I want to use RHEL server 5 with thin-provisioned LUNs on IBM Storwize V7000. I don't need to release unused blocks, just need to have storage growing up as data grows up. Assuming the disk storage is generaly supported for use with RHEL5, can I use the thin-provisioning feature? Is it safe for data? As I understand the thin-provisioning problems, it should be. But I have not found any confirming document/article.
