调整google cloud kubernetes上的磁盘大小

您好，我正在尝试为kubernetes集群中的一个pod调整磁盘大小，按照上的步骤，我通过ssh连接到实例节点以遵循这些步骤，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

我试着从pod内部运行命令，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

现在可以通过直接更新持久卷声明的存储规范轻松完成此操作。参考这些帖子：
