Title: Large Capacity Disk Configuration
Post by: ddougan on March 08, 2011, 07:38:06 PM

I have a new server with hardware RAID 5 and 4 TB of usable storage in one logical disk. I've installed SME Server (7.5.1) with the noraid option and with LVM. On installation, I see the filesystem is using only 2TB and fdisk reports an incorrect cylinder boundary for the large partition:

# fdisk -l

Disk /dev/sda: 3999.6 GB, 3999688294400 bytes
255 heads, 63 sectors/track, 486267 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

   Device Boot      Start         End      Blocks   Id  System
/dev/sda1   *           1          13      104391   83  Linux
/dev/sda2              14          13  2147480842+  8e  Linux LVM

I understood that there was a logical limit of something like 32 TB with the ext3 filesystem. Is that not correct? Should I reconfigure the RAID controller to two logical disks and if so, will the installation manage both with LVM to provide a 4 TB partition?

Thanks,

Des

Hmmm. I haven't tried this on my sme main. But I do have an extra set of disks configured as 4x2TB with an LVM directly on top making it a full 8TB. So this type of config in general should work.

It could be an issue with the installer as it should just work. So I suggest you file a bug and track it that way.
