YUMの後に「/dev/mapper/rootvg-root_lv」をクリーンアップする方法は?

YUMの後に「/dev/mapper/rootvg-root_lv」をクリーンアップする方法は?

CentOSでYumアップデートを実行していますが、突然/dev/mapper/rootvg-root_lvのディスク容量が増えます。

私がその道に行こうとしたとき:

lrwxrwxrwx 1 root root       7 Aug 19 01:08 rootvg-var_lv -> ../dm-3

そのルートを検索すると、次のようになります。

何をすべきか、どのように掃除するのか分からないのですか?

rootこれらの操作を実行してファイルシステムを拡張できますが、追加の手順は複雑で、システム管理者が実行するのが最善です。

すべてのコマンドはユーザーとして実行されますroot

lvextend -L+1G /dev/mapper/rootvg-root_lv
resize2fs /dev/mapper/rootvg-root_lv

XFSコマンドを使用する必要がある場合

xfs_growfs /

これにより、ファイルシステムは1GB拡張されますが、説明で述べたように、他のファイルシステムから多くを「盗む」方が良いでしょう。
