Troubleshooting：lvm调整分区时“Error parsing metadata for VG fedora”的解决

磁盘满了，由于使用的是lvm，想要扩容时发现无论lvs还是lvdisplay这类命令都会报同样的错：

[root@localhost qwang]# lvs
  Parse error at byte  (line ): unexpected token
  Error parsing metadata for VG fedora.
  Skipping volume group fedora
  Internal error: Volume Group fedora was not unlocked

各种搜索无果，翻出一个bug：https://bugzilla.redhat.com/show_bug.cgi?id=1119045

读到comment 30，试试

[root@localhost qwang]# uname -a
Linux localhost.localdomain
54.197.182.68 jbossas.alias.medium 3.17.-.fc20.x86_64 # SMP Fri Nov  :: UTC  x86_64 x86_64 x86_64 GNU/Linux

查看下hostname

[root@localhost qwang]# cat /etc/hostname
localhost.localdomain
54.197.182.68 jbossas.alias.medium

/etc/hostname里删去我自己加的一行54.197.182.68 jbossas.alias.medium

再查看下

[root@localhost qwang]# uname -a
Linux localhost.localdomain 3.17.-.fc20.x86_64 # SMP Fri Nov  :: UTC  x86_64 x86_64 x86_64 GNU/Linux

试试

[root@localhost qwang]# lvs
  LV   VG     Attr       LSize   Pool Origin Data%  Move Log Cpy%Sync Convert
  home fedora -wi-ao---- .34g
  root fedora -wi-ao----  .00g
  swap fedora -wi-ao----   .64g

问题解决！
