Re: [zfs-discuss] ZFS performance question over NFS
Hi Bob I don't know what the request pattern from filebench looks like but it seems like your ZEUS RAM devices are not keeping up or else many requests are bypassing the ZEUS RAM devices. Note that very large synchronous writes will bypass your ZEUS RAM device and go directly to a log in the main store. Small (= 128K) writes should directly benefit from the dedicated zil device. Find a copy of zilstat.ksh and run it while filebench is running in order to understand more about what is going on. Bob The pattern looks like: N-Bytes N-Bytes/s N-Max-RateB-Bytes B-Bytes/s B-Max-Rateops =4kB 4-32kB =32kB 958865695886569588656 88399872 88399872 88399872 90 0 0 90 666228066622806662280 87031808 87031808 87031808 83 0 0 83 636672863667286366728 72790016 72790016 72790016 79 0 0 79 631635263163526316352 83886080 83886080 83886080 80 0 0 80 668761666876166687616 84594688 84594688 84594688 92 0 0 92 490904849090484909048 69238784 69238784 69238784 73 0 0 73 660528066052806605280 81924096 81924096 81924096 79 0 0 79 689533668953366895336 81625088 81625088 81625088 85 0 0 85 653212865321286532128 87486464 87486464 87486464 90 0 0 90 692513669251366925136 86118400 86118400 86118400 83 0 0 83 So does it look good, bad or ugly ;) Thomas ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
Re: [zfs-discuss] Kernel panic on zpool import. 200G of data inaccessible!
It seems that obtaining an Oracle support contract or a contract renewal is equally frustrating. I don't have any axe to grind with Oracle. I'm new to the Solaris thing and wanted to see if it was for me. If I was using this box to make money then sure I wouldn't have any problem paying for support. I don't expect handouts and I don't mind paying. I trusted ZFS because I heard it's for enterprise use and now I have 200G of data offline and not a peep from Oracle. Looking on the net I found another guy who had the same exact failure. To my way of thinking somebody needs to standup and get this fixed for us and make sure it doesn't happen to anybody else. If that happens I have no grudge against Oracle or Solaris. If it doesn't that's a pretty sour experience for someone to go through and it will definitely make me look at this whole thing in another light. I still believe somebody over there will do the right thing. I don't believe Oracle needs to hold people's data hostage to make money. I am sure they have enough good products and services to make money honestly. Jim ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss

Jim You digitally signed a license agreement stating the following: *No Technical Support* Our technical support organization will not provide technical support, phone support, or updates to you for the Programs licensed under this agreement. To turn around and keep repeating that they're holding your data hostage is disingenuous at best. Nobody is holding your data hostage. You voluntarily put it on an operating system that explicitly states doesn't offer support from the parent company. Nobody from Oracle is going to show up with a patch for you on this mailing list because none of the Oracle employees want to lose their job and subsequently be subjected to a lawsuit. If that's what you're planning on waiting for, I'd suggest you take a new approach. Sorry to be a downer, but that's reality. --Tim ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss

I have my two drives the pool is on disconnected so if this ever gets resolved I can reinstall Solaris and start learning again. I believe you can configure VirtualBox for Windows to pass thru the disk with your unimportable rpool to guest OSs. Can OpenIndiana or FreeBSD guest import the pool? Does Solaris 11X crash at the same place when run from within VirtualBox?
