How large volume? / ‘Large Block Device’ support
« on: October 04, 2006, 11:13:03 AM »
How large volume can the SmeServer handle? I have a Areca ARC-1220 hardware raid set up with RAID5 + spare on 8x500GB disks. That gives me 3Tb. But the installation program gives me som errors.. I cant paste it in here since it only shows up at my monitor when installing. I will write it down if necessary. But is there any known limits here? I have installed it with 2Tb volume before..

Will do. There should be no problem tu use 64bit LBA option on the RAID to enable larger volume size? In the manual it says: This option use 16 bytes CDB instead of 10 bytes. This option works on different OS wich support 16 bytes CDB, such as:
Windows 2003 with SP1
Linux kernel 2.6.x or later.

I was bored (or avoiding more important stuff) so I asked your question on the Centos IRC channel.

Quote from: "     irc://irc.freenode.net/centos"
Wil_Syd>   Are there any max hard disk size limits for a Centos 4.3 install ?
   <Zathrus>   Wil_Syd: yes. Are you planning to exceed a few exabytes of storage?
   <Evolution>   Wil_Syd: yes. you can't have more than 1 Exabyte per spindle.
   <Wil_Syd>   No.. just 3TB
   <Zathrus>   Wil_Syd: that's a non-issue.
   <Wil_Syd>   ok..thank you.
   <Evolution>   Wil_Syd: you can't boot to a 3 TB partition.
   grub gets freaked out.
   and fdisk won't see all the space. you have to use parted with gpt
   <Wil_Syd>   Evolution: oh.
   <Evolution>   so if you want a 3TB partition, make a small 100M boot partition
   <Zathrus>   Wil_Syd: what kind of RAID card are you using?
   <Evolution>   beyond that, there aren't really any limits other than what your hardware can handle
   <Wil_Syd>   I'm just passing on a question for someone installing SMEServer which is 4.3 based.
   There is their original question.. http://forums.contribs.org/index.php?topic=34031.msg145946#msg145946
   "Areca ARC-1220 hardware raid set up with RAID5 + spare on 8x500GB disks"
   <orc_orc>   Wil_Syd: Areca controller works fine w the provided driver from them in that config w centos
   <Wil_Syd>   orc_orc: thanks.
Regards,
William

IF I give advise.. It's only if it was me....

Or perhaps it is not a bug?

Using greater than 2TB volume in Linux by "LBA 64" option

Notice : Please make sure that your system have ‘Large Block Device’ support enabled.
 
From this page: http://www.webconnexxion.com/raid/info_pages.php?pages_id=43

Does SmeServer have ‘Large Block Device’ support enabled?
