Adam, Thanx for your answer. I often read your blog. :o) Anyway, will it be possible to change from raidz1 to raidz2? I am switching to raidz2 because if a drive fails, there is a high chance that another drive fails while rebuilding the zpool (Ive heard). I want to know my options to migrate t

Robin, LSI 3041er and 3081er are pci-e 4 and 8 ports sata cards; they are not hot-swap capable, as far as I know, but do work very well (I'm using several of them) in jbod and they're not too expensive. See this http://www.lsi.com/storage_home/products_home/host_bus_adapters/sas_hbas/lsisas304

Hi David, BP rewrite is an important component technology, but there's a bunch beyond that. It's not a high priority right now for us at Sun. What's the bug / RFE number for it? (So those of us with contracts can add a request for it.) I don't have the number handy, but while it might be

Your issue may be due to a problem I ran into with 'cw' not generating the proper arguments for the C compiler. I've only used the Sun Studio C compiler to build the kernel. My notes on how I build the kernel are on my blog, in two parts: https://blogs.cs.umbc.edu/willm1/2009/01/23/building-the-o

Re: [zfs-discuss] SSD (SLC) for cache...

2009-08-30 Thread Marcelo Leal
Thanks Adam, So, if i understand well, the MLC SSD more appropriate for read cache is more theory than pratice right now. Right? I mean, SUN is just using SLC SSD's? That would explain the only support for SLC on SUN hardware (x42xx) series. Thanks again. Leal [ http://www.eall.com.br/blog ]

[zfs-discuss] zfs performance cliff when over 80% util, still occuring when pool in 60% ?

Ok had a pool which got full - so performance tanked. Ran off and got some more disks to create a new pool to put all the extra data. Got the original pool down to 60% util, but the performance is still bad. Any ideas on how to get the performance back? Bad news is that the pool in question is
