Hi, I've done a quick test on changing the UUID of a btrfs. It worked, but btrfstune -u didn't print the same current uuid that btrfs fi sh does. It also upper cases the UUID where as btrfs fi sh and blkid don't.
Thanks, Mike # btrfs filesystem show /dev/sdb1 | fgrep uuid Label: none uuid: b2813976-4d8b-4976-9d59-cbfbd588399c # ~fedora/programming/c/btrfs-progs-unstable/btrfstune -f -u /dev/sdb1 Current fsid: FFFFFFFF-0000-0000-00B0-8F12937F0000 New fsid: D294F3F3-F2B7-4407-B83A-DE5A4F8CBAB1 Set superblock flag CHANGING_FSID Change fsid in extents Change fsid on devices Clear superblock flag CHANGING_FSID Fsid change finished # btrfs filesystem show /dev/sdb1 | fgrep uuid Label: none uuid: d294f3f3-f2b7-4407-b83a-de5a4f8cbab1 # blkid | fgrep sdb1 /dev/sdb1: UUID="d294f3f3-f2b7-4407-b83a-de5a4f8cbab1" UUID_SUB="70065403-5ec1-462c-93a4-26cff8b6aea2" TYPE="btrfs" PARTUUID="b309c48c-486f-4882-896c-34d4d0aeb529" -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
