Re: [zfs-discuss] corrupt zfs stream? checksum mismatch

Hi Richard, Thanks for the detailed reply, and the work behind the scenes filing the CRs. I've bookmarked both, and will keep a keen eye on them for status changes. As Miles put it, I'll have to put these dumps into storage for possible future use. I do dearly hope that I'll be able to recover m

Hi folks, Perhaps I was a little verbose in my first post, putting a view people off. Does anyone else have any ideas on this one. I can't be the first person to have had a problem with a zfs backup stream. Is there nothing that can be done to recover at least some of the stream. As another hel

Hi Folks, I'm in the very unsettling position of fearing that I've lost all of my data via a zfs send/receive operation, despite ZFS's legendary integrity. The error that I'm getting on restore is: receiving full stream of faith/[EMAIL PROTECTED] into Z/faith/[EMAIL PROTECTED] cannot receive: in

can read at 60-70Mb/sec. Why am I not getting 65*8 (500MB/sec+) performance. Maybe it's the marvell driver at fault here? My thinking is that I need to get raid0 performing as expected before looking at raidz, but I'm afraid I really don't know where to begin. All thought
