Subject: [PATCH v2 0/2] btrfs-progs: make "btrfstune -S1" to reject fs with dirty log
Date: Tue, 19 Apr 2022 19:36:20 +0800 [thread overview]
Message-ID: <cover.1650368004.git.wqu@suse.com> (raw)
[CHANGELOG]
v2:
- Add a test case for it
A seed device with dirty log can be rejected by kernel, as kernel will
try to replay log even on RO mount.
But log replay on RO device is strongly prohibited, thus such seed
device will be rejected without a way to sprout.
Fix the problem by letting "btrfstune -S1" to check if the fs has dirty
log first.
Also add a test case for it, using a btrfs-image dump.
Qu Wenruo (2):
btrfs-progs: do not allow setting seed flag on fs with dirty log
btrfs-progs: make sure "btrfstune -S1" will reject fs with dirty log
