I tried it already and doesn't help much. The only trick I found (by
chance and I don't know the real reason) to reduce GET_INFO_FS is to
stop robinhood, umount and mount lustre again and restart robinhood. I
did it and this is the result:
Stage | Wait | Curr | Done | Total | ms/op |
0: GET_FID | 0 | 0 | 0 | 0 | 0.00 |
1: GET_INFO_DB |99997 | 3 | 0 | 1370749 | 0.25 |
2: GET_INFO_FS | 0 | 0 | 0 | 501077 | 0.18 |
3: REPORTING | 0 | 0 | 0 | 2520 | 0.00 |
4: PRE_APPLY | 0 | 0 | 0 | 374336 | 0.00 |
5: DB_APPLY | 0 | 0 | 0 | 374336 | 0.18 | 0.01%
batched (avg batch size: 2.0)
6: CHGLOG_CLR | 0 | 0 | 0 | 1022160 | 0.03 |
7: RM_OLD_ENTRIES | 0 | 0 | 0 | 0 | 0.00 |

Unfortunately this is only temporary (~ 1 day).
Thank you very much for all.
