Sorry if this is a newbie question.
I have a number of resources (VM's) on a two node system for which the
resource names are now misleading and I would like to change them. Is it
possible?
Do I just change the .res files or some other config? Do I have to shutdown
all VM's and change both node configs at the same time?
I can't find any documentation how to (safely) do it.
Could anybody point me to it?
You created these manually, right? No plugins/drbdmanage/LINSTOR involved?
If so, sure, you can do that. "down" it on one side, rename it in the
res file, and "up" it again. Check how you used the DRBD block device.
Via the minor? Good. Via the udev generated symlink? You need to adapt
your setup.
And again, this is all for a manual setup. All plugins I can imagine/we
provide would be horribly confused if somebody changes the name
underneath them.
Thanks.... this was set up by someone else and I just do basic
maintenance on it.
Definitely not Linstor, and I'm not aware of drbdmanage, which is not
btw installed.
I have this udev rule:
KERNEL=="drbd*", IMPORT{program}="/sbin/drbdadm sh-udev minor-%m",
NAME="$env{DEVICE}", SYMLINK="drbd/by-res/$env{RESOURCE}
drbd/by-disk/$env{DISK}"
but I admit I have no idea what to do with it :)
thanks
