If you're building from scratch, please choose nearline/midline SAS disks instead of SATA if you're looking for capacity. For detailed reasoning, see: http://serverfault.com/a/331504/13325 For the server, I've had great success with HP ProLiant systems, focusing on the DL380 G6/G7 models. If you c

I could use some help with choosing hardware for a storage server. For budgetary and density reasons, we had settled on LFF SATA drives in the storage server. I had closed in on models from HP (DL180 G6) and IBM (x3630 M3), before discovering warnings against connecting SATA drives with SAS expande

Yep, well said, understood, point taken, I hear you, you're preaching to the choir. Have faith in Santa. A few comments: 1. I need more info on the x86 install issue. I haven't seen this problem myself. 2. We don't use slice2 for anything and its not recommended. 3. The SMI disk is a long-stan

The issue is really quite simple. The solaris install, on x86 at least, chooses to use slice-0 for the root partition. That slice is not created by a default format/fdisk, and so we have the web strewn with prtvtoc path/to/old/slice2 | fmthard -s - path/to/new/slice2 As a way to cause the t

Hi Gregg, Yes, fighting with partitioning is just silly. Santa will bring us bootable GPT/EFI labels in the coming year is my wish so you will be able to just attach disks to root pools. Send us some output so we can see what the trouble is. In the meantime, the links below might help. Thanks

Hi Tim, No, in current Solaris releases the boot blocks are installed automatically with a zpool attach operation on a root pool. Thanks, Cindy On 12/15/11 17:13, Tim Cook wrote: Do you still need to do the grub install? On Dec 15, 2011 5:40 PM, "Cindy Swearingen" mailto:cindy.swearin...@ora

You can just do fdisk to create a single large partition. The attached mirror doesn't have to be the same size as the first component. On Thu, Dec 15, 2011 at 11:27 PM, Gregg Wonderly wrote: > Cindy, will it ever be possible to just have attach mirror the surfaces, > including the partition tab
