lvcache on partitioned ssd or only on full device?
Hi, If possible, I would like to configure a hyperconverged cluster with hosts' system partitions and the gluster's lvcache on partitions of SSDs in RAID1. Is it possible to define the lvcache on a partitioned device like /dev/sdaX ; or is it only supported to pass a whole device like /dev/sdb ? Thanks for your help
Is this right? 1. Define the area where the Hypervisor OS will be installed on the SSD Raid1 2. Partition the disk 3. Using lvm as part of gluster brick cache If what I understand is correct, configuration is possible but not recommended. When the volume has a lot of I / O, it can cause problems with the hypervisor. (Response delay, etc.) I have shed blood sweat & tears. If you want to use lvcache, be sure to use a separate flash disk. Never use NVMe. It has its own limit (bottleneck) and does not enjoy the benefits of nvme.
Ok, thanks for for your input :)
