Re: [zfs-discuss] Any use for extra drives?

2011-03-25 Thread Anonymous
Generally, you choose your data pool config based on data size, redundancy, and performance requirements. If those are all satisfied with your single mirror, the only thing left for you to do is think about splitting your data off onto a separate pool due to better performance etc. (Because

Hi. I have a development system on Intel commodity hardware with a 500G ZFS root mirror. I have another 500G drive same as the other two. Is there any way to use this disk to good advantage in this box? I don't think I need any more redundancy, I would like to increase performance if possible. I

Thanks guys. I'm only planning to move some directories. Not the complete dataset. Just a couble of Gb's. Would it be save to use mv Of course, provided your system doesn't crash during the move. Using rsync -avPHK --remove-source-files SRC/ DST/ isn't that just as copying files ?

I asked what I thought was a simple question but most of the answers don't have too much to do with the question. Now it seems to be an argument of your filesystem is better than any other filesystem. I don't think it is because I have seen the horror stories lurking on this list. I had no

[zfs-discuss] How can I copy a ZFS filesystem back and forth

2012-12-03 Thread Anonymous
I turned compression on for several ZFS filesystems and found performance was still fine. I turned gzip on and it was also fine and compression on certain filesystems is excellent. I realize all the files that were on the filesystem when compression=on did not get the benefit of gzip when I set

If you plan to generate a lot of data, why use the root pool? You can put the /home and /proj filesystems (/export/...) on a separate pool, thus off-loading the root pool. I don't, it's a development box with not alot happening. My two cents, thanks

Hi Dave, Hi Cindy. Consider the easiest configuration first and it will probably save you time and money in the long run, like this: 73g x 73g mirror (one large s0 on each disk) - rpool 73g x 73g mirror (use whole disks) - data pool Then, get yourself two replacement disks, a good

It depends on the model. Consumer models are less likely to immediately flush. My understanding that this is done in part to do some write coalescing and reduce the number of P/E cycles. Enterprise models should either flush, or contain a super capacitor that provides enough power for the
