David Teigland e035e32350 scan: retry reading metadata on error ... If label_scan encounters bad vg metadata, invalidate bcache data for the device and reread the mda_header and metadata text back to back. With concurrent commands modifying large metadata, it's possible that the entire metadata area can be rewritten in the time between a command reading the mda_header and reading the metadata text that the header points to. Since the label_scan is just assembling an initial overview of devices, it doesn't use locking to serialize with other commands that may be modifying the vg metadata at the same time.		2021-07-06 10:10:23 -05:00
