[zfs-discuss] Re: ZFS checksum error detection

2007-03-16 Thread Anton B. Rang
It's possible (if unlikely) that you are only getting checksum errors on metadata. Since ZFS always internally mirrors its metadata, even on non-redundant pools, it can recover from metadata corruption which does not affect all copies. (If there is only one LUN, the mirroring happens at differe

[zfs-discuss] ZFS checksum error detection

2007-03-16 Thread Thomas Nau
Hi all. A quick question about the checksum error detection routines in ZFS. Surely ZFS can decide about checksum errors in a redundant environment but what about an non-redundant one? We connected a single RAID5 array to a v440 as a NFS server and while doing backups and the like we see the "

Thanks for the links, but this is not really the kind of data I'm looking for. These focus more on I/O. I need information on the memory cahing, and so on. Specifically, I need data that shows how starting up a 10GB SGA database on a 16GB machine will not be able to flush the ZFS cache as quickl

[zfs-discuss] ZFS performance with Oracle

I thought I'd share some lessons learned testing Oracle APS on Solaris 10 using ZFS as backend storage. I just got done running 2 months worth of performance tests on a v490 (32GB/4x1.8Ghz dual core proc system with 2xSun 2G HBAs on separate fabrics) and varying how I managed storage. Storage us

[zfs-discuss] ZFS and file checksums

2007-03-16 Thread Alexander Kolbasov
I am wondering if it is possible (or whether it is a valid RFE) to support file checksums on ZFS (e.g. in the extended file attributes). ZFS also has block-level checksums - how complicated would it be to construct file-level checksums from that? These checksums may be used, for example, to qui
