Re: [zfs-discuss] moving files from one fs to another, splittin/merging

2009-11-14 Thread george white
Is there a way to use only 2 or 3 digits for the second level of the var/pkg/download cache? This directory hierarchy is particularly problematic relative to moving, copying, sending, etc. This would probably speed up lookups as well. -- This message posted from opensolaris.org

Hello all, Are there any best practices / recommendations for ways of doing this ? In this case the ZVOLs would be iSCSI LUNS containing ESX VMs .I am aware of the of the need for the VMs to be quiesced for the backups to be useful. Cheers. -- This message posted from opensolaris.org

I use Intel Q9450 + P45 Gigabyte EP45-DS3P. I put the AOC card into a PCI slot, not PCI-x. About the HBA, I have no idea. So I had half of the drives in the AOC card, and the other half on the mobo SATA ports. Now I have all drives to the AOC card, and suddenly a scrub takes 15h instead of 8h.

The ICH10 has a 32-bit/33MHz PCI bus which provides 133MB/s at half duplex. you are correct, I thought ICH10 used a 66Mhz bus, when infact its 33Mhz. The AOC card works fine in a PCI-X 64Bit/133Mhz slot good for 1,067 MB/s even if the motherboard uses a PXH chip via 8 lane PCIE.

Yes indeed, but my point was that it was not always so. This change was something I and others campaigned for quite some time ago. Indeed, in the early days of ZFS evangelism (when I was still at Sun) the issue came up rather often. In those days there were even more reasons not to use a
