I have a 1600GB ext3 partition currently in use and am planning to grow that by ~ 6000GB. From the documentation that I have found, it looks like I may be able to do this without modification to my system. However, I'm querying to verify it.. Current ext3 filesystem has 4KB block size (supposedly good to 16TB total.) I have one LV defined with a size of "3456106496". I have two PVs, the first (sdc) with a size of "1646481408" and a PE size of "1048576", the second (sdd) with a size of "1815863296" and a PE size of "1048576" as well. Allocation of the ext3 is at "1152717492" 1k-blocks used and "548221548" 1k-blocks available right now. The RAID system that the storage resides on has, up until now, sort-of enforced a roughly <2TB limit per device (2 cabinets currently with 1600GB and the RAID can not span cabinets,) I can continue to allocate ~ 2TB per device to fit within the kernel 2.4 32-bit block device limit. I do not know if I am actually limited to 1TB per device as I've read before from Redhat, so that may be a possibility. Here is my current vgdisplay [root@swlx201 root]# vgdisplay --- Volume group --- VG Name data VG Access read/write VG Status available/resizable VG # 0 MAX LV 256 Cur LV 1 Open LV 1 MAX LV Size 2 TB Max PV 256 Cur PV 2 Act PV 2 VG Size 1.61 TB PE Size 1 GB Total PE 1648 Alloc PE / Size 1648 / 1.61 TB Free PE / Size 0 / 0 Any comments, questions, etc VERY welcome.
