How to increase LP count in AIX filesystem ?
Today we will see how to increase LP count of an AIX filesystem.
LP count is a limit set in a particular LV where we can’t increase the size of LV more than that limit even if the space is available in VG.
1. First check the filesystem for which we wish to increase the LP count.
ngeaix560 --> df -gt /oragrid Filesystem GB blocks Used Free %Used Mounted on /dev/prodglv 129.81 52.99 76.82 41% /oragrid
2. List the logical volume details to get the count of LPs.
ngeaix560 --> lslv prodglv LOGICAL VOLUME: prodglv VOLUME GROUP: productsvg LV IDENTIFIER: 00cfc34700004c0000000164cbd205f1.4 PERMISSION: read/write VG STATE: active/complete LV STATE: opened/syncd TYPE: jfs2 WRITE VERIFY: off MAX LPs: 2277 PP SIZE: 64 megabyte(s) COPIES: 1 SCHED POLICY: parallel LPs: 2077 PPs: 2077 STALE PPs: 0 BB POLICY: relocatable INTER-POLICY: minimum RELOCATABLE: yes INTRA-POLICY: middle UPPER BOUND: 1024 MOUNT POINT: /oragrid LABEL: /oragrid 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 PREFERRED READ: 0 DEVICESUBTYPE: DS_LVZ COPY 1 MIRROR POOL: None COPY 2 MIRROR POOL: None COPY 3 MIRROR POOL: None
3. Increase the LP count now.
ngeaix560 --> chlv -x 3000 prodglv ## Check if its increased now. ngeaix560 --> lslv prodglv LOGICAL VOLUME: prodglv VOLUME GROUP: productsvg LV IDENTIFIER: 00cfc34700004c0000000164cbd205f1.4 PERMISSION: read/write VG STATE: active/complete LV STATE: opened/syncd TYPE: jfs2 WRITE VERIFY: off MAX LPs: 3000 PP SIZE: 64 megabyte(s) COPIES: 1 SCHED POLICY: parallel LPs: 3000 PPs: 2077 STALE PPs: 0 BB POLICY: relocatable INTER-POLICY: minimum RELOCATABLE: yes INTRA-POLICY: middle UPPER BOUND: 1024 MOUNT POINT: /oragrid LABEL: /oragrid 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 PREFERRED READ: 0 DEVICESUBTYPE: DS_LVZ COPY 1 MIRROR POOL: None COPY 2 MIRROR POOL: None COPY 3 MIRROR POOL: None ngeaix560 -->
