Hi guys.

my resources-agents depend like so:

resource-agents-deps.target
○ ├─00\\x2dVMsy.mount
● └─virt-guest-shutdown.target

when I reboot a node VMs seems to migrated off it live a ok, 
but..
when node comes back on after a reboot, VMs fail to migrate 
back to it, live.
I see on such node

-> $ journalctl -lf -o cat -u virtqemud.service
Starting Virtualization qemu daemon...
Started Virtualization qemu daemon.
libvirt version: 9.5.0, package: 6.el9 (builder at centos.org, 
2023-08-25-08:53:56, )
hostname: dzien.mine.priv
Path '/00-VMsy/enc.podnode3.qcow2' is not accessible: No 
such file or directory

and I wonder if it's indeed the fact the the _path_ is 
absent at the moment cluster just after node start, tries to 
migrate VM resource...
Is it possible to somehow - seemingly my 
_resource-agents-deps.target_ does not do - assure that 
cluster, perhaps on per-resource basis, will wait/check a 
path first?
BTW, that paths is available and is made sure is available 
to the system, it's a glusterfs mount.

many thanks, L
