| DHE | yeah ZFS only updates that stuff on a full disk flush. with a filesystem supporting compression and variable chunk sizes you can't know how much space something takes up until you actually write it | 00:00 |
|---|---|---|
| renich | It was a bad idea to set it up as it is, but we have had to live with it for years now. | 00:01 |
| DHE | I actually dismantled a ZFS pool of 132 disks (plus a few spares) and put it into a swift cluster | 00:02 |
| renich | as in migrate stuff to the swift cluster? | 00:02 |
| renich | pretty cool. | 00:02 |
| DHE | yeah | 00:03 |
| DHE | but there was a lot of additional hardware involved, including borrowing machines intended for a whole separate project | 00:03 |
| renich | The boss didn't want pure swift because of the replicas. He decided to entrust data integrity to raidz2. | 00:03 |
| DHE | and in fairness ZFS is quite good at that. but I have IOPS expectations that are met by spindles and raidz does not provide that | 00:04 |
| renich | yeah, believe me, I know... | 00:04 |
