Troubleshooting：lvm調整分區時「Error parsing metadata for VG fedora」的解決

磁盤滿了，因爲使用的是lvm，想要擴容時發現不管lvs仍是lvdisplay這類命令都會報一樣的錯：

[root@localhost qwang]# lvs
  Parse error at byte 1591 (line 100): unexpected token
  Error parsing metadata for VG fedora.
  Skipping volume group fedora
  Internal error: Volume Group fedora was not unlocked

各類搜索無果，翻出一個bug：https://bugzilla.redhat.com/show_bug.cgi?id=1119045

讀到comment 30，試試

[root@localhost qwang]# uname -a
Linux localhost.localdomain
54.197.182.68 jbossas.alias.medium 3.17.4-200.fc20.x86_64 #1 SMP Fri Nov 21 23:26:41 UTC 2014 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裏刪去我本身加的一行54.197.182.68 jbossas.alias.medium

再查看下

[root@localhost qwang]# uname -a
Linux localhost.localdomain 3.17.4-200.fc20.x86_64 #1 SMP Fri Nov 21 23:26:41 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux

試試

[root@localhost qwang]# lvs
  LV   VG     Attr       LSize   Pool Origin Data%  Move Log Cpy%Sync Convert
  home fedora -wi-ao---- 180.34g                                             
  root fedora -wi-ao----  50.00g                                             
  swap fedora -wi-ao----   7.64g

問題解決！
