pv_write is called both to write orphans and to rewrite PV headers of PVs in VGs. It needs to select the correct VG id so that the internal cache state gets updated correctly. It only affected commands that involved further steps after the pv_write and was often masked because the metadata would be re-read off disk and correct itself. "Incorrect metadata area header checksum" warnings appeared. Example: Create vg1 containing dev1, dev2 and dev3. Hide dev1 and dev2 from the system. Fix up vg1 with vgreduce --removemissing. Bring back dev1 and dev2. In a single operation reinstate dev1 and dev2 into vg1 (vgextend). Done as separate operations (automatically fix-up dev1 and dev2 as orphans, then vgextend) it worked, but done all in one go the internal cache got corrupted and warnings about checksum errors appeared. |
