Hi,
Can someone point me to instructions on how to understand the scope of
damage to this filesystem based on the output from xfs_repair below?
What is it repairing, and what data is lost? I'm not sure how to interpret
these messages or where to go to find out.
I'm using xfs_repair v2.8.18 on Ubuntu Linux.
Thks,
Chris
