緊急求助！vgscan -v 命令在雙機(jī)中的備機(jī)上運(yùn)行是否會(huì)導(dǎo)致錯(cuò)誤？

今天不小心在一臺(tái)HP雙機(jī)中的備機(jī)上執(zhí)行了 vgscan -v 命令，突然想起它可能會(huì)錯(cuò)誤地重新配置lvmtab文件，請(qǐng)問(wèn)現(xiàn)在應(yīng)當(dāng)如何處理，另外還有一臺(tái)主機(jī)在運(yùn)行，是否需要將這臺(tái)未改動(dòng)的機(jī)器中的VG導(dǎo)出然后加入備機(jī)中？vgscan -v 提示如下：

沒(méi)事,如果擔(dān)心,你把SG切到這臺(tái)機(jī)器上來(lái),然后再執(zhí)行一次VGSCAN

收到！謝謝sqmax的指點(diǎn)。

今天又研究了一把，發(fā)現(xiàn)確實(shí)沒(méi)有問(wèn)題，在lvmtab文件未損壞的情況下，vgscan 不會(huì)對(duì)lvmtab文件進(jìn)行重建。
