| Description |
|
Now only plain directory migration is tested in racer.sh, the test script should be improved to support striped directory migration, and it should be stable, because after directory restripe support, it will become common to migrate striped directory on a system with other loads. |

Is it possible to separate lfs migrate doing directory restripe, where only the name entries are moved from the migration of the inodes? I think that moving only the entries is much easier to get working correctly, since it doesn't involve copying the inodes, xattrs, changing the FID,updating the hard links, updating the parent back pointer on the OST objects, etc. For automatic directory split we would only do the name move, and not the inode move, so having some way to request this from lfs migrate would be good so it can be tested separately. |

Yes, it can be added, but we should add support for lots of agent for remote files. |
