[zfs-discuss] convert raidz from osx

2009-10-08 Thread dirk schelfhout
I am converting a 4 disk raidz from osx to opensolaris. And I want to keep the data intact. I want zfs to get access to the full disk instead of a slice. I believe like c8d0 instead off c8d0s1. I wanted to do this 1 disk at a time and let it resilver. what is the proper way to do this. I tried, I

Re: [zfs-discuss] strange pool disks usage pattern

2009-10-08 Thread Maurilio Longo
By the way, there are more than fifty bugs logged for marevell88sx, many of them about problems with DMA handling and/or driver behaviour under stress. Can it be that I'm stumbling upon something along these lines? http://bugs.opensolaris.org/bugdatabase/view_bug.do?bug_id=6826483 Maurilio.

Dirk, I'm not sure I'm following you exactly but this is what I think you are trying to do: You have a RAIDZ pool that is built with slices and you are trying to convert the slice configuration to whole disks. This isn't possible because you are trying replace the same disk. This is what

Re: [zfs-discuss] convert raidz from osx

2009-10-08 Thread Dirk Schelfhout
yes, that was what I was doing. I wanted to give the raidz whole disks because grub didn't want to install. ( I forgot which command I used . bootadm ? ) I have another slice free on a shared disk with osx and win7 but I am having problems with grub. I will try that again and document it

[zfs-discuss] zfs send/receive performance concern

2009-10-08 Thread Rani Raj
I am running zfs send/receive on a ~1.2Tb zfs spread across 10x200Gb LUNs. Has copied only 650Gb in ~42Hrs. Source pool and destination pool are from the same storage sub system. Last time when ran, took ~20Hrs. Something is terribly wrong here. What do i need to look to figure out the reason?

[zfs-discuss] ZFS saved my data success story

2009-10-08 Thread Carson Gaspar
To recap for those who don't recall my plaintive cries for help, I lost a pool due to the following sequence of events: - One drive in my raidz array becomes flaky, has frequent stuck I/Os due to drive error recovery, trashing performance - I take flaky drive offline (zpool offline...) - I

[zfs-discuss] MPT questions

2009-10-08 Thread Frank Middleton
In an attempt to recycle some old PATA disks, we bought some really cheap PATA/SATA adapters, some of which actually work to the point where it is possible to boot from a ZFS installation (e.g., c1t2d0s0). Not all PATA disks work, just Seagates, it would seem, but not Maxstors. I wonder why?
