VG是按什么顺序使用包含在其中的PV的
原帖由 "sql2000" 发表:
真不清楚这个问题,我刚用三块盘做的一个VG,不知道如果之中的一块盘坏了的话会出现什么情况.
谁确实遇到过一个VG中的一块盘坏了的情况?说说.
Hi,
If one of the 3 disks in a vg is bad, there are two situations:
1. If the bad disk contains active LV and data, then your affected file systems will NOT function correctly. You will see some read/write errors to these file systems. Also, some processes accessing these file systems will hang. Your syslog.log will log the disk errors, "dmesg" command will report errors too.
2. If the bad disk does not contain active LV, then you will only the problem logged in the syslog.log, "dmesg" will report error.
Hope this explains.
Also, 夏令时's teacher was definitely WRONG !!
