LVM,LV不自動(dòng)激活

luckyttl

存儲(chǔ)是創(chuàng)建vg之后在vg上創(chuàng)建lv,開(kāi)機(jī)的時(shí)候　LV不自動(dòng)激活，請(qǐng)問(wèn)除了在rc.local里寫(xiě)　vgchange -ay 還有沒(méi)有其它的辦法．

    LV不能自動(dòng)激活是什么個(gè)意思？？還是不能自動(dòng)掛載？

lv應(yīng)該一次激活之后以后就不用在激活了的啊。

就是開(kāi)機(jī)的時(shí)候　lv 是　inactive 狀態(tài)，要手工vgchange -ay　才變成 active 才能掛載．．本地的VG就可以自動(dòng)激活，，ip存儲(chǔ)上的就不靈了．．．suse,redhat 我試了，都是這樣

4.6 Automatically Activating Non-Root LVM Volume Groups
Activation behavior for non-root LVM volume groups is controlled by parameter settings in the /etc/sysconfig/lvm file.

By default, non-root LVM volume groups are automatically activated on system restart by /etc/rc.d/boot.lvm, according to the setting for the LVM_VGS_ACTIVATED_ON_BOOT parameter in the /etc/sysconfig/lvm file. This parameter allows you to activate all volume groups on system restart, or to activate only specified non-root LVM volume groups.

To activate all non-root LVM volume groups on system restart, ensure that the value for the LVM_VGS_ACTIVATED_ON_BOOT parameter in the /etc/sysconfig/lvm file is empty (""). This is the default setting. For almost all standard LVM installations, it can safely stay empty.

LVM_VGS_ACTIVATED_ON_BOOT=""
To activate only a specified non-root LVM volume group on system restart, specify the volume group name as the value for the LVM_VGS_ACTIVATED_ON_BOOT parameter:

LVM_VGS_ACTIVATED_ON_BOOT="vg1"
By default, newly discovered LVM volume groups are not automatically activated. The LVM_ACTIVATED_ON_DISCOVERED parameter is disabled in the /etc/sysconfig/lvm file:

LVM_ACTIVATED_ON_DISCOVERED="disable"
You can enable the LVM_ACTIVATED_ON_DISCOVERED parameter to allow newly discovered LVM volume groups to be activated via udev rules:

LVM_ACTIVATED_ON_DISCOVERED="enable"

這個(gè)我也碰到過(guò)，目前也無(wú)解，感覺(jué)是啟動(dòng)過(guò)程的問(wèn)題。
IP SAN是需要在網(wǎng)絡(luò)啟動(dòng)過(guò)后才能識(shí)別到存儲(chǔ)，但是fstab等應(yīng)該是在網(wǎng)絡(luò)服務(wù)開(kāi)始前就已經(jīng)執(zhí)行過(guò)了，所以在那個(gè)時(shí)間點(diǎn)上，服務(wù)器與存儲(chǔ)應(yīng)該是不通的。FC就不一樣了，在fstab掛在之前就已經(jīng)有連接了，所以可以自動(dòng)來(lái)掛在。

個(gè)人看法，歡迎板磚。
