hope anyone canhelp me for this issuse. New install for drbd.
I try to setup HA for the Asterisk installation here with CentOS 6.0. i able install CentOS, Asterisk, dahdi and etc. no issue. But when i try to install DRBD encoutner issue which cause server not able reboot.
When we start install DRBD follow the normal procedure, we run: yum install drbd83 kmod-drbd83 it actually pushes for a kernel upgrade (kmod-drbd83). Upon kernel update the system doesn’t boot up. even before rebooting (after yum install finishes) if we run service drbd start, we see a kernel panic.
If drbd is the high disk clustering software, I can think of no good reason why it should be anywhere near your PABX machine. PABX machines shuld do little else than run the PABX.
However, a kernel update will invalidate the installation of dahdi. Normally the result would simply be that dahdi can’t be found at startup. However, if the packager didn’t put it in the kernel version module directory, it could well cause a panic at boot time.
In any case, you need to be more precise about “doesn’t load”. There are a lot of messages about the loading process, which should give an indication of when things go wrong, and if it panics, there should be a panic message.
Dahdi won’t get loaded until quite late, and Asterisk runs in user space, so an early crash will rule out Asterisk, although there may be a conflict with your telephony hardware.
We use DRBD for the monitor, voicemail and database file-systems of our HA installs, This for example keeps voicemails in sync when the system fails over and the database in sync.
Yes, DRBD installed. if we run “service drbd start”, we see a kernel panic. When reboot the server it boot up to certain stage it hang. I did capture the screen by camera. I can email you. Hope this clear.
