we have 2 Nodes
Node "t1" has 2 HDD (VDs) RAID1 and Node f1 has only 1 HDD (VD)
we have installed proxmox 4.4 in both the Nodes

In Server t1
VD1 has proxmox so it created local(t1) and local-lvm (t1)
VD2 is made anothe LVM thin and added with name maganet-hdd(t1)

in Server f1
VD1 has proxmox so it created local(f1) and local-lvm(f1)

i have created the cluster it shows something like this

Where in f1 the meganet-hdd is not available and summary says Usage as N/A

So i decided to remove from the storage.cfg, then it removed in both f1 and t1 because it will be synced with all the nodes in the cluster

So i added back then its started showing the both f1 and t1 has meganet-hdd but this time summary is same as local-lvm(f1)

How to solve this in-consistancy?

Not sure if others can post and comment. When I tested ThinLVM when it was an 'early' feature - it gave me more trouble than it was worth. So I moved to a model of (a) use non-thin LVM, if I must use LVM; or (b) If I must have Thin then use local disk or NFS based shared storage; both of which support thin very reliably and without issue.

Possibly LVM_Thin has evolved to a place of lovely happy stability since my testing. Possibly some others with experience will reply on this thread ?

you have to limit the storages to the nodes they exist on so
local and local-lvm exist on all,
but meganet-hdd only exists on t1

you can do this on the gui via datacenter->storage
