What would happen if the export domain (via NFS) was extended (say, while t=
he server was doing a reboot?) id like to extend the space of my export do=
main from 200 to 500GB (with lvm commands).
How will ovirt react to finding the size of the export domain changed? Ple=
ased or unpleased?
Thanks,
jonathan

ovirt should not react in any way :)
the size should be updated by queries that are sent to vdsm on domains
status.
If you want to be extra careful you can always put the export domain in
maintenance before the extend :)

I think vdsm domains do have their own meta-data except the lvm or posix
file system meta data.
If you want to be extra careful you can always put the export domain
in
maintenance before the extend :)
If the export domain come back to life, I think
the domain meta data
should be invalidated after the extend.

I think vdsm domains do have their own meta-data except the lvm or
posix file system meta data.
the export domain is an NFS domain and the size is not
listed in its
metadata. much like posix which is based on file type storage, if we
extend the size in the storage server itself the domain size will be
updated with no issues or changed to the metadata.
you are correct regarding iscsi domain types which would have a problem
with extending a lun in the storage side.
extend for iscsi is done via the ovirt by editing the domain and adding
more luns since extend of the used lv on the storage side will cause
issues in the metadata.

If the export domain come back to life, I think the domain meta data
should be invalidated after the extend.
since its not iscsi type domain the extend
done on the server side to
extend the domain should not be a problem

file system meta data.
iirc, the MD no longer cares about SD size. so for block storage it is a
matter of refreshing the hosts.
but in any case, since export is NFS, i don't remember any issues with
extending it.

So you have a block device in NFS server to be extended from 200 to
50GB? I think you should extend both the block device and the file
system on the block device in the server side. To oVirt, it doesn't
save the size in storage domain' meta-data and I believe the size is
only stored in the engine server. The only issue is before the engine
refresh its metadata in the next time, there is a window with the
meta-data out of sync. Please let us know if it is successful.
