Huge piles of disk with LVM and/or RAID - GPT/GUID??
I want to hang a hardware array of about 9 TB of storage on a SlackWare 12 server, but I'm using SCSI to connect to the disks.
I know that SCSI will not let me allocate more than 2 TB per LUN. I also know that LVM and software RAID will let me combine a few pieces of storage into a single manageable unit. I can't seem to find what the limits of this combination might be, but I've asked that question over on the server forum. I also heard that 64-bit Linux distros can use GPT partitioning to address larger volumes than a 32-bit OS can handle. Can SlackWare 12 be configured to use this partitioning scheme somehow? If so, where can I find some documentation on this process? |

I just found a link to describe LVM2 limits: http://wiki.novell.com/index.php/Lin...nt#LVM2_Limits
Novell says: Physical Extent size: Default 4MB, range from 8KB-16GB in powers of 2. There is no limit of number of extents in LVM2, therefore there is no need to adjust the extent size for large volumes I say, "Wow!" |
