From: Filipe Manana <fdmanana@xxxxxxxx> After doing log replay, btrfs/192 is overwriting the $seqres.full file because it uses the plain ">" redirect operator, instead of an append ">>" redirect operator. As a consequence it is overriding the file and eliminating any previous output that may be useful to debug a test failure (such as the fsstress seed or mkfs results). So use >> instead of >.
