扩容TrueNAS的boot-pool大小
因为之前使用一块小的32G固态做启动盘，因为之前的truneNAS也不怎么写启动盘，后来升级到24大版本后就狂写入，很快32G的固态就寿命耗尽了，只好换个块闲置的1T机械盘给他顶替。
切换硬盘做boot-pool到时很简单，菜单里面就搞定了。但是替换后的硬盘布局还是之前的32G固态的，不会自动扩容，然后自己就研究了下怎么扩容，基本办法如下：
- 基本操作命令
# list of set commands zpool set # check autoexpand status zpool get autoexpand,expandsize # enable autoexpand zpool set autoexpand=on <pool name> # expand online zpool online -e <pool name> <disk partition>
admin@truenas[~]$ sudo -i
[sudo] password for admin:
root@truenas[~]# zpool set
missing property=value argument
usage:
set <property=value> <pool>
set <vdev_property=value> <pool> <vdev>
the following properties are supported:
PROPERTY EDIT VALUES
allocated NO <size>
bcloneratio NO <1.00x or higher if cloned>
bclonesaved NO <size>
bcloneused NO <size>
capacity NO <percent>
checkpoint NO <size>
dedup_table_size NO <size>
dedupratio NO <1.00x or higher if deduped>
expandsize NO <size>
fragmentation NO <percent>
free NO <size>
freeing NO <size>
guid NO <guid>
health NO <state>
last_scrubbed_txg NO <txg>
leaked NO <size>
load_guid NO <load_guid>
size NO <size>
altroot YES <path>
ashift YES <ashift, 9-16, or 0=default>
autoexpand YES on | off
autoreplace YES on | off
autotrim YES on | off
bootfs YES <filesystem>
cachefile YES <file> | none
comment YES <comment-string>
compatibility YES <file[,file...]> | off | legacy
dedup_table_quota YES <size>
delegation YES on | off
failmode YES wait | continue | panic
listsnapshots YES on | off
multihost YES on | off
readonly YES on | off
version YES <version>
feature@... YES disabled | enabled | active
The feature@ properties must be appended with a feature name.
See zpool-features(7).
root@truenas[~]# zpool status
pool: boot-pool
state: ONLINE
status: One or more devices has experienced an error resulting in data
corruption. Applications may be affected.
action: Restore the file in question if possible. Otherwise restore the
entire pool from backup.

最后再看下菜单的boot的大小，已经扩容到1T硬盘的大小了，收工。
