[zfs-discuss] zpool errors - ZFS-8000-8A

2008-11-17 Thread Chris Cosby
One of my zpools (sol-10-u4-ga-sparc) has experienced some permanent errors. At this point, I don't care about the contents of the files in question, I merely want to cleanup the zpool. zpool clear doesn't seem to do anything at all. Any suggestions? # zpool status -v ccm01 pool: ccm01 state:

To further clarify Will's point... Your current setup provides excellent hardware protection, but absolutely no data protection. ZFS provides excellent data protection when it has multiple copies of the data blocks (1 hardware devices). Combine the two, provide 1 hardware devices to ZFS, and you

Re: [zfs-discuss] ZFS deduplication

2008-07-22 Thread Chris Cosby
To do dedup properly, it seems like there would have to be some overly complicated methodology for a sort of delayed dedup of the data. For speed, you'd want your writes to go straight into the cache and get flushed out as quickly as possibly, keep everything as ACID as possible. Then, a dedup

Re: [zfs-discuss] zfs patches in latest sol10 u2 patch bundle

2008-07-16 Thread Chris Cosby
S10U2 has zfs version=1. Any patches are just bug fixes (I'm not sure if there are any). If your intention is to get to a newer, later, greater ZFS, you'll need to upgrade. S10U5 has, for example, version=4. Differences in the versions of zfs can be found at

[zfs-discuss] Status of ZFS on Solaris 10

2008-07-07 Thread Chris Cosby
We're running Solaris 10 U5 on lots of Sun SPARC hardware. That's ZFS version=4. Simple question: how far behind is this version of ZFS as compared to what is in Nevada? Just point me to the web page, I know it's out there somewhere. -- chris -at- microcozm -dot- net === Si Hoc Legere Scis

I'm going down a bit of a different path with my reply here. I know that all shops and their need for data are different, but hear me out. 1) You're backing up 40TB+ of data, increasing at 20-25% per year. That's insane. Perhaps it's time to look at your backup strategy no from a hardware

From my usage, the first question you should ask your customer is how much of a performance hit they can spare when switching to ZFS for Oracle. I've done lots of tweaking (following threads I've read on the mailing list), but I still can't seem to get enough performance out of any databases on
