Description
during migration we put old objects onto /PENDING and leave it there till the next reboot (PENDING cleanup). this approach has a number of problems:
1) space (inodes and directories) aren't released
so if one wanted to rebalance/free space on MDT will have to reboot it
2) PENDING/ may become huge slowing down regular unlinks
this is especially bad as it never shrink
