Xen Dom0 下判断 DomU 的磁盘使用率

来源：互联网发布：chm 软件编辑：程序博客网时间：2024/05/29 04:01

从 xentop 大致可知：CPU%、MEM%、网络、I/O...等
但对于 DomU 磁盘的使用、如：

用了多少 inode、多少空间，还剩多少，是否快爆满、是否应该通知客户升级 Xen 硬盘

这些 xentop 就心有余而力不足啦

[root@Rocky ~]# xentop

这里使用 dumpe2fs 为您排除忧愁哦
虽然不是特别准确、但也不会太离谱了啦

[root@localhost ~]# dumpe2fs -h /dev/xvda1dumpe2fs 1.39 (29-May-2006)Filesystem volume name:   /Last mounted on:          <not available>Filesystem UUID:          218c169f-a405-4862-afe6-3913c81beb37Filesystem magic number:  0xEF53Filesystem revision #:    1 (dynamic)Filesystem features:      has_journal ext_attr resize_inode dir_index filetype needs_recovery sparse_super large_fileDefault mount options:    user_xattr aclFilesystem state:         cleanErrors behavior:          ContinueFilesystem OS type:       LinuxInode count:              767232Block count:              767095Reserved block count:     38354Free blocks:              439490Free inodes:              716246First block:              0Block size:               4096Fragment size:            4096Reserved GDT blocks:      187Blocks per group:         32768Fragments per group:      32768Inodes per group:         31968Inode blocks per group:   999Filesystem created:       Tue Apr  9 01:07:47 2013Last mount time:          Tue Apr  9 09:44:18 2013Last write time:          Tue Apr  9 09:44:18 2013Mount count:              3Maximum mount count:      -1Last checked:             Tue Apr  9 01:07:47 2013Check interval:           0 (<none>)Reserved blocks uid:      0 (user root)Reserved blocks gid:      0 (group root)First inode:              11Inode size:               128Journal inode:            8First orphan inode:       171042Default directory hash:   teaDirectory Hash Seed:      839d1c07-6fc3-4794-9526-92d5ef94fa19Journal backup:           inode blocksJournal size:             64M

从上面的：
Inode count, Block count, Free blocks, Free inodes, Block size
等就可以判断出硬盘的使用率情况
