[DRBD-user] drbdadm verify resource with cron

[Dan Barker]

There is no such thing as in sync or out of sync if the resource is standalone. It simply is what it is.

hi,
when a drdb-device is standalone + primary, what tells me oss > 0 ?
dangerous or is it just a difference to the state when it was connected last time ?

thanks andreas

You are not looking for a return code, and the oos counter in /proc/drbd might not go up for hours.

What you want is to configure the Out Of Sync handler. Mine (cron to run weekly, one resource per night) says:
                out-of-sync      "/usr/lib/drbd/notify-out-of-sync.sh myemail at address.tld<mailto:myemail at address.tld>";

When I get these email, I can remedy the situation; disconnect/connect to resync, replace a drive if it's bad, whatever. It only sends the email about once per year (not using RAID).

Dear readers

I have configured drbd with resource syncer

Since everything is running fine, the command
#drbdadm verify resource

outputs nothing

I'm wondering what the output could be if some re-sync is needed, this is meant to use it with cron.

Thank you for hinting

Roberto
