From 683297eefebe83f848daad9927871242ab28ef91 Mon Sep 17 00:00:00 2001 From: Lee Chee Yang Date: Mon, 13 Apr 2020 19:00:54 +0800 Subject: wic: use Filesystem UUID when expand swap partition part.get("uuid") return the Partition UUID from the partition table instead of Filesystem UUID. This lead to swap partition UUID not match/change when wic write expand swap partition. change it to read the filesystem UUID using blkid. The output from blkid should looks like this: wic-partvzhiwq3s: LABEL="swap1" UUID="04e55c19-3f3f-4491-9e32-44eea8daa827" VERSION="1" TYPE="swap" USAGE="other" [YOCTO #13313] Signed-off-by: Lee Chee Yang Signed-off-by: Richard Purdie --- scripts/lib/wic/engine.py | 5 +++-- 1 file changed, 3 insertions(+), 2 deletions(-) diff --git a/scripts/lib/wic/engine.py b/scripts/lib/wic/engine.py index 9ff4394757..018815b966 100644 --- a/scripts/lib/wic/engine.py +++ b/scripts/lib/wic/engine.py @@ -280,7 +280,7 @@ class Disk: def __getattr__(self, name): """Get path to the executable in a lazy way.""" if name in ("mdir", "mcopy", "mdel", "mdeltree", "sfdisk", "e2fsck", - "resize2fs", "mkswap", "mkdosfs", "debugfs"): + "resize2fs", "mkswap", "mkdosfs", "debugfs","blkid"): aname = "_%s" % name if aname not in self.__dict__: setattr(self, aname, find_executable(name, self.paths)) @@ -543,7 +543,8 @@ class Disk: logger.info("creating swap partition {}".format(pnum)) label = part.get("name") label_str = "-L {}".format(label) if label else '' - uuid = part.get("uuid") + out = exec_cmd("{} --probe {}".format(self.blkid, self._get_part_image(pnum))) + uuid = out[out.index("UUID=\"")+6:out.index("UUID=\"")+42] uuid_str = "-U {}".format(uuid) if uuid else '' with open(partfname, 'w') as sparse: os.ftruncate(sparse.fileno(), part['size'] * self._lsector_size) -- cgit 1.2.3-korg
