HANA磁盘在线扩容-字符方式

一.扩PV
PO-HANA-PRD2:~ # pvresize -t /dev/vdc
  TEST MODE: Metadata will NOT be updated and volumes will not be (de)activated.
  Physical volume "/dev/vdc" changed
  1 physical volume(s) resized or updated / 0 physical volume(s) not resized
PO-HANA-PRD2:~ # pvresize  /dev/vdc
  Physical volume "/dev/vdc" changed
  1 physical volume(s) resized or updated / 0 physical volume(s) not resized
PO-HANA-PRD2:~ # pvdisplay

二、查询vg hanavg的可用空间
PO-HANA-PRD2:~ # vgdisplay hanavg
  --- Volume group ---
  VG Name               hanavg

  MAX LV                0
  Cur LV                1
  Open LV               1
  Max PV                0
  Cur PV                2
  Act PV                2
  VG Size               1.37 TiB
  PE Size               4.00 MiB
  Total PE              358398

  VG UUID               qIAruX-yp8n-qbCO-sqvU-DIbX-2w5E-7R3j4c
三、扩lv
PO-HANA-PRD2:~ # lvdisplay
  --- Logical volume ---
  LV Path                /dev/hanavg/hanalv
  LV Name                hanalv
  VG Name                hanavg
  LV UUID                OmfG88-2Ty3-Ezr5-ft8k-ZxCk-exaQ-urEwNB
  LV Write Access        read/write
  LV Creation host, time PO-HANA-PRD2, 2020-11-09 11:22:46 +0800
  LV Status              available
  # open                 1

  Block device           254:0
   
PO-HANA-PRD2:~ # lvextend -l 100%VG /dev/hanavg/hanalv
  Size of logical volume hanavg/hanalv changed from 1.10 TiB (288358 extents) to 1.37 TiB (358398 extents).
  Logical volume hanavg/hanalv successfully resized.

四、扩文件系统
PO-HANA-PRD2:~ # df -h
