1 | >= 12.1.2 |
2 | --------- | |
3 | * When running 'df' on a CephFS filesystem comprising exactly one data pool, | |
4 | the result now reflects the file storage space used and available in that | |
5 | data pool (fuse client only). | |
6 | * Added new commands "pg force-recovery" and "pg-force-backfill". Use them | |
7 | to boost recovery or backfill priority of specified pgs, so they're | |
8 | recovered/backfilled before any other. Note that these commands don't | |
9 | interrupt ongoing recovery/backfill, but merely queue specified pgs | |
10 | before others so they're recovered/backfilled as soon as possible. | |
11 | New commands "pg cancel-force-recovery" and "pg cancel-force-backfill" | |
12 | restore default recovery/backfill priority of previously forced pgs. | |

18 | * Clusters will need to upgrade to 12.2.1 before upgrading to any | |
19 | Mimic 13.y.z version (either a development release or an eventual | |
20 | stable Mimic release). | |

24 | * Limiting MDS cache via a memory limit is now supported using the new | |
25 | mds_cache_memory_limit config option (1GB by default). A cache reservation | |
26 | can also be specified using mds_cache_reservation as a percentage of the | |
27 | limit (5% by default). Limits by inode count are still supported using | |
28 | mds_cache_size. Setting mds_cache_size to 0 (the default) disables the | |
29 | inode limit. |
