Hello,<br class="">
<br class="">
I have a disk array connected to my HA Proxmox infrastructure with 4
hosts on Fiber Channel and I configure the Thin provisionning on the
LUNs. On Proxmox, I created the LVM storage with the Volum Group
containing the PVs connected to the LUNs.<br class="">
With this method, I can't use 100% of the thin provisionning option
because on Proxmox, the LVM storage reserve 100% allocated disks to
the VMs.<br class="">
<br class="">
For example, on my disk array, I created a LUN of 400 Gb, only 260
Gb are allocated. On the Proxmox infra, there is 340 Gb used on the
total of 400 Gb. So, I can't benefit from the thin provisionning
option entirely.<br class="">
<br class="">
Do you know if there is a better method concerning the storage to
configure and use regarding a disk array connected on Fiber Channel
to benefit from the thin provisionning option please ?<br class="">
<br class="">
Best Regards,<br class="">
