storage - why I cannot change the type

[svacaroaia]

Hi,

I have a 2 node Proxmox cluster
Based on the advises posted here and the equipment I have, I decided to configure storage as follows:
- volume created on HP MSA 2000 and made available to both hosts as fiber channel attached disks
- LVM groups created on the above and shared on servers

I was able to create the volumes and LVM group using the following
- configure multipath to "see" the volume correctly
- pvcreate /dev/mapper/mpathX
- vgcreate VOL /dev/mapper/mpathX
- lvcreate --size XXg VOL

Then, using Proxmox GUI, i have added the above LVM group to the storage
I am able to store images and use them for migrating from one server to another

However, I was not able to specify ( nor to edit ) the type of storage ( images, iso, backup ..etc) - this option is available only when editing the "local" storage

Question:
- how can I specify the type of storage ?
- without a storage type "backup" I cannot do backups

Thanks

LVM can only store images, because there is no filesystem. Backups needs a file system (type NFS or directory).

I guess the same is true for ISO ( I need a directory )

In this case the best approach in a clustered configuration is to create directory/NFS on primary for backups / ISO then NFS mounting it on the other servers
?

Hi,
I think thats not the best idea - if node 1 died, you don't have the isos on the second node. Esp. if you use cd-live-distros...
I use for important isos a directory which created on all nodes, where I rsync the content between all cluster-nodes (storage isn't marked as shared).
