我对 AIX 相当陌生，正在尝试创建我的第一个 jfs 文件系统，该系统安装在 /usr1 上。
我首先从可用磁盘创建我的卷组..
#/usr/sbin/mklv -y'vl_usr1' -t'jfs2' -c'2' vg_usr1 6005
van-oppy# lsvg vg_usr1
VOLUME GROUP: vg_usr1 VG IDENTIFIER: 000015010000d60000000140f464119b

LTG size (Dynamic): 256 kilobyte(s) AUTO SYNC: no

下面是逻辑卷的lslv...
# lslv vl_usr1
LOGICAL VOLUME: vl_usr1 VOLUME GROUP: vg_usr1
LV IDENTIFIER: 000015010000d60000000140f464119b.1 PERMISSION: read/write
VG STATE: active/complete LV STATE: closed/syncd
TYPE: jfs2 WRITE VERIFY: off
MAX LPs: 6005 PP SIZE: 128 megabyte(s)
COPIES: 2 SCHED POLICY: parallel
LPs: 6005 PPs: 12010
STALE PPs: 0 BB POLICY: relocatable
INTER-POLICY: minimum RELOCATABLE: yes
INTRA-POLICY: middle UPPER BOUND: 32
MOUNT POINT: N/A LABEL: None
MIRROR WRITE CONSISTENCY: on/ACTIVE
EACH LP COPY ON A SEPARATE PV ?: yes

INFINITE RETRY: no
创建逻辑卷时，我将其设置为 2 个副本，所以现在我的免费 LP 是 6005。
当我接下来尝试创建增强的 JFS2 文件系统时，它失败了..

我很困惑为什么？我的免费 PP 是 6005，所以 6005 x 128 = 768640mb，这是我在创建过程中设置的。我还尝试将数字降低到 768000mb，即 6000 PP，但仍然不行。
任何 AIX 专家都能够阐明为什么这不起作用？试图了解 LVM 的工作原理......
