Create jfs2 logical volume on AIX

How to create a jfs2 logical volume on AIX?

First, you need to know:

  • Which volume group you’re going to create the LV. In our case ‘newvg’
[root@aix:/] lsvg -o
rootvg
newvg
  • Volume group PP size. In our case ‘4MB’
[root@aix:/] lsvg newvg|grep "PP SIZE:"
VG STATE:           active                   PP SIZE:        4 megabyte(s)

Now, let’s create the LV named ‘newlv’ with size 8 LPs:

[root@aix:/] mklv -t jfs2 -y newlv newvg 8
newlv

Let’s check logical volume newlv:

[root@aix:/] lsvg -l newvg
newvg:
LV NAME   TYPE   LPs  PPs  PVs    LV STATE     MOUNT POINT
newlv     jfs2    8   8    1    closed/syncd     N/A

[root@aix:/] lslv newlv
LOGICAL VOLUME:     newlv                  VOLUME GROUP:   newvg
LV IDENTIFIER:      000fd1bb0000d4000000015988de0d0f.1 PERMISSION:     read/write
VG STATE:           active/complete        LV STATE:       closed/syncd
TYPE:               jfs2                   WRITE VERIFY:   off
MAX LPs:            512                    PP SIZE:        4 megabyte(s)
COPIES:             1                      SCHED POLICY:   parallel
LPs:                8                      PPs:            8
STALE PPs:          0                      BB POLICY:      relocatable
INTER-POLICY:       minimum                RELOCATABLE:    yes
INTRA-POLICY:       middle                 UPPER BOUND:    1024
MOUNT POINT:        N/A                    LABEL:          None
DEVICE UID:         0                      DEVICE GID:     0
DEVICE PERMISSIONS: 432
MIRROR WRITE CONSISTENCY: on/ACTIVE
EACH LP COPY ON A SEPARATE PV ?: yes
Serialize IO ?:     NO
INFINITE RETRY:     no
DEVICESUBTYPE:      DS_LVZ
COPY 1 MIRROR POOL: None
COPY 2 MIRROR POOL: None
COPY 3 MIRROR POOL: None

 

Now you’re ready to create the file system over that logical volume. See next post.
