Why are files not being moved by the Mover?
These are some common reasons the Mover is not working as expected:
If using the mover tuning plugin first thing to do is to check its settings or remove it and try without it just to rule it out.
use cache pool option for the share(s) is not correctly set, for 6.11.5 or older see here for more details but basically cache=yes moves data from pool to array, cache=prefer moves data from array to pool, cache=only and cache=no options are not touched by the Mover, for v6.12.0 or newer chech that the shares have the pool as primary storage, array as secondary storage and mover action set to move from pool to array
files are open, they already exist or there's not enough space in the destination, enable Mover logging (Settings -> Scheduler -> Mover Settings) and it will show in the syslog what the error is.
if it's a not enough space error note that split level overrides allocation method, also minimum free space for the share(s) must be correctly set, usual recommendation is to set it to twice the max file size you expect to copy/move to that share.
If none of these help enable Mover logging, run the Mover, download the diagnostics and please attach them to a new or your existing thread in the general support forum, also mention the share name(s) that you want/expect data to be moved.
