| wasabi__ | Yeah Keybuk, how does readahead find the blocks that are most important? | 23:51 |
| wasabi__ | s/yeah/hey? | 23:51 |
| Keybuk | mincore() | 23:52 |
| wasabi__ | hmm | 23:53 |
| wasabi__ | i'm thinking about making something similar, and running it all the time. | 23:54 |
| wasabi__ | to identify most important blocks on LVM volumes. | 23:54 |
| wasabi__ | and move those to a faster PV (SSD) | 23:54 |
| Keybuk | it's kinda hard to do it that way | 23:54 |
| wasabi__ | It is, but the tools are present. | 23:54 |
| wasabi__ | If I can just find blocks and map to PEs | 23:55 |
| wasabi__ | Would love to add a 10GB SSD to my 500GB disk array, and automatically have the 10GB of data I use most on it | 23:56 |
