And thus the output as seen in the latest btrfs fi show and btrfs fi show -m for the mounted disks will have the consistent disks path. (it was inconsistent (across disks) because btrfs dev scan provided a different path from the mount command eg. below) devid 1 size 1.98GiB used 435.00MiB path /dev/mapper/mpatha devid 2 size 2.00GiB used 415.00MiB path /dev/dm-1 Signed-off-by: Anand Jain --- cmds-device.c | 2 +- 1 files changed, 1 insertions(+), 1 deletions(-) diff --git a/cmds-device.c b/cmds-device.c index 7cfc347..1315918 100644 --- a/cmds-device.c +++ b/cmds-device.c @@ -189,7 +189,7 @@ static const char * const cmd_scan_dev_usage[] = { static int cmd_scan_dev(int argc, char **argv) { int i, fd, e; - int where = BTRFS_SCAN_PROC; + int where = BTRFS_SCAN_LBLKID; int devstart = 1; if( argc > 1 && !strcmp(argv[1],"--all-devices")){ -- 1.7.1
