NFS on Fibre Channel LUN

[frozenrubystar]

Zipurman, hello!

I have only Fibre Channel storage. Can I use Fibre Channel LUN in SimpleBackup VM for /mnt/backups?
Should I create a NFS server on physical server? Maybe I can create a NFS server on SimpleBackup VM?
Please advise me a good practice for FC storage for backups.

You should be able to use a FC LUN mounted to /mnt/backups however I have not tested that. I recommend NFS as it allows read/write from multiple places without issues where a LUN should only be used by a single host. I would not recommend using the VM for the NFS as if your environment fails, your data would be stuck inside the VM disks.

I have iSCSI MPIO using 10GBe with dual SAN/HA and I used NFS for my backups as I find it works the best.

Zipurman thanks for very fast answer! Did I understand correctly that you are using a dedicated Linux server for NFS share on iSCSI LUN?

[zipurman]

I am using a Synology SAN for both iSCSI and NFS. I have my iSCSI using MPIO for all of my VM disks. You can see my test environment setup info here http://zipur.ca/ovirt-4-2-x-install-he-hosted-engine-4-hosts-2-san-ha/ . I then have the same Synology unit serving NFS shares for my backups. I then mount /mnt/backups on my SimpleBackupVM to point to the shared NFS storage on my Synology.

I use a GlusterFS volume and performance is good.
