https://bugzilla.kernel.org/show_bug.cgi?id=206429 Bug ID: 206429 Summary: xfs_admin can't print both label and UUID for mounted filesystems Product: File System Version: 2.5 Kernel Version: n/a Hardware: All OS: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: XFS Assignee: filesystem_xfs@xxxxxxxxxxxxxxxxxxxxxx Reporter: vtrefny@xxxxxxxxxx Regression: No Created attachment 287143 --> https://bugzilla.kernel.org/attachment.cgi?id=287143&action=edit patch for xfs_admin Using "xfs_admin -lu" to print both label and UUID of a mounted XFS filesystem stopped working in xfs_admin version 5.4.0. Label is correctly printed, but the UUID is missing: $ sudo xfs_admin -lu /dev/sda label = "aaa" Printing only UUID works as expected: $ sudo xfs_admin -u /dev/sda UUID = a3367b49-6f3f-4f50-9b34-38b1561da085 Command also works as expected for an unmounted filesystem $ sudo xfs_admin -lu /dev/sda label = "aaa" UUID = a3367b49-6f3f-4f50-9b34-38b1561da085 The bug is caused by this change -- https://git.kernel.org/pub/scm/fs/xfs/xfsprogs-dev.git/commit/?id=3f153e051abccce0c120ade5c08a675a50cecee9 -- xfs_io is now used to print label and xfs_admin exists after printing it. I'm attaching a simple naive patch for xfs_admin that fixes this issue. -- You are receiving this mail because: You are watching the assignee of the bug.
