单块硬盘创建的逻辑卷扩盘

1、给控制台物理卷增加空间
查询扩展结果

nvme1n1259:00150G0disk └─data-pg253:00100G0lvm /data

2、同步物理卷大小

[root@postgres-prod base]# pvresize /dev/nvme1n1Physical volume"/dev/sdb"changed1physical volume(s)resized or updated /0physical volume(s)not resized

3、将所有空间扩展到lvs

[root@postgres-prod base]# lvextend -r -l +100%FREE /dev/mapper/data-pgSize of logical volume data/pg changed from<100.00GiB(25599extents)to<150.00GiB(38399extents). Logical volume data/pg successfully resized. meta-data=/dev/mapper/data-pgisize=512agcount=33,agsize=819136blks=sectsz=512attr=2,projid32bit=1=crc=1finobt=1,sparse=1,rmapbt=0=reflink=1bigtime=0inobtcount=0data=bsize=4096blocks=26213376,imaxpct=25=sunit=1swidth=1blks naming=version2bsize=4096ascii-ci=0,ftype=1log=internal logbsize=4096blocks=6399,version=2=sectsz=512sunit=1blks, lazy-count=1realtime=noneextsz=4096blocks=0,rtextents=0data blocks changed from26213376to39320576

4、查看扩展情况

[root@postgres-prod base]# lsblkNAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT nvme1n1259:00150G0disk └─data-pg253:00150G0lvm /data
