[opensuse] data integrity with ZFS or alternatives
Hi folks, I am looking for a way to guarantee data integrity on my Linux box (11.4). BTRS does not seem to have anything for that. ZFS is only recently available natively (i.e. Without FUSE) on Linux. That port by KQStor is not built on opensuse. Has anyone tried to port it to opensuse? I am looking to protect against silent bit rot. I am looking for file or partition level protection. I know BTRS and ZFS are both not "mature" on Linux. Any alternatives othere than checksumming files individually?

How about sector level? The kernel got support for that about 3 years ago: http://lxr.linux.no/#linux+v2.6.38/Documentation/block/data-integrity.txt I don't know how to utilize it or what specific hardware you need to have to support it. (I do know the disk drive / raid array has to support the Data Integrity extensions, but again I don't know how common / rare that is.)

Do you happen to have a RESTful link to the documentation? That link doesn't appear to lead to a .txt file, just some empty bling container. Cheers, Dave -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Hmm, it worked fine for me. -- Per Jessen, Zürich (9.8°C) -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

But you probably didn't use REST. You probably had Javascript enabled. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

ah, quite probably. Certainly I had javascript enabled, yes. (I'll have to look up what REST is). -- Per Jessen, Zürich (10.9°C) -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

I've looked it up, but I didn't get it. Whats the purpose of REST and why would I use it? (less than three lines please :-) ) Anyway, you could just get the document here: file:///usr/src/linux/Documentation/block/data-integrity.txt -- Per Jessen, Zürich (11.0°C) -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Worked for me but it's just <kernel-source>/Documentation/block/data-integrity.txt from the kernel source which you can get countless ways and places. Here's the same right from kernel.org but the link is a bit uglier and it's only as permanent as kernel.org's use of gitweb. http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=blob_plai... -- bkw -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
