| + | The reesi have 11x 4TB HDD, 1x 12TB HDD, and 1x 800GB NVMe. | ||
| + | |||
| + | The 12TB were added to so we can say we're testing on drives larger than 8TB. | ||
| + | |||
| + | The NVMe device is split into two equal partitions: | ||
| + | - Split into 12 LVMs to serve as block.db for each HDD OSD | ||
| + | - Used as an SSD OSD | ||

| + | ===== Replacing Drives ===== | ||
| + | Like the [[hardware:mira]], the drive letters do **not** correspond to drive bays. So ''/dev/sda'' isn't necessarily in Drive Bay 1. Keep this in mind when zapping/setting up OSDs. Also, drive ''/dev/sda'' may not necessarily have its WAL Block on ''/dev/journals/sda''. | ||
| + | |||
| + | While watching the front of a system, send ''dd if=/dev/$DRIVE of=/dev/null'' where ''$DRIVE'' is the drive you're replacing to identify each drive. | ||
