I know that there is a monitoring process which monitors each Storage
Domain, so I guess that if you will have multiple storage domains this will
make the monitor runs every time multiple times, but I think that the
affect is insignificant on the Host or the Storage Domain.
You should also consider the limitation of logical volumes in a volume
group,
IINM LVM has a default limit of 255 volumes (I'm not sure how it behaves
regarding efficiency if you use more volumes)
oVirt uses LV also for snapshots so with one storage domain you might get
to this limit pretty quick

Hi,
thx for you input
both aren’t problems for me, all domains are from the same storage and so
can’t be maintained independently.
Are there performance problems with only one Domain (like waiting for
locks etc.) which I don’t have that much with multiple?
Thx Christian

There are many factors that can be discussed on this issue,
two things that pop up on my mind are that many storage domains will make
your Data Center be more robust and flexible, since you can maintain part
of the storage domains which could help with upgrading your storage server
in the future or fixing issues that might occur in your storage, without
moving your Data Center to a non operational state.
One storage domain is preferrable if you want to use large disks with your
VMs that small storage domains does not have the capacity to do so

Hi,
Ii am about to migrate to a new storage.
Whats the best practice in sizing?
1 big Storage Domain or multiple smaller ones?
My current Setup:
11 Hosts
7 FC Storage Domains 1 TB each
Can anyone tell me the pro and cons of 1 vs. many?
Thx Christian
