From ac383de20d468a75e7023caf06dcf6606cd85220 Mon Sep 17 00:00:00 2001 From: Dave Chinner Date: Wed, 19 Aug 2015 10:31:41 +1000 Subject: [PATCH] xfs: growfs not aware of sb_meta_uuid Adding this simple change to xfstests:common/rc::_scratch_mkfs_xfs: + if [ $mkfs_status -eq 0 ]; then + xfs_admin -U generate $SCRATCH_DEV > /dev/null + fi triggers all sorts of errors in xfstests. xfs/104 is an example, where growfs fails with a UUID mismatch corruption detected by xfs_agf_write_verify() when trying to write the first new AG headers. Fix this problem by making sure we copy the sb_meta_uuid into new metadata written by growfs.
