Now the test for the Vertex 2 Pro. This was fun. For more explanation please see the thread Crucial RealSSD C300 and cache flush? This time I made sure the device is attached via 3GBit SATA. This is also only a short test. I'll retest after some weeks of usage. cache enabled, 32 buffers, 64k

[zfs-discuss] ZFS root recovery SMI/EFI label weirdness

I've been testing the ZFS root recovery using 10u6 and have come across a very odd problem. When following this procedure I the disk I am setting up my rpool on keeps reverting to an EFI label. http://docs.sun.com/app/docs/doc/819-5461/ghzur?l=ena=view Here is what the exact steps I am doing;

I've discovered the source of the problem. zpool create -f -o failmode=continue -R /a -m legacy -o cachefile=/etc/zfs/zpool.cache rpool c1t0d0 It seems a root pool must only be created on a slice. Therefore zpool create -f -o failmode=continue -R /a -m legacy -o

[zfs-discuss] Maximum zfs send/receive throughput

2010-06-25 Thread Mika Borner
It seems we are hitting a boundary with zfs send/receive over a network link (10Gb/s). We can see peak values of up to 150MB/s, but on average about 40-50MB/s are replicated. This is far away from the bandwidth that a 10Gb link can offer. Is it possible, that ZFS is giving replication a too

Sean, If you review the doc section you included previously, you will see that all the root pool examples include slice 0. The slice is a long-standing boot requirement and is described in the boot chapter, in this section: http://docs.sun.com/app/docs/doc/819-5461/ggrko?l=ena=view ZFS

Good morning all. This question has probably poped up before, but maybe not in this exact way… I am planning on building a SAN for my home meta centre, and have some of the raid cards I need for the build. I will be ordering the case soon, and then the drives. The cards I have are 2 8 port

Tiernan, Hardware redundancy is important, but I would be thinking about how you are going to back up data in the 6-24 TB range, if you actually need that much space. Balance your space requirements with good redundancy and how much data you can safely back up because stuff happens: hardware
