Subject: [PATCH 21/21] Avoid dev/inode check on btrfs with --sanity-level=3
|
|
|
|
With --sanity-level=3 or higher the aspacemgr sanity checks the
|
|
device/inode numbers from /proc/self/maps to the file stat
|
|
results. These don't match on btrfs. So detect when a file is on a
|
|
btrfs volume and ignore the check in that case.
|
