在google上调整磁盘大小

Question

嗨，im试图为我的kubernetes集群中的一个吊舱重新调整磁盘的大小，按照文档上的步骤，我在实例节点中执行步骤，但这给了我一个错误。

sudo growpart /dev/sdb 1
WARN: unknown label 
failed [sfd_dump:1] sfdisk --unit=S --dump /dev/sdb
/dev/sdb: device contains a valid 'ext4' signature; it is strongly recommended to wipe the device with wipefs(8)
 if this is unexpected, in order to avoid possible collisions
sfdisk: failed to dump partition table: Success
FAILED: failed to dump sfdisk info for /dev/sdb

我试着在舱内运行命令，但即使在那里也找不到磁盘。

root@rc-test-r2cfg:/# df -h
Filesystem      Size  Used Avail Use% Mounted on
overlay          59G  2.5G   56G   5% /
/dev/sdb         49G   22G   25G  47% /var/lib/postgresql/data

root@rc-test-r2cfg:/# lsblk
NAME   MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
sdb      8:16   0  96G  0 disk /var/lib/postgresql/data
sda      8:0    0  60G  0 disk
└─sda1   8:1    0  60G  0 part /etc/hosts

root@rc-test-r2cfg:/# growpart /dev/sdb 1
FAILED: /dev/sdb: does not exist

其中/dev/sdb是磁盘位置

现在，通过直接更新持久性卷声明的存储规范，可以很容易地做到这一点。见这些职位以供参考：
