* Pool configuration is stored as a packed nvlist on the filesystem. By |
48 |
* default, all pools are stored in /etc/zfs/zpool.cache and loaded on boot |
|
49 |
* (when the ZFS module is loaded). Pools can also have the 'cachefile' |
|
50 |
* property set that allows them to be stored in an alternate location until |
|
51 |
* the control of external software. |
|
789 | 52 |
* |
5363 | 53 |
* For each cache file, we have a single nvlist which holds all the |
54 |
* configuration information. When the module loads, we read this information |
|
55 |
* from /etc/zfs/zpool.cache and populate the SPA namespace. This namespace is |
|
56 |
* maintained independently in spa.c. Whenever the namespace is modified, or |
|
57 |
* the configuration of a pool is changed, we call spa_config_sync(), which |
|
58 |
* walks through all the active pools and writes the configuration to disk. |
