+/*
+
+ This is a 2nd implemetation of a shadow copy module for exposing
+ snapshots to windows clients as shadow copies. This version has the
+ following features:
+
+ 1) you don't need to populate your shares with symlinks to the
+ snapshots. This can be very important when you have thousands of
+ shares, or use [homes]
+
+ 2) the inode number of the files is altered so it is different
+ from the original. This allows the 'restore' button to work
+ without a sharing violation
+
+ Module options:
+
+ shadow:snapdir = <directory where snapshots are kept>
+
+ This is the directory containing the @GMT-* snapshot directories. If it is an absolute
+ path it is used as-is. If it is a relative path, then it is taken relative to the mount
+ point of the filesystem that the root of this share is on
+
+ shadow:basedir = <base directory that snapshots are from>
+
+ This is an optional parameter that specifies the directory that
+ the snapshots are relative to. It defaults to the filesystem
+ mount point
+
+ shadow:fixinodes = yes/no
+
+ If you enable shadow:fixinodes then this module will modify the
+ apparent inode number of files in the snapshot directories using
+ a hash of the files path. This is needed for snapshot systems
+ where the snapshots have the same device:inode number as the
+ original files (such as happens with GPFS snapshots). If you
+ don't set this option then the 'restore' button in the shadow
+ copy UI will fail with a sharing violation.
+
+ Note that the directory names in the snapshot directory must take the form
+ @GMT-YYYY.MM.DD-HH.MM.SS
+
+ The following command would generate a correctly formatted directory name:
+ date -u +@GMT-%Y.%m.%d-%H.%M.%S

+ This VFS module accepts following options:
+ tsmsm: hsm script = <path to hsm script> (/bin/true by default, i.e. does nothing)
+ hsm script should point to a shell script which accepts two arguments:
+ <operation> <filepath>
+ where <operation> is currently 'offline' to set offline status of the <filepath>
+
+ tsmsm: online ratio = ratio to check reported size against actual file size (0.5 by default)
+
+ The TSMSM VFS module tries to avoid calling expensive DMAPI calls with some heuristics
+ based on the fact that number of blocks reported of a file multiplied by 512 will be
+ bigger than 'online ratio' of actual size for online (non-migrated) files.
+
+ If checks fail, we call DMAPI and ask for specific IBM attribute which present for
+ offline (migrated) files. If this attribute presents, we consider file offline.
