I have a prod system with several tera of SAN disk attached. The
filesystem was acting up and the drive has critical issues now on
about 30% of the data, and we need to run a checkdisk to repair the
issue. The downside is that it'll take over 3 days of downtime to run
checkdisk due to the size of data, and the fact that checkdisk
requires that we unmount the drives so users are all ofline for that
time.

Since there's no 3 day weekends coming up soon does anyone have an
idea to fix the drives without unmounting them?
