel modules and parsing /proc/filesystem. All of this just because ext4 module can be used to mount ext3 and ext2 file systems on recent kernel and also because of ext4dev. However all of this is not necessary. Ext4 module which does support mounting ext2 and ext3 file system is able to recognize and mount ext2 and ext3 type so there is no need to disguise it and ext4dev should only be ever used for testing and not as fallback when other modules are missing (use -t instead). This also introduces a bug when in situation that we only have ext4 modules with ext2/ext3 support which is not loaded and we try to mount ext2 file system we will mount it incorrectly as ext4. This will not happen if the ext4 module is already loaded. With this patch we remove all the unnecessary checks and return the real type of the file system which is on the device. This fixes the issue. However on the kernel which was not compiled with EXT4_USE_FOR_EXT23 support one would have to provide file system type (-t) to be able to mount the file system with ext4 driver.

2013-09-11libblkid: don't use UUID= for xfs external logKarel Zak1-1/+0
The log UUID is usually the same as filesystem UUID, it is bad idea to have two devices with the same UUID in the system. It seems batter to use only LOGUUID= for xfs external log. # mkfs.xfs -l logdev=/dev/sdb1 /dev/sdb2 # blkid -p -o udev /dev/sdb1 | grep FS ID_FS_LOGUUID=4063d453-5c01-46ce-b92f-9523d64aecc7 ID_FS_TYPE=xfs_external_log ID_FS_USAGE=other # blkid -p -o udev /dev/sdb2 | grep FS ID_FS_UUID=4063d453-5c01-46ce-b92f-9523d64aecc7 ID_FS_TYPE=xfs ID_FS_USAGE=filesystem The filesystem (sdb2) uses UUID= and log (sdb1) uses LOGUUID=.

2013-09-11libblkid: don't interpret regual XFS as external xfs logKarel Zak1-0/+3
$ blkid -o udev -p tests/output/blkid/images-fs/xfs.img ID_FS_AMBIVALENT=filesystem:xfs other:xfs_external_log it seems that regular XFS with internal log may be interpreted as log device. This is incorrect. This patch checks for XFS magic string to avoid this collision. Signed-off-by: Karel Zak <kzak@redhat.com>

2013-09-11libblkid: populate jbd LOGUUID in addition to UUIDKarel Zak1-0/+2
The LOGUUID is alias for UUID, this alias is necessary to standardize the tag name (we want to use the same tag LOGUUID= for all external logs on all filesystems). Note that for another filesystems (e.g. xfs) we have to differentiate between the journal and filesystem uuids to avoid collisions, because both devices use the same uuid.

2013-09-11libblkid: rename UUID_LOG to LOGUUIDKarel Zak2-2/+2
* the goal is to make the uuid visible and usable it as mount variable/spec, then LOGUUID= seems better than UUID_LOG= * we already have PARTUUID= * the UUID_RAW and UUID_SUB are not used by mount(8) Signed-off-by: Karel Zak <kzak@redhat.com>
2013-09-11libblkid: Detect external XFS log deviceEric Sandeen3-0/+90
Detects external XFS log devices with a minimum size of 10MB. It's possible to craft a smaller log, but that would be very unlikely; it'd require a small XFS filesystem and an intentionally small log, which would defeat the performance goal of an external log in the first place.

# blkid /dev/sdb1 dev/sdb1: TYPE="ext2" PARTUUID="54e743a7-01" the PARTUUID is generated from MBR Id and partition number. The same method uses Linux kernel for root=PARTUUID= on systems with MBR. Note that the patch also removes 0x prefix from PTUUID. Signed-off-by: Karel Zak <kzak@redhat.com>
